C++ Constructors Cheatsheet

Legend:

• 3️⃣ Rule of 3: if a class implements any of these 3 methods, it should implement all 3 of them. The goal is to ensure the correct management of the class member data.
• 5️⃣ Rule of 5: extension of Rule of 3. Allows for optimized usage (no copies) of the class.

0️⃣ Rule of 0: These constructors and operators are not require when you don't declare any of them and make usage of existing types that support the appropriate copy/move semantics.

It's the rule of "All or Nothing".
