Question

How many default constructors may a class have?

Short answer

Answer: A class can have only one default constructor.

Step-by-step solution

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.

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.

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.
