Write C++ Program that does the following: •Instead of reading data from the user, I will give you a file, grades.txt (look in ~cthorpe/public/141) •The format of the file is: –First line: number of records –Subsequent lines:    Last name on a line by itself    First name and three homework grades   •Read function: parameters are –An instream, passed by reference, from which to read the data –Fields for firstname, lastname, grade1, grade2, grade 3 •The read function should read in the data from the instream. It is a void function •What types are the parameters? How will you pass them?   •Write function: parameters are –Firstname, lastname, grade1, grade2, grade3, average grade, letter grade –What types are those parameters? Do you need to pass them by reference? •The write function will write the data to the screen formatted neatly –Which formatting instructions will you need to use?   Overall program flow: •Open the file in the main program. •Read in the number of records •For each record, –Call the read function –Calculate the average score and letter grade –Call the write function –Update the running total of the average grades •At the end, close the file and output the overall average score.

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…

In Python  Write a program that consists of (at least) two function: A function that creates and saves data in a file. The saved data represents exam grades. In the function, you will create n random numbers in the range [0,100], where n is the number of students. The function can be called as follows: createFile(filename, n) Main function, in which the user inputs the file name and the number of students, then the main calls function createFile. The main should perform validation for n (should be > 0), and the filename (should end with .txt). I will explain how to validate strings in the coming lecture. Hint: a good developer will write four functions to solve the problem.

In java create a function searchstd() that reads a search record  from a text file file.txt when the function is called in main

This is phython not Java Lab:  Write a file copying program.  The program asks for the name of the file to copy from (source file) and the name of the file to copy to (destination file).  The program opens the source file for reading and the destination file for writing.  As the program reads each line from the source file and it writes the line to the destination file.  When every line from the source file has been written to the destination file, it close both files and print “Copy is successful.” In the sample run, “add.py” is the source file and “add-copy.py” is the destination file.  Note that both “add-copy.py” is identical to “add.py” because “add-copy.py” is a copy of “add.py”. Sample run: Enter file to copy from: add.py Enter file to copy to  : add-copy.py Copy is successful.   Source file: add.py print("This program adds two numbers")   a = int(input("Enter first number: ")) b = int(input("Enter second number: "))   print(f"{a} + {b} = {a+b}")   Destination…

9b_act2. Please help me answer this in python programming.

Write a C++ program that asks the user for a file name and a word for which to search.  The program should search the file for every occurrence of the word.  When the word is found, the line it contains should be displayed.  After all of the occurrences have been found, the program should display the number of times the word was found in the file.
