thanks

hi again, i checked out the code but thats not what i want (well could be used in future and i can use that in my odd and even game, thanks :P) lemme explain you again

example:-

here is a menu

--> hello

i want something like that, an arrow key for navigation

RE LAST POST

example:-
--> hello
peekaboo

now i press the down key

hello
-->peekaboo

press up key it goes to hello, like that

but thats not what i want

I'm aware of that. It's only a part of what you want, the part that recognizes arrow keys. You also need to move the cursor with something like gotoxy. My apologies, I thought it was obvious that I wasn't giving you a complete solution.

its pretty tough, its got something to do with ascii keyboard

Actually, it's dead easy. Against my better judgment, since you haven't posted any code of your own, I'll give you a more complete sample.

#include <conio.h>
#include <iostream>
#include <string>
#include <vector>
#include <windows.h> 

using namespace std;

#define FOREGROUND_DEFAULT FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE
#define BACKGROUND_DEFAULT 0
#define BACKGROUND_HIGHLIGHT BACKGROUND_BLUE | BACKGROUND_INTENSITY

/* System dependent key codes */
enum
{
    KEY_ESC     = 27,
    ARROW_UP    = 256 + 72,
    ARROW_DOWN  = 256 + 80,
    ARROW_LEFT  = 256 + 75,
    ARROW_RIGHT = 256 + 77
};

static int get_code()
{
    int ch = getch();

    if (ch == 0 || ch == 224)
    {
        ch = 256 + getch();
    }

    return ch;
}

void gotoxy(int x, int y)
{
    COORD coord = {x, y};
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
}

void show_option(const string& option, bool highlighted)
{
    if (highlighted)
    {
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_DEFAULT | BACKGROUND_HIGHLIGHT);
    }
    else
    {
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_DEFAULT | BACKGROUND_DEFAULT);
    }

    cout << option << '\n';
}

int main()
{
    vector<string> options;
    int ch, pos = 0;

    options.push_back("1) Option 1");
    options.push_back("2) Option 2");
    options.push_back("3) Option 3");
    options.push_back("4) Option 4");

    for (int i = 0; i < options.size(); i++)
    {
        show_option(options[i], i == pos);
    }

    gotoxy(pos, 0);

    while ((ch = get_code() ) != KEY_ESC)
    {
        switch (ch) {
        case ARROW_UP:
            if (pos > 0)
            {
                show_option(options[pos], false);
                gotoxy(0, --pos);
                show_option(options[pos], true);
                gotoxy(0, pos);
            }

            break;
        case ARROW_DOWN:
            if (pos < options.size() - 1)
            {
                show_option(options[pos], false);
                gotoxy(0, ++pos);
                show_option(options[pos], true);
                gotoxy(0, pos);
            }

            break;
        }
    }

    SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_DEFAULT | BACKGROUND_DEFAULT);
}
