Write a program that shows Game sales. The program should use a structure to store the following data about the Game sale:
Game company
Type of Game (Action, Adventure, Sports etc.)
Year of Sale
Sale Price
The program should use an array of at least 3 structures (3 variables of the same structure). It should let the user enter data into the array, change the contents of any element and display the data stored in the array. The program should have a menu driven interface.
Input Validation: When the data for a new game sale is entered, be sure the user enters data for all the fields. No negative amounts should be entered for a “Sale Price” of the Game
An example:
You will use 1 structure only and then manipulate that for working with the information.
The program should use an array of at least 3 structures (3 variables of the same structure).
An example of the structure:struct Game{string name;string type;int year;double price;};
So far I have written that ...
Class and Data members:
Create a class called Student that stores a student’s grades (integers) in a vector (do not use an array). The class should have data members that store a student’s name and course for which the grades are earned.
Constructor(s):
The class should have a 2-argument constructor that receives the student’s name and course as parameters and sets the appropriate data members to these values.
Member Functions:
The class should have functions as follows:
Member functions to set and get the student’s name and course variables.
A member function that adds a single grade to the vector. Only positive grades are allowed. Call this function AddGrade.
A member function to sort the vector in ascending order.
A member function to compute the average (x̄) of the grades in the vector. The formula for calculating an average is
x̄ = ∑xi / n where xi is the value of each grade and n is the total number of grades in the vector.
A member function to determine the lowest…
PROGRAMMING LANGUAGE: C++
Write a program which has a class named FileHandlerto read StudentName, MarksObtained from the attached picture. The class should have a function which calculates grade for a student and then adds it in a new column i.e. Grade. The grade should be calculated considering the following criteria.
A: 87-100, B+: 80-86, B: 72-79, C+: 66-71, C: 60-65, D: 50-59, F: 0-49

The point of the script is to read the pasted/attached Number_new.txt file's contents, meant to represent a classes' final grades out of 100 percent, and print an .exe screen as well as another .txt file that repeats the grade number with a letter grade and a PASS or FAIL next to it. At the end it needs to say how many students passed and how many failed. Nothing too complicated with the grading, just 90.0 and up is an A, 80.0 to 89.99 is a B, etc. And of course, anything below 60.0 is an F/FAIL. Please NO IOSTREAM.H OR CACIO.H!
