Help with calling function

i cant get my program to call thew function please help

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <iostream.h>
int main()
{
  int sel;
  cout<<"Menu Program 2.0\n";
  cout<<"1. Bet You Can't\n";
  cout<<"2. Two Number Calculater\n";
  cout<<"3. Optical Illusion\n";
  cout<<"4. Quit\n";
  cout<<"Select A Operation:";
  cin>>sel;
  switch(sel)
  {
  case 1:
  int BYC();
  case 2:
  int TNC();
  case 3:
  int OI();
  }
}
int BYC()
{
cout<<"hi";
system("pause");
}

---

initialize sel (ex int sel =0;)
switch statement should have break statement..
int byc() has no return value..

If u correct all that i think it should work fine..

it should be like this...

Code:

---

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <iostream.h>
int main()
{
  int sel;
  cout<<"Menu Program 2.0\n";
  cout<<"1. Bet You Can't\n";
  cout<<"2. Two Number Calculater\n";
  cout<<"3. Optical Illusion\n";
  cout<<"4. Quit\n";
  cout<<"Select A Operation:";
  cin>>sel;
  switch(sel)
  {
  case 1:
  BYC();
  break;
  case 2:
  TNC();
  break;
  case 3:
  OI();
  break;
  }

 return 0;
}
void BYC (void)
{
 cout<<"hi";
 system("pause");
}

you're problem is that you are not using value returning functions but attempting (wrongly) to call them, plus int main () is a value returning function and has to have return 0; at the end, and with system ("pause"); you need the windows headerfile to use. I suggest you go through each tutorial on this website and maybe get yourself a book. You still need to write the other functions!

fxn also needs to be prototyped before main, or written in it's entirety above main.

yeah there are alot of errors I can't even catch because the code is a little sloppy and I suggest starting over!

not that sloppy. after your fixes, the prototype/above main, and standard compliance; it should be okay. i haven't compiled it though.

thanks guy i fiqured out some error on my own and i dont need the include <windows.h>
