How do constants affect memory usage in programming?

How do constants affect memory usage in programming?

Constants are fixed values that do not change during program execution. They can help optimize memory usage by reducing the need for variable storage.

Can you give an example of how using constants can save memory?

Sure! If you use a constant for a value that is reused multiple times, it avoids creating multiple variable instances, thus saving memory.

Are there any downsides to using constants?

One downside is that if a constant needs to change, you must update it in the code, which can be less flexible than using variables.

How do constants compare to variables in terms of performance?

Constants can improve performance since they are often optimized by compilers, leading to faster access compared to variables.
