Well in java with a string you can do this:
int stuff;
string otherstuff;
otherstuff = "I like this much stuff: " + stuff;
But in C++ I have no idea how to.
In C++11:
otherstuff = "I like this much stuff: " + std::to_string(stuff);
Historically (and still sometimes useful in C++11):
std::ostringstream ss;
ss << "I like this much stuff: " << stuff;
otherstuff = ss.str();
std::to_string. Check out related questions.
