Dear,

This process is also called type casting and it is user defined. Here the user can type cast the result to make it of a particular data type. Here is a C program to demonstrate explicit type casting.

#include<stdio.h>

int main()

{  double x = 1.2;

// Explicit conversion from double to int

int sum = (int)x + 1;

printf("sum = %d", sum);

return 0;

}

This is done to take advantage of certain features of type hierarchies or type representations. It helps us to compute expressions containing variables of different data types.

Hope this helps!
