Specialization: Customizing for One Type
Keep one generic print for all types, specialize it for string literals and std::string, and fix the missing include that blocks compilation.
By the end you can
- Write full specialization for const char* and std::string print
- Explain why C strings need content comparison, not address order
- Predict overload choice between generic and specialized print
01 · A question first
Generic print handles ints and doubles cleanly, but string literals print as pointers and std::string copies on every call. How do you keep the generic version for most types while giving two string forms their own behavior, and which include makes the string overload compile at all?
Make a guess before you read on.
