In this chapter you will learn about type casting. Type casting allows you to convert data from one type to another type.
C type casting
One data type can be converted to another data type through type casting. For type casting in C programming we use cast operator and it is expressed by (type).
C type casting syntax
(type)value;
Without type casting:
int f= 5/2;
printf("f : %d\n", f );//output: 2
Including type casting
float f=(float) 5/2;
printf("f : %f\n", f );//Output: 2.500000
Example: Use of type casting
Let’s see an example of casting an int value to a float:
#include <stdio.h>
#include <conio.h>
int main(){
clrscr();
float f= (float)5/2;
printf("f : %f\n", f );
getch();
}
When the above program is compiled and executed it will output as follows:
f : 2.500000
