C++: Const vs Regular Arrays

What is the difference between const arrays and regular arrays in C++?

In C++, a regular array can be modified after its declaration, while a const array cannot be changed once initialized.

Can you give me an example of how to declare both types of arrays?

Sure! A regular array can be declared like this: int arr[5];. A const array would be: const int constArr[5] = {1, 2, 3, 4, 5};.

What happens if I try to modify a const array?

If you try to modify a const array, the compiler will throw an error, preventing you from changing its values.

Are there any performance differences between using const and regular arrays?

Generally, there are no significant performance differences, but using const can help the compiler optimize your code.
