Type Casting in C Language

Type Casting

- When user needs the type conversion explicitly, then type casting is used in c programming language.

- Remember that type conversion is automatic while type casting is explicitly specified by the programmer in      program.

- Syntax:

              (type_name) expression;

- Where, type_name is the name of data type we want to convert the expression to.

- The converted value is used during evaluation of expression only.

- It does not change the basic data type of operand(s) of an expression.

- Example:

#include<stdio.h>               

#include<conio.h>

void main()

{

              int sum = 47;

              int number = 10;

              float average;

              clrscr();

              average = sum/number;       

              printf("average = sum/number = %f",average);              

              average = (float)sum/number;

              printf("\n average = (float)sum/number = %f",average);

              

              getch();

}
