I saw once an algorithm in C where the menu selection had a "mini navigation" if I can call it that, where I used the arrow keys to navigate the menu and enter to select the option, I was curious to know how to do that, can anyone show? Grateful!

I found a way, but it only works with two options in the menu =/
#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
#define KEY_UP 72
#define KEY_DOWN 80
#define KEY_ESC 27
#define KEY_ENTER 13
void menu_draw();
int main (int argc, char ** argv)
{
menu_draw();
return 0;
}
void menu_draw ()
{
int key = 0;
while(1)
{
system("cls");
printf("\n ******** Menu Principal ********\n");
printf(" * *\n");
printf(" * %s Opcao 1 *\n", (key == KEY_UP)? "Û": " ");
printf(" * %s Opcao 2 *\n", (key == KEY_DOWN)? "Û": " ");
printf(" * *\n");
printf(" ********************************\n");
key = getch();
if (key == KEY_ESC)
return;
}
}

Got it, you can mark as Accept when the system allows. It was looking like a new question in the answer text.

@Brumazzidb I haven’t, as I said is a curiosity =/ I haven’t found anything on the internet about it, I wonder if I need some library or something like.

Search for a C lib called "ncurses", is the only one I know that does this.
