I wanted to compare a string without actually defining one of them as a string, something like this,

if (string == "add")

Do I have to declare "add" as a string or is it possible to compare in a similar way?

In C++ the std::string class implements the comparison operators, so you can perform the comparison using == just as you would expect:

if (string == "add") { ... }

When used properly, operator overloading is an excellent C++ feature.
