Type Casting in C

Type casting allows us to convert one data type into other. In C language, we use cast operator for type casting which is denoted by (type).

Syntax:

 
  1. (type)value;      

Note: It is always recommended to convert lower value to higher for avoiding data loss.

Without Type Casting:

 
  1. int f= 9/4;  
  2. printf(“f : %d\n”, f );//Output: 2  

With Type Casting:

 
  1. float f=(float) 9/4;  
  2. printf(“f : %f\n”, f );//Output: 2.250000  

Type Casting example

Let’s see a simple example to cast int value into float.

 
  1. #include<stdio.h>  
  2. int main(){  
  3. float f= (float)9/4;    
  4. printf(“f : %f\n”, f );    
  5. return 0;  
  6. }      

Output:

f : 2.250000
