Extremely confused, switch bug

closed account 3R5fjE8b (226)
Alright so this whole function works fine unless an E is put through the switch statement. It will print out a blank line, then ask for input again. If you put in the E again, it works fine. It ONLY does it for THIS letter. Every other letter works like a charm. Am i missing something obvious?

Can we see get_description()? That's most likely where the problem is.

Also, line 38 is suspicious.

directions are enumerated, 0 north 1 east 2 south 3 west
exitDescription is array with the appropriate string descriptions in [0][1][2][3]

std::string cboardtile::get_description(int direction)
{
    return exitDescription[direction];
}


line 38 was a mistake, i just fixed it but same error with E passing through
