You want something like this?

#include <iostream>
#include <conio.h>
#include <ctime>
using namespace std;

time_t g_Time = 0;
unsigned int g_uInterval;

void SetTimeout(unsigned int uX)
{
g_uInterval = uX;
}

void Begin()
{
g_Time = time(0);
}

bool IsTimeout()
{
if( g_uInterval < difftime(time(0), g_Time) )
return true;
return false;
}

void main()
{
unsigned int uX = 20;
cout << "Press any key in " << uX << " sec.\n";
SetTimeout(20);
Begin();
while(1)
{
if(_kbhit()) {
cout << "Key pressed.\n";
break;
}
if(IsTimeout()) {
cout << "Time out.\n";
return;
}
}
getch();
}
