A variable's value can change while the program runs; a constant's value is fixed once set

A variable always holds text, while a constant can only ever hold a number value

A constant's value can change as the program runs, but a variable's value cannot change

There is no real difference between a variable and a constant in any programming languages

A procedure always runs faster than an equivalent function does

A function returns a value to the calling code; a procedure does not

A procedure is allowed to take parameters but a function never is able to

A function can only ever be written once and can never be reused

A value that is returned back out from a function

A particular type of count-controlled loop structure

A value passed into a subprogram when it is called

A global variable that is shared across the whole program
