C++ language Suppose a file contains the final grades of a class. Assume that the number of student gradesstored in a file is not known, but does not exceed 150. Write a complete C++ program toperform the following computations.1. Write a function to load the grades from a text file into an array, and returns the totalnumber of grades:int readData(ifstream fileID, int list[])2. Write another function to find the average of all grades and returns the average:double getAverage(const int list[], int length)3. Write another function that returns the number of students whose grades are above theaverage:double aboveAverage (const int list[], int length, doubleavg)where,fileIDis the identifier for the input file;list[] is an integer array with size 150 for storing data;length is the actual size of the stored data.avg is the averageIn the main () function, you should1) open the input text file with filename "gardes.txt"2) call readData() function to load the data into an array3) call getAverage() function to compute the average4) call aboveAverage() function to find the number of grades above the average.5) close the input file.

In the main () function, you should 1) open the input text file with filename "gardes.txt" 2) call read Data() function to load the data into an array 3) call getAverage() function to compute the average 4) call aboveAverage() function to find the number of grades above the average. 5) close the input file.
