Solution

1. _out_of_time, payRate, and timeOfDay are syntactically correct variables

try-it has a special character
2beornot2be starts with a number
const is reserved

2. sequential

3. selection, repetition, function call

4. int(x)/	                   5
   x / n                       5.875
   float (n * m)                12.0 
   float(n) / m + y             8.53
   double(n / m)                 1.0
   (int)x % m                      2

5. A compiler translates from a high level language into machine language.
 
6. one

7. z / a * b - 2 * w * -y        -14
   -y * w / z - a                 -2
   -(z / b) + -b                   4
   -z - b                         -2
   (a * (b * w / z * a) - z)     -13
   (a * z + a + a + a * w)        22

8. a) (a * sqrt(c) + d)/(e * (u - v))
   b) fabs(a) + c * sqrt(u * v * w)

9. const int Num = 50;

10. char initial;
    string first_name;

11. first_name = "Albert";

12. The answer is#
    ________
    Abraham Lincoln
    ________
    ________
    #so, there

    # is a blank
    ______ is a blank line

13. True

14. True

15. const float E = 2.7128;

16. int total;
    float average;

18. a. someInt = int(float(5) + someFloat * float(3));
    b. someFloat = 2.5 * float(someInt) / someFloat;

18. someInt + 1

19. string addres;     // Employee's street address
                       // including apartment

20. cout << setprecision(2) << fixed << setw(12);
