This lab will serve as a review for the midterm.  It will involve a
collection of short answer, code error correction, and small
functions.

1. If a programming language does not use short-circuit
   evaluation, what is the output of the following code
   fragment if the value of myInt is 0?

   int other=3, myInt;
   if(myInt !=0 && other % myInt !=0)
        cout << "other is odd\n";
   else
        cout << "other is even\n";

2. if x is 0, what is the value of (!x ==0)?

3. Which of the following are equivalent to (!(x<15 && y>=3))?
   a. (x>15 && y<=3)
   b. (x>=15 && y < 3)
   c. (x>=15 || y < 3)
   d. (x>15 || y < 3)
   e. C and D

4. What is wrong with the following switch statement?

   int ans;
   cout <<"Type y for yes on n for no\n";
   cin >> ans;
   switch (ans){
     case 'y': 
     case 'Y': cout << "You said yes" << endl; break;
     case 'n':
     case 'N': cout << "You said no" << endl; break;
     default: cout << "invalid answer" << endl;
   }

5. A ___________ is a main program that only checks that functions
   execute correctly

6. When the address of the actual argument is passed to the formal
   parameter, this is called __________________________

7. What symbol is used to signify that a parameter is a reference
    parameter? ______

8.  What is the output of the following function and function call?

    void calculateCost(int count, float& subTotal, float& taxCost);

    //begin fragment
    float tax = 0.0, subTotal = 0.0;

    calculateCost(15, subTotal,tax);
    cout << "The cost for 15 items is " << subtotal 
         << ", and the tax for " << subTotal << " is " << tax << endl;
    //end of fragment

    void calculateCost(int count, float& subTotal, float& taxCost){
         if ( count < 10){
            subTotal = count * 0.50;
         } else {
            subTotal = count * 0.20;
         }
         taxCost = 0.1 * subTotal;
    }

9. What is wrong with the following function body?
   void calculate(int count, float price, float& cost)
   {
       if (count < 0)   
           cost=0.0;
        else
            cost=count*price;
        return;
    }

10. "#include <cmath>" is known as an ___________________.

11. When overloading a function, what must be true?
   a. The names should be different with the same number and/or types of
      parameters.
   b. The names should be the same with different number and/or types
      of parameters. 
   c. The names should be different with different number and/or types
      of parameters. 
   d. The names should be the same with the same number and/or types
      of parameters.

12. What is the opposite of ( x < 20 && x > 12)? _______________________

13. In a compound logical and (&&) expression, the evaluation of the
    expression stops once one of the terms of the expression is
    false. This is known as ___________________.

14. Write a function which returns the max of a vector of integers.

15. Write a function which returns the min of a vector of integers.

16. Write a function which returns the min, max, and standard
    deviation of a vector of values.  Assume you have functions min,
    max, and stdev already defined for vectors.

17. A digit that can hold a zero or a one is known as a ___________.

18. If your program compiles and runs, but gives an incorrect output,
    this is known as a _________ error. 

19. Who developed C++?
    a.  Bjarne Stroustrup
    b.  Ken Thompson
    c.  Charles Babbage
    d.  Ada Lovelace

20. What does the following print to the screen?
