Data Types in C with Examples

 Integer

Integer data types are used to store only numeric data that is numbers they don’t have any fractional component itself.

Example:-

#include <stdio.h>

int main()

{

int num_value = 10;              

printf("%d\n", num_value);

return 0;

}

Float

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

Example:-

#include <stdio.h>

int main()

{

float float_value = 10.55;              

printf("%d\n", float_value);

return 0;

}

Character

Most modern computer programming languages store alphabets, characters by representing each one using a small piece of numeric code.

Example:-

#include <stdio.h>

int main()

{

char char_value = 'T';             

printf("%d\n", char_value);

return 0;

}

Array

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

Example:-

#include <stdio.h>

int main()

{

int arr_value[] = {10, 20, 30, 40, 50};             

printf("%d\n", arr_value[0]);

printf("%d\n", arr_value[1]);

printf("%d\n", arr_value[2]);

printf("%d\n", arr_value[3]);

printf("%d\n", arr_value[4]);

return 0;

}
