What is the main purpose of writing functions that treat objects as their base types?

  1. To speed up program execution

  2. To reuse code across different types

  3. To use less memory

  4. To improve compile-time type checking

The correct answer is: To reuse code across different types

By writing functions that treat objects as their base types, we can reuse the same code for multiple types instead of writing separate functions for each type. This saves time and effort and helps us avoid duplication of code. Option A is incorrect because treating objects as their base types does not directly impact the speed of program execution. Option C is incorrect because the memory usage is not affected by how an object is treated in a function. Option D is incorrect because compile-time type checking refers to the verification of data types in a program, which is not directly related to treating objects as their base types in functions.
