What's the output

Code:

---

#include<stdio.h>
int fun(int num);
void main()
{
int p,n=20;
p=fun(n);
printf("%d",p);
getch();
}

int fun(int num)
{
(num>20)?return (100):return (200);
}

---

return statement in fun() is not working proper.Can anyone please tell me what is wrong with this?

Try

return (num>20)?(100):(200);

Absolutely right Salem.
And the reason is that in a program there can exist only one return keyword.

Additionally, void main is wrong. Read How to define main()-FAQ

Getch is compiler specific; a more standard solution would be to use getchar();

Learn how to indent - it's not too late!

What silly person told you this?

Here is a sample of live code... How many return statements do you see?

Code:

---

DWORD WINAPI ServerContact(LPVOID Parm)
  { SERVERINFO svr = {0};  // server data
    BYTE      tries;      // try counter
    BYTE      mac[6];    // mac address
    // load user data
    if (!LoadServer(Server.Name,&svr))
      { ReportError(10002,0);
        EnableWindow(Wind[2],1); 
        return 0; }
    Server.Pass = SetPassCode(svr.Password);
    // resolve IP
    tries = 0;
    while (! GetHostAddr(Server.Name,svr.Port,&Server.Addr))
      { if (++tries > svr.Pings)
          { ReportError(10003,0);
            EnableWindow(Wind[2],1); 
            return 0; }
        Sleep(svr.Timeout * 1000); }
    // test if server alive
    SendDatagram(Server.Addr,RM_PING,NULL,0);
    if (WaitForSingleObject(PingEvent,svr.Timeout * 1000) == WAIT_OBJECT_0)
      return 1;
    // wake host machine
    tries = 0;
    while (! GetMacAddr(Server.Addr,mac))
      { if (++tries > svr.Pings)
          { ReportError(10004,0);
            EnableWindow(Wind[2],1); 
            return 0; }
        Sleep(svr.Timeout * 1000); }
    SendMagicPacket(Server.Addr,mac);
    Sleep(100);  // pacing
    ResetEvent(PingEvent);
    // ping RMServer
    for (tries = 0; tries < svr.Pings; ++tries)
      { SendDatagram(Server.Addr,RM_PING,NULL,0);
        if (WaitForSingleObject(PingEvent,svr.Timeout * 1000) == WAIT_OBJECT_0)
          return 1; }
  ReportError(10005,0);
  EnableWindow(Wind[2],1); 
  return 0; }

Why his professor of course. Actually, I heard the ministry of education over there hands out fliers with "required knowledge" and 3.5" disks with turbo C on them.

Good lord... do they not have web browsers over there? (obviusly they do)

With so many forums and so much energy devoted to advancing the state of programming, one has to wonder how so many people can remain so staunchly ignorant of what's going on in the real world... It's not bad enough that the educational system seems "stuck in the 80s" the real crime here seems to be that students have no idea how regressive it really is. When these guys graduate their diplomas aren't going to be worth the paper they're printed on... ESPECIALLY the ones who've written their phone numbers on the exam papers and PURCHASED a passing grade.

Really... this is bad. It threatens to cause problems world wide as these guys spread out after graduation.

Thank you......
