Answer 1

Answer:

B. Left hand operand must be object

Answer 2

Answer:

In case of binary operator overloading with member function, both the operands must be objects.

Explanation:

In C++, we can change the way binary operators work for user-defined types like objects and structures. This is known as binary operator overloading.

For example,

• Suppose we have created three objects obj1, obj2 and obj3 from a class named Complex that represents complex numbers.

• Since operator overloading allows us to change how operators work, we can redefine how the + operator works and use it to add the complex numbers of obj1 and obj2 by writing new code.
• When we overload the binary operator for user-defined types by using the code: obj3 = obj1 + obj2; The operator function is called using the obj1 object and obj2 is passed as an argument to the user defined function.
