As a pr

A constant is a constant in the process of running the program. Since some constants are often used repeatedly during programming and development, and their meanings are sometimes difficult to remember, we need to check each time. If constants are defined, they will simplify them, this improves code readability and maintainability.Note: you cannot arbitrarily modify or assign new values. VB. there are two types of constants in.
