just a fuction problem

How can i make "Display" fuction work?
thanks

Code:

---

#include <stdio.h>
#include<string.h>
#include<stdlib.h>

//********* prototype******//
void Display();
struct info
      {
          int test;
      };
//*********M a i n **********/
void main()
{
        struct info inf;
        printf("Enter number :");
        scanf("%d",&inf.test);
        Display(inf.test);
        //printf("\n show: %d",inf.test);
        }
//*******Function**************//
void Display()
{
        struct info in;
        printf("\n show: %d",in.test);
}

Thanks

It should be int main () instead of void main (). You forget to pass the structure to the function. Didn't your compiler give a warning/error about it?

Code:

---

void Display (struct info in);

int main (void)
{
    ...
    Display (in);

    return 0;
}

void Display (struct info in)
{
    printf("\n show: %d",in.test);
}

Probably not

It may have looked like a prototype, but it isn't really. It's just an old-style forward declaration.

void Display();
really means in C
void Display(...);

So all you can tell from this is that Display is a function - and that's it. You can pass any number of any parameters to it, and the compiler will say absolutely nothing about the correctness (or lack of).
