I'm currently learning C++ and working with strings. I've encountered a weird problem: I have two string variables defined as follows: `std::string str1 = "example";` and `std::string str2 = "example2";`. When I try to assign `str2` to `str1` using `str1 = str2;`, I receive an error in my compiler that says "error: no viable overloaded '='" and mentions something about no known conversion from 'std::string' to 'const char *'. I'm confused because I thought these strings were of the same type. Can anyone help me figure out what's going wrong?

This type of error usually occurs when `str1` is of type `char const*` instead of `std::string`. You might want to ensure that both are indeed `std::string` types. Check to see how you're declaring them!
You probably simplified your example a bit, as what you described should compile without errors. Can you double-check what compiler you're using? It's possible you have one of the strings defined as a pointer or marked in a way that's different from what you mentioned.
Does a declared string automatically convert to a 'char const*' in some scenarios?
