Why do we use functions in programming?

Question

- Break down our program into smaller parts

- Avoid repeating code

- Make our program more readable

- All of the above

Answer 1

The correct answer is "All of the above."

Functions are used in programming for several important reasons:

1. Break down our program into smaller parts: Functions allow developers to divide complex problems into smaller, more manageable pieces, making it easier to understand and maintain the code.

2. Avoid repeating code: Functions enable code reuse, which helps to eliminate redundancy. Instead of writing the same code multiple times, you can write it once in a function and call that function whenever needed.

3. Make our program more readable: Functions can encapsulate logic and provide meaningful names, which can enhance code clarity and readability. This helps other programmers (and your future self) understand the purpose of different parts of the code more easily.

Thus, functions serve multiple key purposes that contribute to better programming practices.
