Casting expressions are utilized to convert one data type to another, such as transforming an integer into a string. This is especially crucial in strongly typed languages like C, {cpp}, C#, Java, Python, and others.

However, there are instances where casting expressions are not needed. These include situations like:
|
|
|
|
- casting a variable to its own type
|
|
- casting a subclass to a parent class (in the case of polymorphism)
|
|
- the programming language is capable of automatically converting the given type to another
|
|
|
|
These scenarios are considered unnecessary casting expressions. They can complicate the code and make it more difficult to understand, without offering any advantages.

As a result, it's generally advised to avoid unnecessary casting expressions. Instead, rely on the language's type system to ensure type safety and code clarity.
