When should I use variables instead of constants?

When should I use variables instead of constants?

You should use variables when the value can change during program execution, while constants are fixed.

Can you give me an example of when to use a variable?

Sure! If you're storing a user's score in a game, use a variable since it changes as the game progresses.

What about constants? When are they useful?

Constants are useful for values that remain the same, like the value of pi or a maximum score limit.

Is it bad practice to use variables for values that don't change?

Yes, it can lead to confusion and bugs. It's best to use constants for values that should remain unchanged.
