Type Casting in C

Typecasting in the C language generally permits the users to convert one data type into other data type. For the purpose of typecasting in the C language, Cast operators are used that is denoted by (type).

Here is the syntax of typecasting in the C language:

(type)value;

Point to be noted: Converting the lower value to higher in order to avoid data loss is always recommended in the C language.

Here are two examples for you to understand the use of typecasting in the C language:
1. The following example is without typecasting:

int f= 9/4;  
printf("f : %d\n", f );//Output: 2  

2. The following example is with typecasting

float f=(float) 9/4;  
printf("f : %f\n", f );//Output: 2.250000  

Here is an example of the typecasting in the C language for a better understanding:

In the following example, it is depicted that how typecasting cast the int value into the float value:

#include<stdio.h>  
int main()
{  
float f= (float)15/4;    
printf("f : %f\n", f );    
return 0;  
}      
Output :
f : 3.750000

Here is another example of the typecasting:

#include<stdio.h>  
int main()
{  
int x= (int)15/4;    
printf("x : %x\n", x );    
return 0;  
}      
Output :
x : 3
