Question text
if operator+ is supported by a class, how many parameters should it be defined to accept?
select one:
a. 1 or 2
b. 2
c. 3
d. 1
e. none

b. 2

Explanation:

As we know operator + is supported by the class.Since we know that the + operator binary operator means it needs two operands to work upon it cannot work on one operand.++ operator is unary operator it works on one operand only.

For example:-

a+b

a++.

Hence we conclude that the answer is 2.
