C++ Reverse a String
Today we will learn how to reverse a string. For example, how to convert "abc123" to "321cba".
The only complicated part about this is the -1 behind length(). Without this we would get access violation errors, so let's make sure this won't happen:
std::string reverse(std::string& s)
for (unsigned int i = 0; i < s.length(); ++i)
result += s.at( s.length()-1 -i );
std::cout<<reverse("ABC"); // will give CBA
It's very simple and it works great.
A simple function, yet a very important part of our library. It will be needed in most of the games, and we will be happy to already have it implemented when it comes to that point.
