Functions HI-TECH C GETCH
GETCH, GETCHE, UNGETCH, PUTCH
#include <conio.h> char getch(void) char getche(void) void putch(int c)
Getch() reads a single character from the console keyboard and returns it without echoing. Getche() is similar but does echo the character typed. Ungetch() will push back one character such that the next call to getch() or getche() will return that character. Putch() outputs the character c to the console screen, prepending a carriage return if the character is a newline.
