Complete Modern C++ - how copy elision works

The video tutorial explains the concept of copy elision, a compiler optimization technique that eliminates temporary objects. It demonstrates how Visual Studio and GCC handle copy elision differently, using code examples to illustrate the process. The tutorial covers parameterized constructors, move constructors, and return value optimization, highlighting the importance of these concepts in efficient code execution. The video concludes with a discussion on named return value optimization and changes in C++17.

How can copy elision be turned off in GCC, and what effect does this have?
