Constant

I am 21 years old. I am majoring in Information Science and Technology at UW-Milwaukee.
This is how it looks before the code reads over: $variable and UNCHANGEABLE(constraint).
This is how it looks after the code reads over: changeable and UNCHANGEABLE(constraint).

This is one of those situations where constraints are variables, but variables are not constraints. Essentially, the concept is that you still set a constraint like you do with variables. The differenece, however, is that constraints are fixed values/parameters and variables are changeable. Constraints can be used whereever in the code, however variables can only bse used where it is set. i.e inside an if-statement
