Method requires more than one argument?

So, I can't compile my code like this: 

std::vector<std::string> split = split("A String Blah");

with this method signature: 

std::vector<std::string> split(const std::string& s)

because it says it requires more than one argument. Why isn't just a string enough?

When you have this line:

std::vector<std::string> split = split("A String Blah");

The C++ compiler thinks that the split referred to in the right-hand side is the same split declared on the left-hand side. As a result, it's giving you an error because, indeed, a std::vector<std::string> is not a function taking one argument.

To fix this, consider renaming the variable:

std::vector<std::string> theSplit = split("A String Blah");

Hope this helps!
