Description: A default constructor is a type of constructor in programming that takes no parameters when invoked. This type of constructor is fundamental in object creation, as it allows initializing an instance of a class with default values. In many object-oriented programming languages, such as Java, C++, and Python, if a constructor is not explicitly defined, the compiler or interpreter automatically provides a default constructor. This constructor initializes the object’s attributes with default values, such as zero for numbers, false for booleans, and null for references. The existence of a default constructor facilitates the creation of objects without the need to specify initial values, which can be useful in situations where basic initialization is desired or when values will be set later. Additionally, it allows the creation of collections of objects without requiring additional information at the time of creation. In summary, the default constructor is a key feature in object-oriented programming that simplifies class instantiation and improves code readability and maintainability.
