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; }
""" MovieGuide.py This program allows each theater patron to enter a value from 0 to 4 indicating the number of stars that the patron awards to the Guide's featured movie of the week.

15. Speed Conversion ChartYour friend Amanda, who lives in the United States, just bought an antique European sports car. The car’s speedometer works in kilometers per hour. The formulafor converting kilometers per hour to miles per hour is:MPH = KPH * 0.6214In the formula, MPH is the speed in miles per hour and KPH is the speed in kilometersper hour. Amanda is afraid she will get a speeding ticket, and has asked you to write aprogram that displays a list of speeds in kilometers per hour with their values convertedto miles per hour. The list should display the speeds from 60 kilometers per hourthrough 130 kilometers per hour, in increments of 5 kilometers per hour. (In otherwords, it should display 60 kph, 65 kph, 70 kph, and so forth, up through 130 kph.) made in visual studio 2017
Submit your answer in the comment section. Days of the Week Write a program that asks the user for a number in the range of 1 through 7. The program should display the corresponding day of the week, where 1- Monday. 2- Tuesday and so forth. If the user types in a 6 then "Saturday should be printed on the screen. For help with Input statements see: Input Function • The program should print an error message if the user enters a number that is outside the range of 1 through 7. For help with If statements and conditions see the following pages: If-Eke Statements and Operators • Name the source code file yourName HW4_1.py. • Test and run the program. Capture the output console and save it as an image file named yourName Hw3 output4 1jpg. • Submit the py and the image files through Canvas.

8. Total Purchase A customer in a store is purchasing five items. The prices of the five items are as follows: Price of item 1= $15.95 Price of item 2= $24.95 Price of item 3= $6.95 Price of item 4= $12.95 Price of item 5= $3.95 Write a program that holds the prices of the five items in five variables. Display each item's price, the subtotal of the sale, the amount of sales tax, and the total. Assume the sales tax is 7 percent.
A and BonlyIn this program, you are asked to write a program in assembly which works as a simple calculator.The program will get two integer numbers, and based on the requested operation, the result shouldbe shown to the user.a. The program should print a meaningful phrase for each input, and the result.i. “Enter the first number”ii. “Enter the second number”iii. “Enter the operation type”iv. “The result is”b. The user should enter 0, 1, and 2 to tell the program the types of operation add, sub, andmultiply, respectively.c. How many registers do you need to implement this program?d. What system calls do you need to write this program?
Language: Python Write a program that computes and displays the charges for a patient's hospital stay. First, the program should ask if the patient was admitted as an in-patient or an out-patient. If the patient was an in-patient the following data should be entered: - The number of days spent in the hospital - The daily rate -Charges for hospital services (lab tests, etc.) -Hospital medication charges If the patient was an out-patient the following data should be entered: -Charges for hospital services (lab tests, etx.) -Hospital medication charges Use a single, seperate function to validate that no input is less than zero. If it is, it should be re-entered before being returned. Once the required data has been input and validated, the program should use two seperate functions to calculate the total charges. One of the functions should accept arguments for the in-patient data, which the other function accepts arguments for out-patient data. Both functions should return the total…

Write algorithms to solve different programming problems using flowchart and pseudo-code. Problem: The program will display the following when run: 1. Display Pass/Fail Data 2. Display Final Grade Classification 3. Display Mean and Median Score Call the following function when the user selects from the menu: 1. Determine the number of students who passed (>=75%) and failed (<75%). Plot also the pass/fail data using a pie chart. 2. Classify and plot (using bar graph) the final grades based on the following: - Expert (95%-100%) - Competent (85%-94%) - Novice (75%-84%) - Beginner (<75%) 3. Calculate the mean and median final grade. Plot the mean and median score with the plot of all the final grades. Create an algorithm for the programming problem above using pseudo-code or flowchart.
