1 COMP122: Week 2 - Variable Assignments, Conditional Logic, and Control Structures COMP122 Week 2 Homework Complete the following problems. 1. 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); • (a) x = 5 , y = 28 , ch = '3' • (b) x = 28 , y = 36 , ch = '5' • (c) x = 5 , y = 36 , ch = 28 (undefined behavior) • (d) x = 5 , y = 28 , ch = ' \ n' 2. 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 set of statements is as follows: 13 28 D 14 E 98 A B 56 a. cin >> x >> y; cin.ignore(50, ' \ n ' ); cin >> ch; b. cin >> x; cin.ignore(50, ' \ n ' );
