Can the addition operator be overloaded in C++?
This means C++ has the ability to provide the operators with a special meaning for a data type, this ability is known as operator overloading. For example, we can overload an operator ‘+’ in a class like String so that we can concatenate two strings by just using +.
Can the addition operator be overloaded?

Why do we use assignment operator overloading in C++?
The overloading assignment operator can be used to create an object just like the copy constructor. If a new object does not have to be created before the copying occurs, the assignment operator is used, and if the object is created then the copy constructor will come into the picture.
