Thread-Safe Initialization: Constant Expressions
Explore how constant expressions defined with constexpr in C++ support thread-safe initialization at compile time. Understand the constraints on user-defined types to enable their instantiation as constant expressions, ensuring safe concurrent usage without runtime overhead.

Constant expressions are expressions that the compiler can evaluate at compile-time; they are implicitly thread-safe. Using the keyword constexpr in with a variable makes the variable a constant ...
