conversion from string to char

How do I convert a c++ string into a unsigned char?
Thanks

edit:

It is probably not the best method, but if you are pretty sure that you're string contains a correct char, you can do the following:

1. Get the c_str.
2. Use atoi().
3. Make a cast.

You can't generally convert a string to a char... A typical string is a string-of-characters, and won't fit into one type-char variable.

If your string is only one character long, you can "extract" that character.

Or, you can make a char equal to any one of the characters in a string.

Or, you can make a character string (AKA C-style string, or array of characters) that is equal to your C++ string.

Sorry I don't have any examples for you... No books or compiler with me... I might screw it up. :(

Code:

---

unsigned char ch = accumulate(s.begin(), s.end(), 0) % numeric_limits<unsigned char>::max();

I'll leave it up to you to figure out if this particular solution is useful or not. :)
