 # include & lt; Windows. H> 
Int main () 
{
while (! GetAsyncKeyState (13))//the corresponding key yourself for ASCII 
{
Printf (" 123456789 \ n "); 
Sleep (50); 
} 

return 0; 
}

Can use multithreading, semaphore to implement;

The main thread receives input set a variable, the child thread print (infinite loop) and determine a variable;
