Arguments and No Return Value : Types of Function Calling
Function with arguments and no Return Value :
Note :
- Function accepts argument but it does not return a value back to the calling Program .
- It is Single ( One-way) Type Communication
- Generally Output is printed in the Called function
- Here area is called function and main is calling function.
Program :
#include<stdio.h>
#include<conio.h>
//----------------------------------------
void area(float rad); // Prototype Declaration
//----------------------------------------
void main()
{
float rad;
printf("nEnter the radius : ");
scanf("%f",&rad);
area(rad);
getch();
}
//----------------------------------------
void area(float rad)
{
float ar;
ar = 3.14 * rad * rad ;
printf("Area of Circle = %f",ar);
} Output :
Enter the radius : 3 Area of Circle = 28.260000
