Data types in C programing 

C programing language, a data types  are often defined as a group of values with similar characteristics.


1.) Basic Data types(Primary Data type)

Primary data types also are called as Built-In data types. In below explained the type of primary data types in c programming-

i) Integer data type- 

The integer data type may be a set of whole numbers. Every integer value doesn't have the decimal value. We use the keyword "int" to reprsent integer data type in c.
In c programing "%d" is used to print the integer data type.

Q.N. Write a program to print integer data type in c language .
code input:
#include<stdio.h>
void main()
{
int a=10;  // declaration  of integer data type
printf("%d",a);
}
output;-
10
--------------------------------

ii) Floating point data type

floating-point data types are a group of numbers with the decimal value. Every floating-point value must contain  the decimal value. We use the keyword "float" to represent floating data type. Size of float data type is 4 bytes. Fromat Specifier is "%f" to print the float data type

Q.N. write a program to print float data type .
code input:
#include<stdio.h>
void main()
{
float  a=10.2;
printf("%f",a);
}
output:-
10.200000
