Constructor with Default values with example and code in c++ oop

Default value constructors are used to provide flexibility and convenience when creating objects. Here are some reasons why they are used:

1. Simplified Object Creation: Default value constructors allow objects to be created without explicitly providing values for all constructor parameters. This simplifies object creation, especially when some parameters have default values that are commonly used.

2. Reduced Code Duplication: By defining default values for constructor parameters, you can avoid defining multiple overloaded constructors with different parameter combinations. This reduces code duplication and makes the class definition more concise.

3. Improved Readability: Default value constructors can improve the readability of the code by making object creation more straightforward and concise. Developers can quickly understand how to create objects without needing to refer to documentation or overloaded constructor definitions.

4. Backward Compatibility: Default value constructors can be added to existing classes without breaking backward compatibility with code that relies on the previous constructor signatures. This allows for easier maintenance and evolution of the codebase.

5. Flexibility in Initialization: Default value constructors allow objects to be initialized with default values for certain parameters while still allowing customization when needed. This provides flexibility in object initialization based on specific requirements.

Overall, default value constructors offer convenience, flexibility, and improved readability in object creation, making them a useful feature in C++ programming.
