You will be writing only the function definition. Write the function definition for AddBonus . The function will take two arguments, a double array called grades and an integer called numGrades. numGrades is the count of how many grades are in the array This function will have a void return type. Inside the AddBonus function: • Declare a file pointer and a double variable and connect to a file called "input.txt" • read one double value from the file add the double value that was read from the file to all the grades in the array Assume the file has the correct name and data
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. I will provide you with a driver called hw1.cpp in ~cthorpe/public/142 and with a test file HW1.txt in the same…

Complete the following sentence. If more than one function is present in a file, the top function is a normal or function, while the ones below it are called local functions.
In C Programming Language. - use user-defined functions.- use an array of arrays.- use file pointers- use string processing and character conversions.- use a dynamic memory function calloc() or malloc() - Demonstrate the ability to read a file and process the data. Problem: You are tasked to write a program that will perform a statistical analysis of student records. Your program will open a text file (provided) and store the values read into an array (2d). Your program will then close the input file and process the data. Your program will print out the records to screen and will then print out the average quiz scores per student.For each student in the provided text input file there is a name of up to 20 characters, an id number of five alphanumeric values (n1234), 4 exm grades in order: exm 1 – exm 4.You may use a fixed 2d array size of 80 characters for the input file name. You must use a dynamic array for at least one task in your program. You may declare your filename array using…
DescriptionWrite a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: each line contains a student's first name, then one space, then the student's last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The date in the output file will be nearly the same as the data in the input file except that you will print the names as last-name, first-name; each quiz score, and there will be one additional number at the end of each line:the average of the student's ten quiz scores.Both files are parameters. You can access the name of the input file with argv[1]. and the name of the output file with argv[2].The output file must be formatted as described below: 1. First and last names…
Do not copy paste from any source else downvote Write a void function that will merge the contents of two text files containing chemical elements sorted by atomic number and will produce a sorted file of binary records. The function’s parameters will be three file pointers. Each text file line will contain an integer atomic number followed by the element name, chemical symbol, and atomic weight. Here are two sample lines: 11 Sodium Na 22.99 20 Calcium Ca 40.08 The function can assume that one file does not have two copies of the same element and that the binary output file should have this same property. Hint: When one of the input files is exhausted, do not forget to copy the remaining elements of the other input file to the result file.
8-15. Printing Models: Put the functions for the example printing_models.py in a separate file called printing_functions.py. Write an import statement at the top of printing_models.py, and modify the file to use the imported functions.
This part of the quiz will contain 4 parts. A function called grade, a function called pgrade, a prototype file called grade.h and a main function. In this part you will create the main function which will do the following: main This main function will use the functions grade and pgrade to produce the grades for the following students and display the appropriate grade with the appropriate message. The semester grade will be based on the fact that the quiz average is 25% of the grade, the final is 20% of the grade, assignments is 20% of the grade and programs are 35% of the grade. The student grades are as follows: Student Name Assignments Programs Quiz Ave Final Tom 63 Francis Maria Jan 75 90 95 85 sample of output Harry Grade B Good 85 75 95 90 93 92 71 69 87 91 73 A
1. Write a program named program61.py This program will have three functions, the main() create() and retrieve(). main() will call: create() and main() then calls retrieve() create() will prompt the user to enter any number of course name | grade values. The course name ,AND calculated class GPA ( not the class grade ) are the written one value per line to a file named grades.txt ( review example of grades.txt below! ). Pressing Enter with no input value on the course name will exit the loop, close the file, print "File was created and closed" and return the bool value True to the main(). See Simple GPA Tip below. retrieve() will open and read grades.txt. The function then will print the course names and Class GPA as shown below. The average of all class GPA values should be calculated and displayed to two decimal places and then return variable used for the GPA average to the main() . See sample run below in which 2 course names were entered, but note that more or fewer…
Requirements: You are to ask the user: 1) For the name of the input file (CTIM375-Input.dat; a downloadable file), 2) Read the file into an array, 3) Sort the array in ascending order using the name field, 4) Add a field at the end of the records that will contain the average of all the amount fields within the record, and 5) Produce a comma-separated value (.CSV) file called "CTIM375-Output.csv".
