    What is the difference between constants and read-only variables that are used in programs?

    Constants perform the same tasks as read-only variables with some differences. The differences between constants and read-only are

    Constants:

    Constants are dealt with at compile-time.

    Constants supports value-type variables.

    Constants should be used when it is very unlikely that the value will ever change.

    Read-only:

    Read-only variables are evaluated at runtime.

    Read-only variables can hold reference type variables.

    Read-only variables should be used when run-time calculation is required.
