How do you write an assignment operator?
The left side operand of the assignment operator is a variable and right side operand of the assignment operator is a value. The value on the right side must be of the same data-type of the variable on the left side otherwise the compiler will raise an error.
What is copy constructor explain with example?
The copy constructor is a constructor which creates an object by initializing it with an object of the same class, which has been created previously. The copy constructor is used to − Initialize one object from another of the same type. Copy an object to pass it as an argument to a function.
When a copy constructor is called?

How many assignment operators are there?
There are two kinds of assignment operations: simple assignment, in which the value of the second operand is stored in the object specified by the first operand. compound assignment, in which an arithmetic, shift, or bitwise operation is performed before storing the result.
