Question 6 (6+7+7=20 points ) Consider the following program from a made up language "gameG" that uses pass-by-name parameter passing: a) (6pt) What scoping (dynamic or static) should "gameG" use? Why? In whose environment (caller or callee) who would we want the arguments to be evaluated? b) (7pt) A programmer wants to use the call exchange on existing variables s and t. Will they face any problems when calling exchange(s,t), if yes, how to solve it? c) (7pt) The same programmer tries to call exchange(i, o[i]), where o is an array. Will that be a problem? If yes, how to solve it? Will a call to exchange (o[i],i) have the same
