C Type Casting

Type Casting in C is used to convert a variable from one data type to another data type, and after type casting compiler treats the variable as of the new data type.Syntax:

(type_name) expression

Without Type Casting


#include <stdio.h>
void main ()
    int a;
    a = 15/6;
In the above C program, 15/6 alone will produce integer value as 2.

After Type Casting

#include <stdio.h>
void main ()
    float a;
    a = (float) 15/6;
After type cast is done before division to retain float value 2.500000.

It’s best practice to convert lower data type to higher data type to avoid data loss.
