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.
