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.
