The C++ Module 09 delves into advanced concepts of the Standard Template Library (STL) through three comprehensive exercises. It emphasizes adhering to C++98 standards while exploring Object-Oriented Programming principles.
"Bitcoin Exchange," requires creating a program to calculate Bitcoin values based on a provided database, focusing on error handling and container usage.
