Data Types in C++ –

In computer science and computer programming, a data type is a grouping of data through which the compiler or interpreter can know how the developer expects to utilize the data. Most programming languages support various types of data, for example:

12 , 67.90, ‘c’, “hello!! Tom”

As a human being we can differentiate all values are different, but machine
can’t differentiate. So, we have to inform compiler which type data is
being used.

There are main 3 categories in

C++ Language 

1. Built in Types:

· void – valueless special purpose type which we will examine closely in
later sections.

  • int – integer: a whole number.

o i.e. 45,6789

· float – floating point value: a number with a fractional part.

o i.e. 56.89

  • char – a single character.

Four types data there are:

a) small a to z

b) capital A to Z

c) 0 to 9 digit

d) other symbols like tab, space,*,>,?,$ etc.

i.e ‘x’, ‘c’, ‘1’,’*’,’#’ etc.

2. User Defined Types:

  • Structure
  • Union
  • Enum
  • Class

3. Derived Types:

  • Array
  • Function
  • Pointer

DBMS Language –

Database is actually a place where related piece of information is stored and various operations can be performed on it. A DBMS is software that allows creation, definition and manipulation of database. DBMS is actually a tool used to perform any kind of operation on data in database. DBMS also provides protection and security to database. It maintains data consistency in case of multiple users.
