And also, you could use boost (which may be the better idea anyway versus redefining a string class):

You ever try a pink golf ball, Wally? Why, the wind shear on a pink ball alone can take the head clean off a 90 pound midget at 300 yards.

Of course, a function would be better if it's being used a lot!
Code:void MyToUpper ( std::string &MyString ) // or - std::string MyToUpperReturn() if you wanted to return it. { for ( std::string::size_type i=MyString.begin(); i!=MyString.end(); i++ ) // or - for ( int i=0; i<(int)MyString.size(); i++ ) { MyString[i] = std::toupper( MyString[i] ); } }

You can also use std::transform:
Code:#include <string> #include <iostream> #include <algorithm> int main() { std::string s("tHis iS Some SCRewy cRap"); std::transform(s.begin(), s.end(), s.begin(), toupper); std::cout << s << std::endl; std::cin.get(); }
Nice! I like this one the best, very clean! It uses the vector commands, which is coooooolOriginally Posted by anon
Thanks for this!
You do realize that transform had already been suggested twice in this thread, right?
I didn't see a thing
Alas, there was no example before!...
Probably. But had he read about transform when it was suggested without code, it wouldn't have take him 2 days to solve this problem.
No. Coding is not for the lazy.

Mkay, maybe because I'm 16, and I have other things to do besides programming? So yes, I am lazy. It's not like I get paid, like you, so please stop caring about other people, and go smoke some weed because you seem tense!
Thank you son

Hmmm, we get paid for posting on the forums!?!? Why hasn't anyone told me that?
It might not work. C++ algorithms want a function object or function with C++ linkage. That means that the function needs to support name mangling. If toupper is declared with C linkage then the algorithm might not accept it. You should wrap toupper in a function with C++ linkage or function object.Nice! I like this one the best, very clean! It uses the vector commands, which is cooooool
Sumimasen.Code:#include <cctype> #include <string> #include <iostream> #include <algorithm> // function object struct toUpper { int operator()(int ch) { return std::toupper(ch); } }; // function with C++ linkage int toLower(int ch) { return std::tolower(ch); } int main() { std::string s("tHis iS Some SCRewy cRap"); std::transform(s.begin(), s.end(), s.begin(), toUpper()); std::cout << s << std::endl; std::transform(s.begin(), s.end(), s.begin(), toLower); std::cout << s << std::endl; std::cin.get(); }
Yup, I get paid per post!
You get payed to do nothing and just wait for someone to post some code so that you decide if you like the answer or not?
Wow!
*smokes his pipe*
