Introduction

• An object can be copied or moved in five different cases:
• How does assignment use a copy or move operation?
• How does the compiler optimize copy operations using Return Value Optimization (RVO)?

class Example {
    int a;
    double b;
    std::string c;
public:
    Example() = default;
};

• Write a default copy constructor for this class.
• When would we purposefully specify = default for constructor
• Why must we explicitly define copy and move operations for a class with pointers?
• What is the Rule of Zero in C++?
• How do we prevent a constructor from being generated?
• Why do we use explicit for single-parameter constructors?
• How can implicit conversion cause unexpected behavior, and how do we prevent it?
