Question

I am a beginner in c++ , I need to create an application to print some thing after 10 second or after pressing a key , I tried this code but it isn’t working(after pressing a key it will print “a” lot of a instead of one “a”)

int i;
while(1)
{
    i=1;

    while(!kbhit()||i<1000)
    {
        Sleep(10);
        i++;
    }

    cout<<"a";

}//while1

Can you suggest me any better way?

Thanks

The problem is you don’t take the first key which was pressed out of the buffer…

int i;
while(1)
{
    i = 0;
    while(!kbhit() && ++i<1000)
    {
        Sleep(10);
    }

    if (kbhit()) getch(); // to get the key out of the buffer, otherwise kbhit will keep getting true.
    cout<<"a";

}//while1
