What is the difference between constants and variables in C#?

In C#, constants are immutable values that cannot be changed after they are declared, while variables can be modified.

Can you give me an example of each?

Sure! A constant can be declared like this: const int maxScore = 100;. A variable can be declared like this: int currentScore = 0;.

Why would I use a constant instead of a variable?

Constants provide clarity and prevent accidental changes to values that should remain fixed, improving code reliability.

Are there any performance differences between using constants and variables?

Generally, constants can be optimized by the compiler, potentially leading to better performance, especially in large applications.
