Question 3 (9 points) Evaluate the expressions in the left column. Match your answer to the correct value in the right column. (3.4) 13.5+ 2.0 4.0 / 4.0 1. 22 25+ 4 - 7 2. 2. 42 % 36 - 6 + 36/7.4 3. 14 20 - 13 % 2 + 18/9 4. 8 5/9* (32.6 - 4.5) 5. 7.00 7. 14 28 / 4.0 8. 0 13/3. 6. 10 9. 15.5 8/3 > x assigns the value 7 to x. (6) Oh) in an output statement, the newline character may be a part of the string(10) Oi) in C++, all variables must be initialized when they are declared. (7) | 1) In a mixed expression, all the operands are converted to floatingpoint numbers. (4) k) Suppose * = 5. After the statement y = x++; executesy is 5 and x is 6. (9) Suppose a = 5. After the statement +a; executes, the value of a is still 5 because the value of the expression is not saved in another variable. (9) 0 Question 18 (9 points) Suppose a, b, and c are int variables and a = 7 and b = 2. What value is assigned to each variable after each statement executes? If a variable is undefined at a particular statement, report UND (undefined). (6,9) a = (b++) + 3; a = A , b = A .C= A/ c=2* a + (++b); a = A b = A C = b = 2 * (++c) - (a++); A a = ,b= A A/ Ouestion 19 IR neintel What is printed by the following program?
