DATA TYPE

DATA TYPE:

  In Computer Programming Compiler like C , C++  and Dev C++ we used different type value and variable are use such as any name, sentence, figure and numbers data type specifies what type of data variable or object can hold in computer program to create program.

  There are three main data types for beginners which are,

          1.      Integer data type

          2.      Floating point data type

          3.     Character data type

INTEGER DATA TYPE:

  The type of data which enclose the whole number numeric. For example 1, 23, 234, 644, etc. it declare by ‘int’.

Syntax = int variable 1, variable 2;

                long int variable 1, variable 2;

 int occupy one bytes means 8 bit in memory and long int occupy 2 bytes in memory

FLOATING POINT DATA TYPE:

  Another data type which consist the decimal number or numeric. For example 1.22, 45.77, 987.348 etc. are comes into float type. It declares by ‘float’.

Syntax= float variable 1, variable 2;

            double float variable 1, variable 2;

float occupy 4 bytes and 8 bytes in memory.

CHARACTER DATA TYPE:

 Character data type consist of only a character comes in this category which may be a number a character encoding text, it write like ‘a’, ‘1’, ‘9’, ‘n’ etc. it declare by ‘char’.

Syntax= char variable 1, variable 2;

Char occupy only a byte in memory when it declares.
