Actually, the function returns a value. Maybe you want to see it, so just print the result:
#include <stdio.h>
#include <cs50.h>
int calcrectarea(int len,int wid){
return len*wid;
}
int main(){
printf("enter length here:\n");
int x; scanf("%d",&x);
printf("enter width here:\n");
int y; scanf("%d", &y);
printf("area is: %d", calcrectarea(x,y));
}
solved The function is not returning in clang
