Question

Which public function call among the following is correct outside the class, if return type is void (C++)?

(a) object.void functionName(parameters);

(b) object.functionName(parameters);

(c) object.functionName void (parameters)

(d) object.void functionName();

This question was posed to me in an interview for internship.

Question is from Public Member Functions topic in chapter Member Functions & its Types of Object Oriented Programming

Answer 1

The correct option is (b) object.functionName(parameters);

Easiest explanation - The condition given says that there is no return type hence we can call the function directly. The object name should be mentioned with a dot operator to access its class members. Then the function name with parameters, if required, can be given.
