Question
Is the following statement correct (YES/NO)? Justify your answer.In Scheme, when we do not permit re-assignments, the variables are in fact constants.(2 marks)
Solution
YES, the statement is correct. In Scheme, when re-assignments are not permitted, the variables do indeed behave like constants. This is because once a value is assigned to a variable, it cannot be changed. This is a characteristic of functional programming languages like Scheme, where data is immutable. Therefore, without the ability to re-assign, a variable's value remains constant throughout its scope.
