Function with argument and return value
Here the calling function has the argument to pass to the called function and the
called function returned value to the calling function.
Syntax:
fun(int,int);
main()
{
int r=fun(a,b);
}
int fun(intx,inty)
{
return(exp);
}
Example:
// C code for function with arguments
// and with return value
#include <stdio.h>
#include <string.h>
int function(int, int[]);
int main()
{
int i, a = 20;
int arr[5] = { 10, 20, 30, 40, 50 };
a = function(a, &arr[0]);
printf("value of a is %d ", a);
for (i = 0; i < 5; i++)
{
printf("value of arr[%d] is %d ", i, arr[i]);
}
return 0;
}
int function(int a, int* arr)
{
int i; a = a + 20;
arr[0] = arr[0] + 50; arr[1] = arr[1] + 50;
arr[2] = arr[2] + 50; arr[3] = arr[3] + 50;
arr[4] = arr[4] + 50;
return a;
}
Output:
value of a is 40
value of arr[0] is 60
value of arr[1] is 70
value of arr[2] is 80
value of arr[3] is 90
value of arr[4] is 100
