Options:

Correct Answer: To verify that operations are performed on compatible data types

Solution:

Type checking verifies that operations are performed on compatible data types, ensuring program correctness.

What is the purpose of type checking in a compiler?

Step 1: Understand that a compiler is a program that translates code written in a programming language into machine code.
Step 2: Know that different types of data exist, like numbers, text, and true/false values.
Step 3: Realize that operations (like adding or comparing) need to be done on compatible data types (e.g., you can't add a number to text).
Step 4: Learn that type checking is a process where the compiler checks if the data types used in operations are compatible.
Step 5: Understand that if the types are not compatible, the compiler will raise an error to prevent incorrect operations.
Step 6: Conclude that type checking helps ensure the program runs correctly and avoids bugs.
