Passing Values Homework Help
So far the Functions we have discussed are Void Type. These Functions just display a message. Sometimes, we pass some values to the Function as argument and it returns a value which is used by the main or any other Function.
The following example will illustrate this:
{`#include <stdio.h>
#include <conio.h>
int add(int x, int y);
int sub(int x, int y);
int mult(int x, int y);
void main()
{
//int a, b, result;
printf("Enter two integers: ");
scanf("%d %d",&a,&b);
result = add(a,b);
printf("\nThe sum of two numbers is : %d",result);
result = sub(a,b);
printf("\nThe difference of two numbers is : %d",result);
result = mult(a,b);
printf("\nThe product of two numbers is : %d",result);
getch();
}
int add(int x, int y)
{
int result ;
result = x + y ;
return result ;
}
int sub(int x, int y)
{
int result ;
result = x - y ;
return result ;
}
int mult(int x, int y)
{
int result ;
result = x * y ;<
return result ;
}`}
