1 It is most beneficial to you to write this mock midterm UNDER EXAM CONDITIONS. This means: Complete the midterm in 1.5 hour(s). Work on your own. Keep your notes and textbook closed. Attempt every question. After the time limit, go back over your work with a different colour or on a separate piece of paper and try to do the questions you are unsure of. Record your ideas in the margins to remind yourself of what you were thinking when you take it up at PASS. The purpose of this mock exam is to give you practice answering questions in a timed setting and to help you to gauge which aspects of the course content you know well and which are in need of further development and review. Use this mock exam as a learning tool in preparing for the actual exam. Please note: Come to the PASS workshop with your mock exam complete. During the workshop you can work with other students to review your work. Often, there is not enough time to review the entire exam in the PASS workshop. Decide which questions you most want to review the Facilitator may ask students to vote on which questions they want to discuss in detail. Facilitators do not bring copies of the mock exam to the session. Please print out and complete the exam before you attend. Facilitators do not produce or distribute an answer key for mock exams. Facilitators help students to work together to compare and assess the answers they have. If you are not able to attend the PASS workshop, you can work alone or with others in the class. Good Luck writing the Mock Exam!! Dates and locations of mock exam take-up: Tuesday, October 10 th 6:00-8:00pm in ME 3275 Wednesday, October 11 th 6:00-8:00pm in ME 3380

2 Technical Instructions: 1. All code required for this test is to be written in C--/C++ a. Pseudo code is not acceptable, e.g. you cannot use words like and and or. b. You must include brackets and semi-colons as per valid C++ syntax. c. You may only use the C--/C++ statements listed in the reference. Note that the only variable type permitted is double (no int variables allowed). d. You do not need to write any of the C++ code from framework.cpp, e.g. #include s, int main(), return 0, etc. 2. Your answers to the programming questions must include: a. variable declarations b. comments c. proper indentation

3 QUESTION 1 (10 marks) Select the best answer from the following 1. The value of pi ( ) would most likely be represented as: a. Variable b. Constant c. Double d. Integer 2. Using De Morgan s Law, ((a > b) && (a!= c)) could be rewritten as: a. (a > b) (a!= c) b.!((a>b) && (a!=c)) c.!((a<=b) (a == c)) d. None of the above 3. In C--the result of 6+2*4/3 would be: a b c d What would? need to be to make the following statement true (?<4) && ((8>4) &&(?>1))? a. 10 b. -2 c. 2 d. It will never be true

4 5. How many times would the following program output an x? double usernum = 10; while (usernum>1) { } a. 5 b. 4 c. 6 d For computer architecture, the term storage is used to describe: a. The computers ability to hold and process large amounts of information b. The input c. The Random-Access Memory (RAM) d. How quickly the CPU can access information 7. When a software application is deployed on a computer that emulates another computer it is referred to as: a. Operating system b. Virtualization c. Cloud cout << x ; usernum = usernum 2; d. Output device

5 8. In C--/C++ what is equivalent to (x!= y && y!= z)? a.!(x == y && y == z) b.!(x == y y == z) c. (x!= y y!= z) d. None of the above 9. What would be the result of pow(2,3)? a. 8 b. 9 c. 6 d Which statement below will always execute at least once? a. If b. Do while c. Else d. While

6 QUESTION What is the output of the following code (3 marks): double x = 1; double y = 5; while (y >= x) { if (x >= 0) { y = y - x; } else { x = x + 2; } //endif }//endwhile cout << x << << y; a. 1 0 b. 1 1 c. 3 5 d. 11 0

7 12. What is wrong with the following code? The code should output the number of asterisks corresponding to the value stored in x. (2 marks) Ex. If x = 4 the output would be **** double x = 4; double n = 0; while (n < 4) { cout << * ; n=n+1; }//endwhile a. The condition should be (n <= 4) b. Should have an endl at the end of the cout statement c. Should use an if statement not a while loop d. Nothing is logically wrong

8 QUESTION 3 (10 marks) Convert the following flowchart to C--/C++ code, make sure you declare any variables that you need. Start r = 6 t = 0 No t <= r Yes Add 1 to t, store in t r > 10 Yes Subtract 2 from t and store in t No r == t Yes Add t to r and store in r No End

10 QUESTION 4 (10 marks) Create C--/C++ statements that would execute the following instructions, no variable declarations are required. Your age can generally be used to classify you as a baby, toddler, kid, teenager or adult. If you are 1 years old or less, you are considered a baby. If you are older than 1 but less than 5 (inclusive) you are a toddler. If you are older than 5 but less than 13 (inclusive) you are a kid. If you are older than 13 but less than 17 (inclusive) you are a teenager. If you are 18 or older you are considered an adult. Assume the age of a user is stored in the variable userage. Create a single if statement that outputs what the classification (words in quotations above) is for userage and an endl. Only one message should be output.

11 QUESTION 5 (15 marks) Create a C--/C++ program that will: Get an input number from a user and tests to see if the value entered is an integer between -100 and If it is not, prompt the user until a valid number is input. If the number entered is a positive number, the program should output the corresponding negative value If the number is negative, the program should output the squared value (x 2 ) of the input If the number entered is zero, the program should output an exclamation mark (!) Remember to declare all variables Should make use of a sentinel loop to take multiple input values from the user
