(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.
Instructions Write a program in C++ that uses a two-dimensional array to store the highest and lowest temperatures for each month of the year. The program should output the average high, average low, and the highest and lowest temperatures for the year. Your program must consist of the following functions: Function getData: This function reads and stores data in the two-dimensional array. Function averageHigh: This function calculates and returns the average high temperature for the year. Function averageLow: This function calculates and returns the average low temperature for the year. Function indexHighTemp: This function returns the index of the highest high temperature in the array. Function indexLowTemp: This function returns the index of the lowest low temperature in the array. These functions must all have the appropriate parameters. An example of the program is shown below: Enter high temperature for each month 60 68 72 72 73 76 80 81 75 72 67 66 Enter low temperature for…
Programming Assignment Create a program application using C#, C++, or your preferred software for a small Employee Payroll system using one dimensional arrays. Include the following for at least 5 employees for a period of 3 months (assume the employees are paid monthly) a. hourly wages b. monthly earnings c. annual earnings d. monthly deductions (look the basic deductions) e. annual deductions f. net pay g. gross pay
Write a C++ program. The program should keep an array of nine structures. Each element is for a different player on the team. When the program runs it should ask the user to enter the data for each player. The program should also calculate and display the total number of runs scored by the team. The name and number of the player with the most runs should also be displayed. Input Validation: Do not accept negative numbers for player's numbers or points scored.
1.Write a c++ program that identifies the shortest and longest word stored in an array of maximum size 100. It should then display the words together with their respective lengths and location in the array. The program should also display the average word length in the array. If there are multiple shortest and longest word, the first ones are selected. 2.Write a C++program that records information of cars in an array. Each car details include its model, year registered and plate number. The program should allow the user to perform the following tasks : a) Add car details into the array. If the array is full, the program should notify the user. b) Remove any car details from the array by searching a specific car. c) List down number of cars registered each year, provide that the registered year existed in the array.

Create a c++ program that makes use of three arrays ; name, mark , grade. The programme should accept the names and marks of students to be entered by the user. Use the number of students as the size of the arrays. Grades are computered and stored in the grade array using the critirial: 100- 60=A; 59 - 40 = B below 40 = C The programme should continuously request a user who enters a mark below 0 or above hundred to enter a mark in the range of 0 - 100. Finally the programs should display the list of students in the this format : Name | Mark| Grade
In c++ Write a program which asks user to enter total number of customers who have bought fruits today, create an array dynamically, then asks user to enter quantity of fruit bought and price per kg of item ( e.g. for one kg apple= 200rs.) calculate the bill and stores the bill in the array. At the end you have to display the total earning of the shop in a day.
using c++ write a program You have to write a C++ program to input and store the data of 500 candidates who have applied at BIIT to get admission in BS program starting from spring 2021 semester. Program should store Name, phone no, address, and FSc Marks of every candidate (you should use array of structure to store this information). After getting input, sort the array on the basis of FSc marks in descending order. Then print the merit list i.e. print names of all the candidates (sorted on the basis of FSc Marks in descending order).

Exercise 2 This exercise is designed to assess student’s skills of writing programs using arrays and loops. Write a C++ program using array and loop that prompts a user to enter 15 Students’ marks in ProgramDesign and Implementation (PDI) Module in an array. The program sorts the students’ marks in descending order using a loop and displays the marks of all students as well as lowest, highest, average marks, and the class result based on the average module marks. The result criteria is given below:Average is less than 40 = Poor ResultAverage is between 40 to 49 = Fair ResultAverage is less than 50 to 59= Good ResultAverage is less than 60 to 69 = Very Good ResultAverage is between 70 to 79 = Excellent ResultAverage is 80 or greater = Outstanding ResultNote: You must demonstrate the use of arrays and loops. Your code must be properly commented Sample Output:Welcome to Result Management SystemEnter PDI Marks of Student 1: 50Enter PDI Marks of Student 2: 35Enter PDI Marks of Student 3:…
1. Write a program (C++) and algorithm that will calculate the average of test scores. It will ask the user for number of students and the number of test scores per student. 2. Create a program (C++) and algorithm that uses an array to store the results from a poll of 25 people. Each person was asked to estimate the amount of time, in minutes, that he or she spends on Facebook each day. The program should allow the user to enter a specific number of minutes and then display the number of people spending more than that length of time.
