When should I use regular variables in programming?

When should I use regular variables in programming?

Regular variables are best used for storing data that doesn't need to be shared across different parts of your program.

Can you give me an example of when to use them?

Sure! If you're calculating a total price in a shopping cart, you can use a regular variable to store the subtotal.

What about global variables? When should I use those instead?

Global variables are useful when you need to access the same data across multiple functions or files, but they can lead to issues if not managed carefully.

Are there any downsides to using regular variables?

Yes, if you declare too many variables or use them inefficiently, it can lead to memory issues or make your code harder to read.
