How to parse a string to an int in C++?

Question

What\'s the C++ way of parsing a string (given as char *) into an int? Robust and clear error handling is a plus (instead of returning zero).

Answer 1

The good 'old C way still works. I recommend strtol or strtoul. Between the return status and the 'endPtr', you can give good diagnostic output. It also handles multiple bases nicely.
