How does type checking improve code quality?

What is type checking and how does it work?

Type checking is the process of verifying the type of a variable or expression in programming. It ensures that the data types used in operations are compatible, which helps prevent errors.

How does type checking improve code quality?

Type checking improves code quality by catching type-related errors at compile time or runtime, reducing bugs and enhancing maintainability.

Can you give me an example of type checking in action?

Sure! In a statically typed language like Java, if you try to assign a string to an integer variable, the compiler will throw an error, preventing potential runtime issues.

What are the differences between static and dynamic type checking?

Static type checking occurs at compile time, while dynamic type checking happens at runtime. Static checking can catch errors earlier, while dynamic checking offers more flexibility.
