How can I optimize string handling in C++11?

You can optimize string handling in C++11 by using std::string efficiently, avoiding unnecessary copies, and utilizing move semantics.

What are move semantics and how do they help with string optimization?

Move semantics allow resources to be transferred from one object to another without copying, which reduces overhead and improves performance.

Can you give me an example of using move semantics with strings?

Sure! Here's a simple example:

std::string createString() {
    return std::string("Hello, World!"); // Rvalue returned
}

std::string str = createString(); // Move occurs here

Are there any other tips for string optimization in C++11?

Yes! You can also use std::string::reserve() to allocate memory in advance and avoid multiple reallocations during concatenation.
