Topic 19 Mutable Data Objects

Topic 19 Mutable Data Objects. Section 3.3. Mutable data. Basic operations like cons, car, cdr can construct list structure and select its parts, but cannot modify. (define x (cons 'a 'b)) x --> (a . b) Primitive mutators for pairs: set-car! And set-cdr! CHANGE the list structure itself.
