Three cars drive a 500-mile route. Write a program that inputs the car's make and the number of gallons of fuel used by each car. After calling a "calcMPG()" function once for each car, have main determine and display which car was the most fuel-efficient and how many miles per gallon it got. The "calcMPG()" function should be passed the distance driven and the gallons of gas used as arguments, and should return the miles per gallon obtained.

4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }
Problem: A small company needs an interactive program to compute an employee’s paycheck. The payroll clerk will initially input the data, and given the input data, an employee's wage for the week should be displayed on the screen for the payroll check. The data for the employee includes the employee's hourly pay rate and the number of hours worked that week. Wage is equal to the employee's pay rate times the number of hours worked (up to 40 hours). If the employee worked more than 40 hours, wage is equal to the employee's pay rate times 40 hours plus 1½ times the employee's pay rate times the number of hours worked above 40. Instructions: Match the action at the left-side with the correct step number at the right-side (the attached picture). Note that it may be possible to group more than one related actions in the same logical step / process without altering the essence of the algorithm. In the program flow, input and checking of hourly pay rate should come before that of the number…
In Python Text-based adventure game: Pretend you are creating a text-based adventure game. At different points in the game, you want the user to select to fight, run, or hide from certain enemies. The selection variable must be sent as an argument into the choice() function. The user should enter 1 to fight, 2 to run, or 3 to hide in the main(). The choice() function should print one of the three options. Add an if statement in the choice() function to make the correct selection.
QUESTION 2 An event for a company is designed to bring customers from Kuala Lumpur to a gathering in Kota Bharu, Kelantan. The distance between Kuala Lumpur and Kota Bharu is 450 km. The cost of traveling depends on the type of car chosen by the customer, as shown in Table 1. Write a program that requests the car preference of the customers. Then the program calculates the cost of travelling based on the following formula: Cost = Price per liter/KM per liter × Distance travel The current prices per liter are RM2.05 and RM1.50 for gasoline and diesel, respectively. The liter per KM for each car is provided in Table 1. Table 1 Car Fuel type KM per liter Мyvi Gasoline 25 Perdana Gasoline 19 Triton Diesel 10 Ranger Diesel 15 Ria Gasoline 16 Sample output: Please enter your car type: Triton You choose Triton that uses diesel fuel. The cost is RM120. Please pay RM120 to the front office. Thank you.
Java Language The company will held its quarterly performance for each department; wherein each group of the department are rated from 1 to 5, where 1 is the lowest score and 5 is the highest score. The department has two groups, groupA and groupB. Each group will be rated by five evaluators. Create a program that will ask for the input rate of the evaluators, and determine the group that got the highest rating, as well as the overall rating of the department. Use the UML diagram below as a reference. Department() – accepts 5 ratings of the evaluators and determines the groupScore which is the total rating of the group. getGroupAverage() – returns the value of groupAverage which is the average score of the group. displayAverage() – displays the overAllAverage which is the average of the whole department. overAllScore is the over all score of the department. Department Group Score: Int Group Average : Double Overall Score: int overall Average: double Department()…
Bob a builder has come to you to build a program for his construction business. He needs to determine the square footage of a room in order to buy material and calculate costs.Bob charges $425 per square metre.the program is going to ask the user to enter the name of a room . It will then ask you for the width and length of a room (in metres) to be built.the program will calculate the room area and use this information to generate an approximate cost. Your program will display the room , the total area and the approximate cost to the screen
The cost to become a member of a fitness center is as follows: (a) the senior citizens discount is 30%; (b) if the membership is bought and paid for 12 or more months, the discount is 15%; and (c) if more than five personal training sessions are bought and paid for, the discount on each session is 20%. Write a menu-driven program that determines the cost of a new membership. Your program must contain a function that displays the general information about the fitness center and its charges, a function to get all of the necessary information to determine the membership cost, and a function to determine the membership cost.
Snowball fight Write a programto calculate the volume of snow needed for a snowball fight. Use separate functions to: Print directions / an intro message to the user. Read the number of snowballs from the user. Calculate the volume of a snow required for the snowballs, in cubic feet. Use a constant of 4 inches for the diameter. Print the snowball size, number of snowballs and volume of snow needed. Use 1 decimal place for the snowball size and snow volume. Youroutput should be nicely formatted, with units. Complete the CSC 150 Design Document for your program. Draw a Structure Chart in the space at the top of the document. Below, give the prototype and a brief description for each function. The space in between is for the variables that you're defining in 'main'. It's helpful to list these before you write your function prototypes.

Problem Description: The bird of paradise called the Helipixsal is renowned for its magnificent tail feathers which range in number from five to nine ornate feathers each of a different length. Their "magnificence" is quantified by the rather simple process of counting the exact number of tail feathers and multiplying this by the difference in the length of the minimum and maximum lengths of tail feather. You are to write a simple program that will allow the user to enter the length of each tail feather individually and keep on entering feathers until a -1 is entered. The program will then return the quantified "magnificence" factor.
This function determines the winner of the match based on the score totals for all the rounds. The input to this function is the computer's final score and the player's final score. This function examines the scores and displays the winner as follows: •Player score is higher than computer score, message is "Player wins!" •Computer score is higher than player score, message is "Computer wins!"• Player score the same as computer score, message is "No winner, it's a draw!" The function takes two integer parameters, evaluates them and outputs an appropriate message. This is a void function. PYTHON
Q6: The volume of oil stored in an underground 200-foot deep eylindrical tank is determined by measuring the distance from the top of the tank to the surface of the oil. Knowing this distance and the radius of the tank, the volume of oil in the tank can be determined by using this formula: volume = 7 radius (200- distance) Using this information, write a program that uses a function called volume to calculate the volume of oil in the tank.
