Headers / CPP Files

In C++, organizing code effectively involves splitting programs into header and source files. Header files (with extensions like .h or .hpp) declare interfaces such as classes, functions, and variables, acting as blueprints for other parts of the code. Source files (with the .cpp extension) then implement the functionality declared in the headers. This separation supports modularity, reduces compilation times through separate compilation, and enhances code readability and maintainability by clearly defining interfaces and implementations.
