Does anyone know how I can input a character without enter button

Question

I am new in c++ and Im trying to program a simply game program and I dont know how to make an input without pressing enter. In the function InputHandle I used the cin >> move, but this make my code dependant of pressing enter key. I tried to use the bib curses.h and use the getch() function, but this does not work:

__fpurge(stdin);
move = getch();
putchar(move)

other solution I tried was:

WINDOW *w;

    w = initscr();
    timeout(3000);
    move = getch();
    

the terminal read without pressing enter but the map board was printed wrong.

Here i have my entire code, Thanks.

#include <iterator>
#include <memory>

#include <fstream>

//clear the terminal every turn
