Concatenating strings doesn’t work as expected [closed]

by

Your code, as written, works. You’re probably trying to achieve something unrelated, but similar:

std::string c = "hello" + "world";

This doesn’t work because for C++ this seems like you’re trying to add two char pointers. Instead, you need to convert at least one of the char* literals to a std::string. Either you can do what you’ve already posted in the question (as I said, this code will work) or you do the following:

std::string c = std::string("hello") + "world";
