Suppose you are given the following variable declarations: int x, y; char ch; What values (if any) are assigned to x, y, and ch after each of these statements execute? Assume that the input to each statement is the same: 5 28 36 a. cin >> x >> y >> ch; b. cin >> ch >> x >> y; c. cin >> x >> ch >> y; d. cin >> x >> y; cin.get(ch);
