    Getting the char from kbhit()

    I need to be able to have a function that I can use like kbhit() that I can get the char out of. No getch(), please. I'm not trying to pause the program. In fact, that's exactly what I want to avoid.

    using getch with kbhit wont pause your program if you only call getch if kbhit returns true.
    Code:
    while( ! kbhit() )
    {
         // do stuff
    }
    
    ch = getch();
    
    // do other stuff
    This won't pause your program because getch will read the key which ended the loop and move on to the other stuff.

    Code:
    #include <conio.h>
    #include <iostream>
    
    using namespace std;
    
    int main( void )
    {
       char ch;
    	
       // Display message until key is pressed. 
       while( ! kbhit() )
          cout << "Hit me!! ";
    
       // get the key pressed
       ch = getch();
    
       cout << endl << "Key struck was " << ch;
    
       return 0;
    }
    Try that, took it of msvc help.

    If you want to use kbhit() / getch() actively in a game loop:
    Code:
    char Key=0;
    //Will loop until ESC is pressed
    while(Key!=27)
    {
      Key=0;
      if(kbhit()) Key=getch();
    
      //Prints text when ENTER is pressed
      if(Key==13) cout << "You pressed Enter" << endl;
    }
