Splitting a C++ String

[cyberphant0m]

I was reading an article, that said I'd be able to use the before() and after() methods on a string in order to split a string... I tried it using the ever popular "Hello world" string, but my program wont compile... Here's my code and my errors.

7 C:\programs\cardgame\cardgame.cpp
no matching function for call to ` std::basic_string<char, std::char_traits<char>, std::allocator<char> >::

8 C:\programs\cardgame\cardgame.cpp
no matching function for call to ` std::basic_string<char, std::char_traits<char>, std::allocator<char> >::

Im using Dev-C++ 4.9.8.7 on Windows XP... I've tried #include'ing the string library, but that leads to the same error messages

before() and after() aren't in the standard C++ string library.

Well... this is how I'd edit your code. All I do is find the whitespace character, and then use substrings to print out what's before and after it. Should work.

I'm at work right now and don't have .NET handy... so lemme know if it gives you any grief.

Thanx for your help guys...

I tweaked pilot006's code, because it was chopping off the "o" from hello, and also made it so it wouldn't include the space in the second string...
Also, on my compiler, I don't need to include the string header... wierd, but works out for me...
My code looks like this now (i thought i'd include it here in case someone stumbled onto this thread with the same question.

Doh! Everyone may swear at their compilers... but it woulda been nice to have one then. Glad you got it working. I used to hate substring, but it's a nice rub on the belly when it comes to string morphing. Happy coding!

My goodness, those code tags rock. I tip my hat to the new version of the forum.

FYI - there's a standard C function called strtok which can split a string up based on token(s) you pass it. In the above example you'd simply pass it in a space for the token and it would return each word for you.

What works and what's correct are often not the same. If you use std::string, you should include <string>.
