When we talk about how procedures and functions work in programming, it’s important to think about what you need to do.

Procedures are like helpers that just do things. They can follow a list of steps but don’t give back a result. This makes them really useful for tasks that repeat a lot or affect something else, such as:

• Data Manipulation: Procedures are great when you need to change information in a database. Here, you care more about getting things done than about getting a value back.
• Input/Output Operations: If you want to print something on the screen or read from a file, procedures do a great job. They usually don’t need to return a value to be helpful.

On the flip side, Functions are special because they always give back a value. They are best when the result is important, like in these situations:

• Calculations: If you’re figuring out something like $x^2 + y^2$, functions are perfect because they return the answer quickly, making them great for math problems.
• Data Retrieval: Functions work well when you need to get some processed data back, giving you immediate results to use in your program.

In short, whether procedures or functions are more efficient depends on what you’re trying to accomplish.

Procedures are best for doing actions and changing things, while functions are better at calculating and returning values. Both of them are important tools, and knowing when to use each one will help you become a better programmer!
