In programming, what can strongly typed languages prevent?

Strongly typed languages are designed to enforce strict rules on how data types are used and integrated within the code. This means that variables must be declared with specific data types, and the language will not allow operations that would lead to inconsistencies between these types.

This characteristic of strongly typed languages helps prevent data type mismatch errors, which occur when an operation is performed on incompatible data types. For example, attempting to add an integer to a string in a strongly typed language would result in a compile-time error or exception, signaling that the operation is invalid due to the type mismatch.

By requiring that data types match appropriately during compilation or execution, strongly typed languages help enhance program reliability and maintainability, as developers can catch type-related errors early in the development process. This ensures that functions and operations within the code behave as intended, leading to fewer runtime errors and improved overall software quality.
