A program determines if a user's age is high enough to run for U.S. president. The minimum age requirement is 35. How should the item that holds the minimum age be declared?

Declaring the item that holds the minimum age requirement as a constant integer allows the program to clearly define that this value will not change throughout the execution of the program. This is particularly important in the context of the minimum age to run for president, as legal requirements are fixed and should remain consistent.

Using a constant makes the code more readable and maintainable, as it conveys the intent that this value is a defined rule and not meant to be altered. Additionally, if the requirement were to change in the future, updating a single constant value is far easier than searching through the code for every instance where the age might have been assigned to a variable.

By choosing a constant integer for the minimum age, this approach enhances code clarity and reinforces good programming practices, promoting the use of meaningful constants for fixed values in software development.
