Grade Book A teacher would like to assign a letter grade to a student, based on student's test score. Write a program to help this teacher managing her students' test score. Use the following grading scale to assign a letter grade to a student. Test Score Letter Grade 80 - 100 A 70 - 79 B 60 69 C 50 - 59 0- 49 F Your program must have an array of string objects to hold the student names and an array of int to hold the student scores. Let the teacher determines the number of students and ask the teacher to enter the information for each student. Your program should have the following programmer-defined functions: getInput () - to read the students name and scores from user getGrade () - to determine the letter grade corresponding to the score getReport () - to determine the maximum, minimum, average and standard deviation of the scores Display an error message if the teacher enter mark below 0 or above 100, and keep asking for a valid value. The program should also be capable of…
Ch7 - Arrays java In a loop, ask the user to enter 10 integer values and store the values in an array. Pass the array to a method. In the method, use a loop to subtract 5 from each element and return the changed array to the main method.In the main method, use a loop to add the array values and display the result.
Flowchart for student interface program please. Create a program to enter grades and calculate averages and letter grades. Need a class which will contain: Student Name Student Id Student Grades (an array of 3 grades) A constructor that clears the student data (use -1 for unset grades) Get functions for items a, b, and c, average, and letter grade Set functions for items a, n, and c Note that the get and set functions for Student grades need an argument for the grade index. Need another class which will contain: An Array of Students (1 above) A count of number of students in use You need to create a menu interface that allows you to: Add new students Enter test grades Display all the students with their names, ids, test grades, average, and letter grade Exit the program Add comments and use proper indentation. Nice Features: I would like that system to accept a student with no grades, then later add one or more grades, and when all grades are entered, calculate the final…
Assignment #1 Instructions: Assigning Seats - planeseats Through this programming assignment, the students will learn to do the following: 1. Know how to use a Makefile. 2. Perform basic C commands. 3. Use arrays, integers and strings. This assignment asks the user to write a program to assign seats in an airplane. There will be 12 seats on the plane, 4 in first class and 8 in economy. • The program should display the following menu for the user: Please type 1 for "first class" Please type 2 for "economy" Please type 0 to quit • If the user types 1 then the user should be assigned a seat in first class. If the user types 2 then the user should be assigned a seat in economy. • If the user types O for a sentinel value the program should ext with a O return code. • The program should then print a line indicating the seat the person was assigned. This would be like a boarding pass. • The program should not assign a seat that has already been assigned. If all seats in the desired section…
Computer Science C# Programming Object Orientation Please use Arrays or ArrayLists where appropriate Implement a menu driven program that has some operations for a food truck. A food truck has multiple food items as well as a menu which contains a selection of the food items which will be sold for that day. A maximum of 10 food items can appear on the menu for any day. For each food item keep a code, description, category, price and quantity in stock (code, description and category are not usually changed). Create a comma delimited text file called "items.txt" for 15 or more food items, indicating the item's description, category, price and quantity in stock. Read all the food items from the text file “Items.txt” Display all the food items available for this food truck. Continuously prompt the user for a food item’s code to be placed on the menu until the menu is full or the user enters -1. Note that only food items which have a positive quantity in stock may be added to…
Searching - a user should be able to search by ID or by item name create only one menu item for searching a user should be able to enter the name of the item using any case, (for example, sTRolleR) you may wish to store items in all lower/upper case to expedite the search write one search function that can search by ID and name and goes through the array of structs/objects only once show the entire record if found or an appropriate message if not Sorting - sort by any field write one function to sort by any field using a parallel array of pointers use Bubble Sort is not the most effective but the easiest to modify. do not copy and paste sort code five times into the same function. sorting using pointers is faster because you have to swap pointers only, which are normally stored in 4 bytes each; it also allows you to preserve the original order of the items If you choose to have a submenu, a submenu must have an option to go back to the previous menu or main menu if a user got…

2. Lottery Number Generator Design a program that generates a 7-digit lottery number. The program should have an Integer array with 7 elements. Write a loop that steps through the array, ran- domly generating a number in the range of 0 through 9 for each element. (Use the random function that was discussed in Chapter 6.) Then write another loop that displays the contents of the array.
