programming question

[Kntx]

I'm programming something in C and I want the arrow keys on the keyboard to affect a variable.

How do I go about doing that???

My C skills are rusty, but I would try something like this to determine which ASCII character the arrow keys represent:

char c;

while (true) {
c = getchar();
println("You just pressed: %c.", c);
println("That is ascii: %d.", c);
}

Then, once you know what value the arrow keys return, you could do whatever you want when they are pressed. For example, if the up-arrow returned 201 (I don't know what it really returns):

while (true) {
c = charchar();
if (c == 201) {
variable++;
}
if (c == 'Q') {
// Quit
break;
}
}

This should probably go in Software. 😉
