    getchar() and variant

    Hello,
    I need code this below but I need something like a getchar() that doens't wait for the "return" from the user. How can I implement it? (it only wait for a key pressed)
    Code:
    	int ch;
    	while ( (ch = getchar() ) != '\n') {
    	
    		cout << "ch " << ch << endl;
    	}

    You need to use system specific functions. There is no standard way to do it, but there is a FAQ on the subject "How do I get user input without waiting for Enter" or some such.
