In this post, we will understand the difference between copy constructor and assignment operator in C++.
Copy Constructor
It is an overloaded constructor.
It initializes the new object with an already existing object data/value.
It is used when a new object is created with the help of some existing object.
Both these objects would be stored in separate memory locations.
If no copy constructor is defined inside the class, the compiler provides one on its own.
Assignment Operator
It is an operator.
It assigns the value of one object to another object, where both of these objects would already exist.
It is used when it is required to assign an existing object to a new object.
There is used a single memory location to store this object.
But there are multiple reference variables used to point to this object’s location.
If this operator is not overloaded, the bitwise copy will be created.
