File Handling Assignment -2 Write a program to generate a file numbers.txt that contains the first 50 odd natural numbers and each line in the file should contain 5 numbers only. Attach the screenshot of numbers.txt. In C or C++

python 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 1-100, 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 preform validation for n (should be > 0), and the filename(should end with .txt)

Two of the menu options (#2 and #3) are unfinished, and you need to complete the code necessary to write to and read from a binary file.  You will need to read through the code to find the functions that are called by these options, and then supply the missing code. Please help me get menu 2 and 3 to display properly.the .cpp and .h have the information:.cpp file:  // Corporate Sales Data Outputusing namespace std; #include <iostream>#include <fstream>#include <stdlib.h>#include "HeaderClassActivity1.h" int main() {    Sales qtrSales[NUM_QTRS];    while (true) {        cout << "Select an option: " << endl;        cout << "1.

File redirection allows you to redirect standard input (keyboard) and instead read from a file specified at the command prompt. It requires the use of the < operator (e.g. java MyProgram < input_file.txt) True or False
