quick casting question

Hey, I have sort of a quick question. I have a string that is comprised of numerical values. I am lobbing off each number from the string and placing it in another array comprised of integers. How can I convert the character value from the string into the actual numerical value?

Thanks!

Hi.

Use the atol method in the stdlib.h:

http://www.cplusplus.com/reference/clibrary/cstdlib/atol.html

This page tells you how.

Question, are you using C or C++? strtol or strtod would be the function to use in C. In C++, a more preferable method may be with stringstreams.

Also, based on the title of your question (casting), I'm betting you tried to cast a string as an integer and found it to fail miserably. Remember that casting does not do any logic. It's a method of treating a variable type as another, and if you don't understand the low level implications, you are in for a world of surprise.
