Conio.h is non-standard and deprecated:
https://en.wikipedia.org/wiki/Conio.h
Most modern compilers do not support it, and you should not use it.

Global variables are bad practice - try to modify your program to not use them.

Your indentation is abnormal try fixing it so the code reads better.

@LB if not use conio.h , how to use getch(); function ?
ne555 (10692)
if you want to read a character you may std::cin>>a_variable_of_type_char;
If you don't want buffer or echo, try curses.
