I was just wondering, what would be the best way of converting a char variable (made up of numbers only, up to three digits) into an int variable. Help appreiciated

Hint:
Also see isdigit().Code:char c; int x; x = c - '0';

A char variable can only hold a single digit. You probably mean a string (or a character array used to store a string).
Use a stringstream (as in the first FAQ linked) or boost::lexical_cast.
This http://cboard.cprogramming.com/showp...32&postcount=7 works nicely. I seem to reference this a lot
