Question

Correct syntax to access the static member functions from the main() function is ______________

(a) classObject::functionName();

(b) className::functionName();

(c) className:classObject:functionName();

(d) className.classObject:functionName();

The question was asked in a national level competition.

I want to ask this question from Types of Member Functions topic in chapter Member Functions & its Types of Object Oriented Programming

Answer 1

Right choice is (b) className::functionName();

Easy explanation - The syntax in option b must be followed in order to call the static functions directly from the main() function. That is a predefined syntax. Scope resolution helps to spot the correct function in the correct class.
