When a compiler can automatically generate a constructor if it is not defined then why is it considered that writing constructors for a class is a good practice ?

Writing constructors for a class is considered a good practice for the following reasons:

1. Control over object creation — By writing our own constructors, we can control how objects of our class are created and initialised. It ensures initialising member variables to specific values and executing certain initialisation logic before the object is used.
2. Parameter validation — We can prevent runtime errors and bugs by validating input parameters and ensuring only valid objects are created.
3. Flexibility — Multiple constructors allows users of the class to create objects in different ways, depending on their needs. This makes the class more flexible and easier to use.
