Thread-Safe Initialization of Data
Explore thread-safe initialization methods in Modern C++ to ensure safe and efficient variable setup in multithreaded environments. Understand how to use constant expressions, std::call_once with std::once_flag, and static block scope variables to prevent data races during initialization.

If the variable is never modified there is no need for synchronization by using an expensive lock or an atomic. We must ensure that it is initialized in a thread-safe way.
There are four ways in C++ to initialize variables in a thread-safe way.
- Constant expressions.
- The function
std::call_oncein combination with the flagstd::once_flag. - A static variable with block scope.
