Introduction to CppMem
This lesson gives an introduction to the case study of ongoing optimization with CppMem.
We'll cover the following...
I will start with a small program and successively improve it, then verify each step of my process with CppMem. CppMem is an interactive tool for exploring the behavior of small code snippets using the C++ memory model.
First, here is the small program.

// ongoingOptimisation.cpp#include <iostream>#include <thread>int x = 0;int y = 0;void writing(){x = 2000;y = 11;}void reading(){std::cout << "y: " << y << " ";std::cout << "x: " << x << std::endl;}int main(){std::thread thread1(writing);std::thread thread2(reading);thread1.join();thread2.join();}
The program is quite simple. It consists of the two threads thread1
