Converting Variables

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:

Code:

---

char c;
int x;
x = c - '0';

---

Also see isdigit().

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.
