CSC 1300 Exam 4 Comprehensive-ish and Structs December 8, 2017 Name: Read through the entire test first BEFORE starting Multiple Choice and T/F sections should be completed on the scantron Test has two sections worth a total of 100 points o True / False / Multiple Choice 30 questions, 75 points o Code 1 question, 25 points Section 1 (75 points) 1. This is required after the closing brace of the structure definition a. Curly bracket b. Square bracket c. Period d. Semicolon 2. Look at the following statement booklist[2].publisher[3] = t ; This statement a. Is illegal in C++ b. Will change the publisher s name of the second book in booklist to t c. Will store the character t in the fourth element of the publisher member of booklist[2] d. Will ultimately result in a runtime error 3. You may use a pointer to a structure as a a. Function parameter b. Structure member c. Function return type d. All of these 4. Data types that are created by the programmer are known as a. Variables b. Abstract data types (ADT) c. Functions d. Parameters 5. Before a structure can be used, it must be a. declared b. dereferenced c. initialized d. constructed Pg. 1
6. The, also known as the address operator, returns the memory address of a variable a. asterisk b. ampersand c. percent sign d. exclamation point 7. When you work with a dereferenced pointer, you are actually working with a. a variable whose memory has been allocated b. a copy of the value pointed to by the pointer variable c. the actual value of the variable whose address is stored in the pointer variable d. all of the above 8. A function return a structure a. will always b. may c. may not d. cannot possibly 9. To dereference a structure pointer, the appropriate operator is a. the ampersand, & b. an asterisk, * c. the structure pointer operator, -> d. the dereference operator, <- 10. If Circle is a structure, the statement Circle* pcirc = nullptr; a. is illegal in C++ b. initializes a null pointer with the value of the Circle pointer c. declares an empty structure variable called *pcirc d. declares a structure pointer called pcirc initialized with a null pointer 11. With an enumerated data type, the enumerators are stored in memory as a. strings b. integers c. characters d. doubles 12. A struct can contain members with varying data types 13. If a function is legally prototyped to return an integer value, it can return a structure member that is an integer data type 14. Dynamic memory allocation occurs when a. a new variable is created by the compiler b. a pointer fails to dereference the right variable c. a new variable is created at runtime d. a pointer is assigned an incorrect address Pg. 2
15. Every byte in the computer s memory is assigned a unique a. pointer b. address c. name d. dynamic allocator 16. C++ does not perform array bounds checking, making it possible for you to assign a pointer the address of an element out of the boundaries of an array 17. The ampersand is used to dereference a pointer variable in C++ 18. Relational operators allow you to numbers a. add b. multiply c. compare d. average 19. Assuming the user enters a 90 to the keyboard, what will the following code output? cout << Enter a test score ; cin >> testscore; if (testscore < 60); cout << You failed the test << endl; if (testscore > 60) cout << You passed the test << endl; else cout << You need to study for the next test! << endl; a. You failed the test b. You passed the test c. You failed the test You need to study for the next test! d. You failed the test You passed the test 20. This operator represents the logical AND a. ++ b. c. && d.! 21. Input values from the user should always be checked for a. Appropriate range b. Reasonableness c. Division by zero (if division taking place) d. All of these Pg. 3
22. The default section is required in a switch statement 23. As a rule of style, when writing an if statement you should indent the conditionally executed statements 24. To access an array element, use the array name and the element s a. Data type b. subscript c. numbers d. constants 25. The name of an array stores the of the first array element a. memory address b. data type c. element number d. value 26. Which of the following is a valid C++ array definition? a. int scores[0]; b. float $payments[10]; c. int readings [4.5]; d. int scores [10]; e. B and D are both valid 27. An array with no elements is a. legal in C++ b. illegal in C++ c. automatically furnished with one element with a value of zero d. automatically furnished with one element, the null terminator 28. A for loop contains three expressions, initialization, test and a. update b. reversal c. null d. validation 29. One reason for using functions is to break programs into manageable units, or modules 30. All of the other True/False questions were True Pg. 4
Section 2 Code (25 points) You have been hired by the National Collegiate Athletics Association (NCAA) to help build a database of all of their 300+ member schools. Your job will be to create the initial data type to hold the information the association keeps on each school. This information is : A string containing the name of the institution (e.g. Tennessee Tech University) A string containing the institutions team name (e.g. Golden Eagles) A string containing the city where the institution is located (e.g. Cookeville) A string containing the state where the institution is located (e.g. TN) An integer containing the year the when the institution was founded (e.g. 1917) An integer containing the total wins all time for the institution An integer containing the total losses all time for the institution A Boolean indicating if the school is currently on probation A string indicating the conference the school currently plays in A string indicating which division the school currently plays in Remember, you are only responsible for creating, displaying and deleting a single team. You must create the.h prototype file as well as the.cpp file containing your code. Pg. 5
