    You need to look into multithreading. What OS/compiler are you using?

    multi-threading or multi-process solutions. Its OS and sometimes compiler specific so we'll need more info before helping you.

    Dang foiled again by XSquared.

    Why do you think that your program needs multithreading?

    @XSquared: Mainly today
    @Chobo: Like all things learning the basics of programming is the hardest part. Multithreading and multiprocess solutions are not a giant step in difficultly once you have those skills. Be patient and you'll get it

    If you are a novice in C++, I doubt the program you're making would benifit from threading. There are cases where threads can lower the performance of the program, and you can create serious issues if you do not have experiance with them. Just learn as much as you can first, then decide to use them later.
    Do not make direct eye contact with me.

    ok -.- i just wanted to add special feature to my program
    Code:
    #include <windows.h> 
    #include <iostream>
    #include <conio.h>
    
    using namespace std;
    
    void gotoxy(int x, int y)
    {
      COORD coord;
      coord.X = x;
      coord.Y = y;
      SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
    }
    
    int main()
    {
        int count;
        int i, ii;
        gotoxy(3,0);
        cout << ":";
        for (ii = 20; ii >= 0; ii--) {
            if (ii >= 10) {
                gotoxy(1,0);
                cout << ii;
            }
            else {
                gotoxy(1,0);
                cout << " ";
                gotoxy(2,0);
                cout << ii;
            }
            for (i = 60; i >= 0; i--) {
               if (i >= 10) {    
                   gotoxy(4,0);
                   cout << i;
                  Sleep(50);
              }
              else {
                  gotoxy(4,0);
                 cout << "0";
                 gotoxy(5,0);
                  cout << i;
                  Sleep(50);
               }
            }
        }
        getch();
        return 0;
    }
    this program just basically counts down from 20:00 to 0:00. but wat if i want the program to accept an input from the user without interupting the count down? if i use cin, it would stop the count down until the input has been received.

    lookup kbhit(), it will tell you when the user hits a key and using getche() you can read it in one by one.
