Chapter 6: Problem 24

How many default constructors may a class have?

Short Answer

Expert verified
Answer: A class can have only one default constructor.

Step by step solution

01

Understand Default Constructors

A default constructor is a constructor called when an object is created without providing any arguments. It is responsible for default object initialization. An example of a default constructor would be: "ClassName() {}" for a class named ClassName.
02

Count the constructors

Since a default constructor has no arguments, this means that there can only be one version of the constructor for a class. If a class has more than one default constructor, it would create ambiguity during object initialization. Therefore, a class can only have one default constructor.
03

Conclusion

A class may have only one default constructor. If more than one default constructor is given for a class, it will result in a compilation error.

You hear someone make the following comment: "A blueprint is a design for a house. A carpenter can use the blueprint to build the house. If the carpenter wishes, he or she can build several identical houses from the same blueprint." Think of this as a metaphor for classes and objects. Does the blueprint represent a class, or does it represent an object?
