I am trying to do something like this 

#include <conio.h>
#inlcude <iostream>

void getInput(){

   //while no input is given..
     while(!_getch()){ 
     printf("no input");
     }

   //as soon as input is given ('a', '1',...)
     printf("Input detected!");
}

i want to print "no input" over and over exept for when a key is pressed(then it should print "input detected")

but with this code it does not work because it will stop at _getch() and wait for input. how can i skip this part or how can i tell the while loop there was no input?

thank you :)
