Final answer:
A named constant is not the same as a variable and cannot be changed during a program's execution.
Step-by-step explanation:
A named constant is not the same as a variable. While a variable can change its value during a program's execution, a named constant cannot be changed. Once a value is assigned to a named constant, it cannot be modified throughout the program.
For example, if you declare a named constant called PI with a value of 3.14, you cannot change the value of PI later in the program. It will always be 3.14.
Therefore, the statement 'a named constant can change any time during a program's execution' is false.
A named constant is a variable that is set to a value that was intended not to be changed throughout the program's execution. The statement that a named constant can change any time during a program's execution is false. Once a constant is defined in most programming languages, its value remains the same and any attempt to change it will result in a compile-time error.
