Answers 1. The result is 3. 2. 9.0 / 5.0 * c + 32.0
3. a. someFloat = float(5 + someInt);
b. someInt = int(2.5 * float(someInt) / someFloat); 4. a. sqrt and fabs
b. math.h 5. someInt + 1 6. A value-returning function7. A void function 8. Two consecutive endl manipulators are necessary. 9. cout < setw(9) < setprecision(2) < pay;

Exam Preparation Exercises
1. Compute the value of each legal expression. Indicate whether the value is an integer or a floating point value. If the expression is not legal, explain why.
a. 10.0 / 3.0 + 5 * 2
b. 10 % 3 + 5 % 2
c. 10 / 3 + 5 / 2
d. 12.5 + (2.5 / (6.2 / 3.1))
e. -4 * (-5 + 6)
f. 13 % 5 / 3
g. (10.0 / 3.0 % 2) / 3
