implement a simple copy constructor. why to we implement our own

Question

Accepted Answer

A copy constructor is used to create a new object with the same values as an existing object. We implement our own to ensure proper copying of data members.

A copy constructor is needed when we want to create a new object with the same values as an existing object.
If we don't implement our own copy constructor, the default copy constructor provided by the compiler may not copy data members properly.
We can implement our own copy constructor to ensure proper copying of data members, especially if the class contains pointers or dynamic memory allocation.
The copy constructor should take a reference to the object being copied and create a new object with the same values.
For example, if we have a class Person with data members name and age, we can implement a copy constructor like this: Person(const Person& other) { name = other.name; age = other.age; }
