Module 7 More Data Types and Operators

A variable declared with the const modifier cannot have its value changed during the execution of your program. Thus, a const “variable” isn’t really variable! You can give a variable declared as const an initial value, however. For example, const int max_users = 9; creates an int variable called max_users that contains the value 9. This variable can be used in expressions like any other variable, but its value cannot be modified by your program.
