How to make a simple c++ menu?

Question

C++ / C#

Hello :) someone fumbles help to make a similar menu in C ++


, the menu should be in the console for the program whose code is below, I do not expect a full answer, but I will be glad to help, thanks in advance)

#include <iostream>
#include <conio.h>
#include "winbgim.h"
#include <math.h>
#include <cstdlib>
#define ESC 27
#define LEFT 75
#define RIGHT 77
#define TOP 72
#define BOT 80
#define ROTX 100
#define ROTY 115
#define ROTZ 97
#define RSZP 120
#define RSZM 122

Answer 1

If the code above is yours, then I don’t understand what the problem is to make the menu.
It's just five lines of output, waiting for input, and a switch. You can wrap it all up in a loop. Well, or you did not describe the condition enough
