Convert a String In C++ To Upper Case

Question

How could one convert a string to upper case. The examples I have found from googling only have to deal with chars.

Answer 1

Without using any libraries:

std::string YourClass::Uppercase(const std::string & Text)
{
    std::string UppperCaseString;
    UppperCaseString.reserve(Text.size());
    for (std::string::const_iterator it=Text.begin(); it(0x20)) : *it);
    }
    return UppperCaseString;
}
