}I get the following 4 errors,
char input_digit[LENGTH];This is a declaration Syntax Error.
cin.getline(input_digit,LENGTH);This one is 'Undefined Symbol 'input_digit''
cin.getline(input_digit,LENGTH);This one is 'Could not find a match for 'istream::getline(undefined,const int)'
if (key_pressed == "Y" || key_pressed == 'y')and the last error is 'Cannot Convert 'Char' to 'Char *'.
I'm pretty bad at programming and I can't really understand whats wrong with the code here, I suspect its something obvious though.
Thanks in advanced,
and Hello all on DaniWeb.
