Answer the following statements true (T) or false (F)

Question

1. A constructor is a special kind of member function. It is automatically called when
an object of that class is declared.
2. A constructor is always named construct with class name attached. If the class is
Foo, then the constructor name is constructFoo.
3. A constructor is like a function. It can return any type value needed.
4. A constructor usually terminates by falling off the end of its block, but a return
statement is permitted if there is no argument add following the word return..
5. You can write a class that is useful with all its constructors in the private section.

Answer 1

1. True
The purpose of a constructor is to automatically do any needed
initialization.
2. False
The name of the constructor is just the name of the class.
3. False.
A constructor may not return any value, not even void. There can be no
return type in front of the name.
4. True
Since a constructor may need to terminate prior to falling off then end,
and may need a return statement. However, a constructor cannot return any value
whatsoever, so the return can not have an argument.
5. False
Apart from friend of the class (something you will see later in this
course) a class with all private constructors cannot create an object of the class. It
seems useless to have a class for which you can have no objects..
