Exam2 Questions

In addition to the instructions on the screenshot, please ensure that your program is made in C++ with comments. Please also ensure that screenshots are taken for the source code and the executed version, including all possible cases. Finally, add your code in a manner so I can just copy and paste it for review. Thanks.

Program execution jumps to the function definition and executes the code in the function body. C. The function is destroyed. D. Program execution returns to where the function was called.   What is the best way to reuse lines of code? A. Copy and paste them wherever needed B. Lines of code cannot be reused C. Include them once at the top of the program D.

USE PYTHON Source: en.wikipedia.org/wiki/Camel_case In some languages, it’s common to use camel caseLinks to an external site. (otherwise known as “mixed case”) for variables’ names when those names comprise multiple words, whereby the first letter of the first word is lowercase but the first letter of each subsequent word is uppercase. For instance, whereas a variable for a user’s name might be called name, a variable for a user’s first name might be called firstName, and a variable for a user’s preferred first name (e.g., nickname) might be called preferredFirstName. Python, by contrast, recommendsLinks to an external site. snake caseLinks to an external site., whereby words are instead separated by underscores (_), with all letters in lowercase. For instance, those same variables would be called name, first_name, and preferred_first_name, respectively, in Python. In a file called camel.py, implement a program that prompts the user for the name of a variable in camel case and outputs…

Reviewing this program address the following points: Design/Implementation: Are there noticeable issues/flaws in the design and implementation of the code? How would you remedy such issues? Readability: Is the code well organized and easy to follow? Can you understand what is going on, easily? Documentation: Is the documentation well-written? does it explain what the code is accomplishing and how? Remember good documentation includes descriptive variable and function names in addition to clear/concise annotation. Efficiency: Was the code efficient, without sacrificing readability and understanding? #include <iostream> using namespace std; int main() {    double meal, tax, tip, total; //create variables    double taxPercentage = .0675, tipPercentage = .2; //initiate percentage values        cout << "Enter a meal charge: \n";    cin >> meal; //enter meal        tax = meal * taxPercentage;    tip = (meal + tax) * tipPercentage;    total = meal+tax+tip;         cout…

Which of the following statements about testing are always true. A. If a test fails, there must necessarily be a defect in the executed code. B. If a test passes, there cannot be a defect in any code executed by the test, but there could be a defect elsewhere in the function. C. If a test is unsound, that test passing or failing doesn't tell us whether or not a defect exists. D. All of the above are true

A function with parameters cannot be decorated. State whether true or false. a. False b. True

a c++ program for a (cafe system) that includes this specifications: -Functions (should include both: pass by value and pass by reference variables, void function and unction returning any value) - Array of structs (at least one single array of struct) - Selection and repetition structures as needed - Add your team members names as a comment in the first line of your program - You should print a menu to the user and offer him/her different services. - Main Services: 1-adding new item. 2-search for specific item. 3-update existing record. 4-delete. 5-Sort. 6-Display. 7-At the start, your program should populate the array(s) from a file and allow the user to edit it. At the end overwrite the same file with the latest contents of the array(s). 8-Provide another statistical report as separate text file e.g. the number of records, with date, time of last update. - The program should continue running until the user chooses to exit it. - Ensure to avoid any errors of any type (Run-time error,…

Write C++ program to currency exchange, which is the process that allows customers to exchange one currency for another. The program will include decision-making statements, loops, arrays, file I/O, string, and functions. You should be following below details: • As you might know, currency rates are influenced by several factors such a country's economic performance. Thus, it is better to get the up to-date currency rates from an external source as it is easier to update. You should read the data from the file "ExchangeRate.txt". • "ExchangeRate.txt" file contain: 1.00 SAR 0.08 KWD 1.00 SAR 0.97 QAR 1.00 SAR 0.98 AED 1.00 SAR 0.10 BHD 1.00 SAR 0.10 OMR 1.00 QAR 0.08 KWD 1.00 QAR 1.01 AED 1.00 QAR 0.10 BHD 1.00 QAR 0.11 OMR 1.00 KWD 12.00 AED 1.00 KWD 1.23 BHD 1.00 KWD 1.26 OMR 1.00 AED 0.10 BHD 1.00 AED 0.10 OMR 1.00 BHD 1.02 OMR The program should print the available currencies for exchange which are: o SAR --> Saudi Arabia Riyal o KWD --> Kuwaiti Dinar o QAR --> Qatar Riyal o AED -->…

Survey Data Analysis Computers are commonly used to compile and analyze the results of surveys and opinion polls. For this problem, there is a maximum of 30 responses for the survey. Each response is a number from 1 to 9. The program computes for the mean, median and mode of the 30 values. Mean - arithmetic average Median - middle value Mode - value that occurs most frequently The following are some of the function declarations that will be used by the program. Implement them. void initialize(int answer[], int size); initializes the array by inputting values float mean(int answer[],int size); computes for the average int max(int answer[],int size); returns the highest value int min(int answer[], int size); - returns the smallest value int range(int answer[],int size); returns the range of the highest and smallest values Provide the main that includes the creation of the array and tests of the operations.

True/False 7. Python functions can never modify a parameter

13.  What is the difference between a formal parameter and an argument? Group of answer choices A function’s argument is referred to as the formal argument to distinguish it from the value that is passed in during the function call. The parameter is the passed value. They are identical but using different terms. A function’s parameter is used for passing by reference. The argument is used for passing by value. A function’s parameter is referred to as the formal parameter to distinguish it from the value that is passed in during the function call. The argument is the passed value. A function’s parameter is used for passing by value. The argument is used for passing by reference.

Programming Language: C++ 3. Which of the following are true for static variables but not for other variables? Select one or more: a. If they are defined and initialized on the same line, this line is guaranteed to only be executed once. b. They can only be used in the scope where they are defined. c. They can be used as arguments when calling a function d. They retain the value stored in them even after the function where they are defined returns e. They can be defined and initialized on the same line.
