Write a C/C++ program that asks the user for three integer marks. These are the student marks out of 25 for class tests. Subsequently the program must ask the user for a big test mark out of 50. Test all values for validity. If a value is invalid, a message must be displayed, and the user must be repeatedly given chance to correct the input. The final mark is calculated with 50% class tests and 50% big test mark. The program must display the final mark, as well as a symbol representing the mark (see Table 1.1). The program must repeat until the user enters "-1" for the first class test. After the user has entered "-1", the program must display a summary of the marks, i.e. the average final mark, highest final mark, and lowest final mark. The program also displays the number of students that pass (mark>=50), pass with distinction (mark>=75), and the number of students that fail (mark<50).

Write a program that reads student scores, gets the best score, andthen assigns grades based on the following scheme:Grade is A if score is ≥ best -5Grade is B if score is ≥best -10;Grade is C if score is ≥best -15;Grade is D if score is ≥best -20;Grade is F otherwise.The program prompts the user to enter the total number of students, and thenprompts the user to enter all of the scores, and concludes by displaying the grades.Here is a sample run: Enter the number of students: 4 ↵EnterEnter 4 scores: 40 55 70 58 ↵EnterStudent 0 score is 40 and grade is FStudent 1 score is 55 and grade is CStudent 2 score is 70 and grade is AStudent 3 score is 58 and grade is C
Write a c++ program to assign passengers seats in an airplane. Assume a small airplane with seat numbering as follows: 1 A B C D 2 A B C D 3 A B C D 4 A B C D 5 A B C D 6 A B C D 7 A B C D The program should display the seat pattern, with an 'X' marking the seats already assigned. For example, after seats 1A, 2B, and 4C are taken, the display should look like this: 1 X B C D 2 A X C D 3 A B C D 4 A B X D 5 A B C D 6 A B C D 7 A B C D After displaying the seats available, the program prompts for the seat desired, the user types in a seat, and then the display of available seats is updated. This continues until all seats are filled or until the user signals that the program should end. If the user types in a seat that is already assigned, the program should say that that seat is occupied and ask…
In C++ , Write a program for a Bookstore to take an order from a customer, calculate how much to charge a customer based on his/her order, and display a receipt. The store sells only three books, designated by their authors: Cervantes ($41.25 each), Homer ($15.85 each), and Shakespeare ($30.50 each). Your program is to work as follows: Display a welcome message (e.g., “Welcome to the Bookstore!”) Prompt the user for his/her first name Prompt the user to input the number of books by Cervantes s/he wants Prompt the user to input the number of books by Homer s/he wants Prompt the user to input the number of books by Shakespeare s/he wants Compute the total amount due, including a 10% sales tax Display amount due Ask the user how much money s/he will pay Display a receipt listing the name of the user, the quantity of each item ordered, the total cost of the order, and the amount the user will have left after paying Execution of the compiled program should appear roughly as follows…
In python, a) In the Hi-Lo game, the player begins with a score of 1000. The player is prompted for the number of points to risk and a second prompt asks the player to choose either High or Low. The player’s choice of either High or Low is compared to a random number between 1 and 13, inclusive. If the number is between 1 and 6 inclusive, then it is considered “low”. A number between 8 and 13 inclusive is “high”. The number 7 is neither high nor low, and the player loses the points at risk. If the player had guessed correctly, the points at risk are doubled and added to the total points. For a wrong choice, the player loses the points at risk. Create a HiLo application based on this specification. Application output should look similar to b) Modify the application to allow the player to continue until there are 0 points left. At the end of the game, display the number of guesses the user took before running out of points.
QUESTION 7. Write a program that reads multiple integers from the user and finds the largest value. The program should ignore negative values and print a message indicating so. The sentinel is -1. If no valid input is entered, the program should print a message indicating so, like the second sample below. Use a flag variable that indicates whether valid input has been entered so far or not. Enter integer: 4 Enter integer: -5 >>> Invalid input! Enter integer: 20 Enter integer: 12 Enter integer: 7 Enter integer: -1 The largest value is: 20 Enter integer: -5 >>> Invalid input! Enter integer: -20 >>> Invalid input! Enter integer: -1 No valid input was entered!
Write a program that reads student scores, gets the best score, and hence assigns grades based on the following scheme: Grade is A if score is > = best - 10; Grade is B if score is > = best - 20; Grade is C if score is > = best - 30; Grade is D if score is > = best - 40; Grade is F otherwise. The program prompts the user to enter the total number of students, then prompts the user to enter all of the scores, and concludes by displaying the grades. Language: C++

The Café Noir Coffee Shop wants some market research on its customers. When a customer places an order, a clerk asks for the customer’s zip code and age. The clerk enters that data as well as the number of items the customer orders. The program operates continuously until the clerk enters a 0 for zip code at the end of the day. When the clerk enters an invalid zip code (more than 5 digits) or an invalid age (defined as less than 10 or more than 110), the program reprompts the clerk continuously. When the clerk enters fewer than 1 or more than 12 items, the program reprompts the clerk two more times. If the clerk enters a high value on the third attempt, the program accepts the high value, but if the clerk enters a negative value onthe third attempt, an error message is displayed and the order is not counted. At the end of the program, display a count of the number of items ordered by customers from the same zip code as the coffee shop (54984), and a count from other zip codes. Also…
1. Write a pyrhon program that prints out a classic hangman stick figure. The program should ask the user to enter a number from 1-6 and the corresponding hangman should be printed. The value the user inputs corresponds to the number of incorrect guesses in a real hangman game and so the completeness of the hangman will correspond to the number of ‘incorrect guesses’ inputted by the user (e.g., if the user enters 1, then only the head of the hangman will be printed; full example below). Example:Enter a number from 1-6: 1O Enter a number from 1-6: 2O|Enter a number from 1-6: 3O\||Enter a number from 1-6: 4O\|/|Enter a number from 1-6: 5O\|/|/Enter a number from 1-6: 6O\|/|/ \ 2. Modify your program from problem 1 so that the user input is checked to be a validsingle digit (1-6) before printing the corresponding hangman. If the input is not valid, theninstead of a hangman the following message should be printed “Invalid input: you must enter asingle number from 1-6.” Example:Enter a…
In Python Write a program that computes the fuel efficiency for a multi-leg journey. The program will first prompt for the starting odometer reading and then get information about a series of legs. For each leg, the user enters the current odometer reading and the amount of gas used (separated by a space). The user signals the end of the trip with a blank line. The program should print the miles per gallon achieved on each leg and the total MPG for the trip
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, etc.)• Hospital medication charges.Use a single, separate 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 overloaded functions to calculate the total charges. One of the functions should accept arguments for the in-patient data, while the other function accepts arguments for out- patient data. Both functions should return the total charges.
The programming language is C++, write a program base on the given statement. 1. An employee’s weekly working hours is 40. If an employee exceeds40 hours, it is considered overtime. Create a program that will acceptthe number of hours worked by employee and his / her hourly rateand print the gross pay and overtime pay rendered, if there’s no OTpay to print, print only the gross pay. To compute for the gross pay of an employee, multiply the number of hours worked by his/herhourly rate plus his/her OT pay. OT hours are time rendered byemployee over 40 hours. The overtime hours rendered should becomputed by using 1.50% of his hourly rate.
