a) What is the difference between formal and actual parameters of a subprogram (7 points). b) Define shallow and deep binding for referencing environments of subprograms that have been passed as parameters? (8 points) c) Consider the following skeletal program function subX() { var x; function subY() { output(x); } i) ii) function subZ() { var x; x = 3; subD(suby); } function subT(subx) ( var x x = 4; subx(); } x=1 subZ(); } what is the referencing environment of suby when it is called in subT, assuming that : deep binding is used? (5 points) ad hoc binding is used?
