Assume the following stream input and variable declarations: Stream Input (from cin): 42 75 B 19 Q 22 Declarations: int x, y; char ch; What is the result for the following statements, i.e. what values are stored in which variables after each statement is executed? Consider each part (a, b) by itself, that is, each set of instructions will be expected to interact with a fresh copy of the same stream input as given above. (a) cin >> x >> y; cin.ignore (50, ); cin >> ch; (b) cin.get (ch); cin.ignore (50, B); cin >> x >> y;
