#include <conio.h>
#include <iostream>

int main()
{
	unsigned char LOL;
	while(1){
	LOL = getch();
	std::cout << (int)LOL << ' ' << LOL << '\n';
	}
	return 0;
}

As you can see by using this code, an arrow returns a specific value. You can store that value in an integer variable, and then compere that value in de condition of an if-statement

#include <conio.h>
#include <iostream>

int main()
{
	int input;
	while(1){
    input= getch();
	std::cout << input << "\n";
	if (input==72)
	std::cout<<"Up!\n";
	if (input==75)
	std::cout<<"Left!\n";
	if (input==77)
	std::cout<<"Right!\n";
	if (input==80)
	std::cout<<"Down!\n";
    }
    return 0;
}

I dont know or there is a way to do this as you're trying. You should searce the reference-part of this website for that.

by the way where did u find those numbers??? (ex:72 is up , 75 is left , 77 is right , 80 is down :S )??

By using the first code :)

(If you try it, you will see that 'up' not only returns 72, but also 224 and, depending of the kind of datatype you are storing the value in, a letter)
