Is it efficient to return a string by value in STD?

Since the std::string class has the move constructor, returning even the long strings by value is efficient. If an object has a move constructor, it’s said to be characterized with move-semantics. Move-semantics imply that the object is not copied to a different location on function return, thus, providing faster function execution time.

When to use return keyword in C-C?

If a function is defined as void it does not need to return a value. Such functions return control automatically when they reach the end of their body. Still, we can use return; to end their execution from any point of their body. Here we use the return keyword to interrupt the function printIfFound.
