UGC NET CSE | December 2012 | Part 3 | Question: 48

Question

Functions defined with class name are called as

• A. Inline Function
• B. Friend Function
• C. Constructor
• D. Static Function

Answer 1

Ans: C

A constructor is different from normal functions in following ways:

• Constructor has same name as the class itself
• Constructors don’t have return type
• A constructor is automatically called when an object is created.
• If we do not specify a constructor, C++ compiler generates a default constructor for us (expects no parameters and has an empty body).

Answer 2

A member function of a class is a function that has its definition or its prototype within the class definition like any other variable. It operates on any object of the class of which it is a member, and has access to all the members of a class for that object.

Member functions can be defined within the class definition or separately using scope resolution operator, ::. Defining a member function within the class definition declares the function inline, even if you do not use the inline specifier. 

Hence,Option(A)Inline Function

@LeenSharma Sir,Inline Function is a wrong answer. Constructor is the right one. :)
