4.2 Concrete Types

• What are concrete types in C++?
• Why are concrete types often used in performance-critical applications?
• How do concrete types relate to built-in types?
• What is an arithmetic type in the context of user-defined types in C++?
• Why do we often define operations (such as addition and multiplication) outside a class definition rather than as member functions?
• Why is it beneficial for simple operations like constructors and arithmetic operators to be inlined? What are the constraints of inlining?
• What are the performance trade-offs between passing an arithmetic type by value versus by reference in operator overloading?
• If a class manages dynamic memory internally, why does the Rule of Three/Five matter?
