How Can I learn OOPs Concepts Easily

First Step

Object-Oriented Programming (OOP) is a technique of computer programming model that organizes software design around data, or objects, rather than functions and logic. We can define an object that as a data field which has unique attributes and behaviour.

Second Step

• Try to know What Is Object-Oriented Programming concepts?
• To better known OOP’s concept try to relate with the real world problems and how real-world problems can be solved by OOP’s.
• Why study of Object-Oriented Programming is necessary and important to learn?
• Know the limitations and advantages of OOP.

Third Step

Now understand above steps try to focus on Structure of Object-Oriented Programming Language as below:-

• What is the definition of Class.
• What is definition Object.
• Know the difference between Class and Object.
• How to use of Classes and Object in program.
• Try to know real-world scenario of class and object.
• Understand all Access Modifiers (public, private, protected, etc.) in OOP’s.

Fourth Step

Important Keywords in OOPs to learn and understand:

• Final Keyword
• Explicit keyword
• This Keyword
• new Keyword
• const keyword
• super keyword etc…

Example:-

#include <iostream>

#include <string>

using namespace std;

class MyExample

{       

public:            

int numdata;       

string stringdata; 

};

int main()

{

MyExample myObj; 

myObj.stringdata = “Your value is…”;

myObj.numdata = 108;

cout << myObj.stringdata;

cout << myObj.numdata << “\n”;

return 0;

}

What is Data Structure?

Definition

A data structure is a data organization, management, and storage format that is usually chosen for efficient access to data. More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data.

Data Types and Their Relationship With Data Structures

To answer the question of what is data structure, there are three basic data types to understand.

Ø  Abstract.

Abstract data is defined by how it behaves. This type encompasses graphs, queues, stacks, and sets.

Ø  Composite (or Compound).

Composite data comprises combined primitive data types and includes arrays, classes, records, strings, and structs. They may also consist of other composite types.

Ø  Primitive.

Primitive data is classified as basic data and consists of Boolean, characters, integers, pointers, and fixed- and floating-point numbers.

These data types are the building blocks of data structures.

What Are the Classifications of Data Structure?

Ø  Linear and Nonlinear.

Linear structures arrange data in a linear sequence, such as found in an array, list, or queue. In nonlinear structures, the data doesn’t form a sequence but instead connects to two or more information items, like in a tree or graph.

Ø  Static and Dynamic.

As the term implies, static structures consist of fixed, permanent structures and sizes at compile time. The array reserves a set amount of reserve memory set up by the programmer ahead of time. Dynamic structures feature non-fixed memory capacities, shrinking or expanding as required by the program and its execution requirements. Additionally, the location of the associated memory can change.

Ø  Homogenous and Non-Homogenous.

Homogenous data structures consist of the same data element type, like element collections found in an array. In non-homogenous structures, the data don’t have to be the same type, such as structures.

The Different Data Structure Types

So far, we have touched on data types and data structure classifications. Our walk through the many elements of data structures continues with a look at the different types of data structures.

Ø  Array.

Arrays are collections of data items that are of the same type, stored together in adjoining memory locations. Each data item is known as an “element.” Arrays are the most basic, fundamental data structure. Aspiring Data Scientists should master array construction before moving on to other structures such as queues or stacks.

Ø  Graphs.

Graphs are a nonlinear pictorial representation of element sets. Graphs consist of finite node sets, also called vertices, connected by links, alternately called edges. Trees, mentioned below, are a graph variation, except the latter has no rules governing how the nodes connect.

Ø  Hash Tables.

Hash tables, also called hash maps, can be used as either a linear or nonlinear data structure, though they favor the former. This structure is normally built using arrays. Hash tables map keys to values. For example, every book in a library has a unique number assigned to it that facilitates looking up information about the book, like who has checked it out, its current availability, etc. The books in the library are hashed to a unique number.

Ø  Linked List.

Linked lists store item collections in a linear order. Each element in a linked list contains a data item and a link, or reference, to the subsequent item on the same list.

Ø  Stack.

Stacks store collections of items in a linear order and are used when applying the operations. For example, the order could be “first in, first out” (FIFO) or “last in, first out” (LIFO).

Ø  Queue.

Queues store item collections sequentially like stacks, but the operation order must be “first in, first out” only. Queues are linear lists.

Ø  Tree.

Trees store item collections in an abstract hierarchy. They are multilevel data structures that use nodes. The bottom nodes are called “leaf nodes,” while the topmost node is known as the “root node.” Each node has pointers that point to adjacent nodes.

Ø  Trie.

Not to be confused with a Tree, Tries are data structures that store strings like data items and are placed in a visual graph. Tries are also called keyword trees or prefix trees. Whenever you use a search engine and receive autosuggestions, you’re witnessing the trie data structure in action. subsets of another.

Why we need different data types

in programming?

In computer science, a data structure is a particular way of collecting and forming data in computer in such away so that we can operate on them efficiently. Every enterprise application uses various types of data structures in one or the other way.

Computer programs are composed of two items: Data and Operations on that Data. Because, at their heart, computers are simple devices, they can only represent very simple pieces of information.

The data types can simply be described as: int, booleans, characters, arrays, structures and so on.

In simple language, we can describe Data Structures are structures programmed to store data, ordered data, so that we can perform different operations easily. It represents the knowledge of data to be organized in memory occupation.

For example if we store data as name “Mira” and Percentage “75.5”, then record data name is string type and percentage is float type. Record stored is student name with percentage. We can also store with Roll-No (Integer).

Integral Types

• Integral data types include all whole numbers, that is numbers they don’t have any fractional component itself.

Floating Point Types

• Floating point types include all types in which a number may have a fractional component, such as 3.14 or pi.

Characters

• Most modern computer programming languages store alphabets, characters by representing each one using a small piece of numeric code.
• As we know that number of characters that must be stored is typically a large number, and the number of bits needed to represent each character by character which is unique and small.

Strings

• Most modern computer programming languages have means of representing character strings, which is collections of characters such as words or sentences etc. to performed the manipulation operation on different data as per usage.

Arrays

• Arrays which are collections of data elements all having the same data type, so the execution becomes easy performing some operation on index value.

Classes

• Classes are also similar like structures, except that in addition to data, they also contain the functions (methods) which is associated with the data.
• The classes which is a collection of related data that represents an entity also represents  methods to maintain and manipulate that data as per requirement.

TCCI provides best teaching in various programming courses through different learning method/media as student’s convenience.

How to start Learning a Coding?

Coding means interaction with the computers just let them know What to do, How to do, When to do and Why to do. We can say that it’s a procedure of planning and making executable programs to perform a particular task.

Essential steps to start learning a Coding

1. Fundamental of Coding

As stated above coding is to deal with the machines tell them What, How, When and Where   to do any task to obtain the results.

Which include following aspects:-

Syntax: – When we communicate in our regional language we follow some syntax in a same way while learning coding we have to follow some rules.

Data Types:- While practicing the code you have to declare the type of data it’s a method which tells a computer how to interpret the data in a proper format.

Variables:- It’s aterm which used to store some valuable information in a form of data. Without variable you can’t start coding practise.

Control Structures:- Its technique which used to define the control of your coding in a program in which direction your program will executes to generate the favourable output.    A control structure is considered blocks also which analyse the variables and coding statement which is based on given parameter. The controlling techniques are decided the flow, control and logic of any program while executing the code. Without use of controlling structure sometime it’s difficult to understand the flow of programming.

For Example:-

Consider this coding scenario

a=10, b=20

If(a==b)

           display resulta()

else

           display resultb()

Looping:- It’s a repetitive task which will save your precious time while executing a program. Many a times you need to perform heavy task at that time looping is a best technique to solve the heavy task by saving your precious time.       

2. Why you want to Code

Before you start coding, ask why you want to code. Start practicing the coding from baby steps never takes a jump into the coding practice. By learning coding will help you to understand the critical problem in very simple steps but it also benefit to abstract thinking in a proper way.         

3. Select our language

While starting a coding practise chooses a language which will easy for you to know the coding though you are belongs to Non-IT field. If your domain is Non-IT in such scenario  HTML is a very easy and simple web based scripting language to start coding from the ground level.

4. Book Reading        

Pick a book of your favourite programing language while reading the books you will become more and more familiar with the coding scenario and structure. You will also come to know that while reading a book that helps you to solve your doubts and queries in very precise way. Good books, good tutorials provide best opportunities to understand the code in a good way. By reading programming books will help you to focus the code as compare to watching programming videos. If you are trying to learn programming by watching videos you will remember the video for some particular time but if you have a sound habit of reading programing books that will give you clear cut idea about programming.          

5. Data Structures

It’s a practice which used to shape the data in proper way to store, organize and retrieve in a computer to perform any operations as and when required.

Data structures are divide into two parts ie. Linear and Non-Linear

Linear- A structure where the all the element of data is arranged one by one in a proper sequence.    

Non Linear- In non-linear data structures all the data are arranged in array which are having the same data type.    

Data Structure is so much useful for data manipulating i.e. Insert, Update, Delete, Search and Sort.

6. Algorithm  

It is a step by step technique to know the flow of any program which is in sequential format while apply into coding. With the use of algorithm you can break the problem into smaller pieces though it becomes easier to know the flow of any program. 

Let us understand the algorithm via simple example:-

Step 1: Start

Step 2: Declare three variables a, b, c

Step 3: Assign value to variable a=10, b=20

Step 4: Process Adding operation on variable c=a + b

Step 5: Display the result c=30

Step 6: Stop

7. Pseudocode

It is very similar to algorithm but slightly different i.e. it uses the English format. Pseudocode is nothing but a stage by stage technique that helps us to record the code into programing language. 

Pseudocode is nothing but a blue print of code which will identify the different approaches, strategies, and the flow of structure also the actual interface of program.

10 Tips to become a Good Programmer

Programming is a sequence of code to be executed on machine in a systematic way to perform any task.

Programming is the procedure of execution a task in calculation, with the help of designing and building an executable computer code which involves such as Define the Problem, Analyse the Problem, Algorithm Development, Documentation, Testing, Debugging and maintenance of code on a regular basis.

10 Tips to become a Good Programmer

1. Know Your Problem

First of all to become a good program try to understand the base of problem.Try not just understand the problem, but understand in such a way that you can solve the problem.

2. Construct Calm Answer

Coding is good, but it’s only a tool for problem solving. Many a times we get frustrated while solving the problem but frustration is not only the solution to be a problem solver. Try to calm down yourself it’s the only way to be sound programmer.     

3. Be Flexible

As a programmer you should have a good sense of what changes is coming in the future, meanwhile prepare for these changes. The main advantage of flexible code is that it allows us to implement changes faster, and also fix bugs faster. If we couple things just right, then fixing a bug in one place will fix it everywhere.

4. Simplicity of Code

Make your program very simple and precise. If any other programmer figures out your code they are able to read and execute your code. Best way to be a good programmer is giving comment line after every certain line of code wherever required.

5. Updating of Code

Whenever you are trying to learn programming keep in mind that you have to update yourself on a regular basis that is only way to become the good programmer.     

6. Quality Maintenance

While developing a program makes sure you maintain the code quality because writing multiline of code in a program in useless if your code generating bugs and bugs. So make a habit write few codes but that should be execute effectively in a program by creating less bugs.

7. Testing of Code       

Whenever you start the programming you will face a lot of problems, you get stuck there, you will be asked to implement the code practically and find the solution for a specific problem and there you will scratch your head while implementing the code.

To be good a programmer, testing code is equally important as producing code. As a programmer you are responsible for testing your code. Without testing of code programming is not possible.

When you write the code, play with the code, change your code to see different results optimize the code and try different solutions, your logical thinking ability get improves day by day and you eventually learn a lot of things that make you a better programmer.

When you start coding, practice the same code or sample again and again until or unless you don’t need to refer to the same book or resource from where you have learned

8. Use Working Resources

There is plenty of working online resources are available which are paid or unpaid. You can take help from these online resources and start your programming journey. You can subscribe to YouTube channels or try coding boot camps to learn programming quickly and effectively.

9. Debug of Code

Making mistakes in coding is very common and it’s completely acceptable in programming. You will find a lot of errors in your code at the beginning so it’s good to use debuggers to find out errors, impacts on your result and check where you have made the mistake.

No matter how experienced, you might overlook some things. A review helps in catching bugs early. You can learn better ways of doing things. It also helps in enforcing coding guidelines. You tend to code better if someone is watching.

10. Read Blogs

Some blogs also helps you understand deeper concepts of a language, operating system, framework, sourcing information from several other sources or own experiences. Thus, saving your time.

It is really helpful is finding a community to support you as you start writing code. This community will be valuable because other people will be try to engage with you in the same place as per you requirement.

One of the main things to learn programming is how to research your questions or to learn new features of your language or library with the support of using Google. Try to learn new aspects of programming daily it’s the only way keep you motivated and enthusiastic.
