C PROGRAMMING HELP I need help fixing an old assignment of mine. 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! I cant use those header files. Below is the script: #include<stdio.h>#include<math.h>#define THEFILE "Number_new.txt" int main(){ float r0[10]; float rr[10]; FILE *fp; char line[81]; fp = fopen(THEFILE, "Number_new.txt"); if (fp != NULL) { /* The file is open. */ printf("%7s %7s %7s %7s %7s %7s %7s %7s %7s %7s\n", "0", "0.01",…

First programming homework Create a class of records for a gradebook called Rec. The data should be private, and should include a firstname, lastname, array of three grades, and a field for average grade. Build two constructors: a default constructor and a constructor that takes the first and last name. Build a function to read the data, either from a file or from cin. The read function reads the two names and three grades, but does not read the average grade. Build a write function that writes the data either to a file or to cout. The write function prints all of the data on one line with spaces between fields. Build a function to calculate the average grade field. Build an overloaded operator == to compare two records. This should be implemented as a friend function. Declare the constructors and functions in the body of the class, but implement them outside the class.

use c++ Programming language Write a program that creates a two dimensional array initialized with test data. Use any data type you wish . The program should have following functions: .getAverage: This function should accept a two dimensional array as its argument and return the average of each row (each student have their average) and each column (class test average) all the values in the array. .getRowTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The function should return the total of the values in the specified column. .getHighestInRow: This function should accept a two…
