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)
C Sharp Random Number File writer and Reader
Create an application that writes a series of random numbers to a file. Each random number should be in the range of 1 through 100. The application should let the user specify how many randome numbers the file will hold and should use a SaveFileDialog control to let the user specify the file's name and Location.
Create another application that uses an OpenFileDialog control to let the user select the file that was created above. This application should read the numbers from the file, display the numbers in a ListBox control and display: the total of the numbers and the number of random numbers read from the file.
Line Numbers
Write a program that asks the user for the name of a file. The program should display the
contents of the file with each line preceded with a line number followed by a colon. The
line numbering should start at 1.

- Files Class Activity Write a program to write your first name (hard coded) to the screen and possibly to a file whose name is passed into the program from the command line. It can be written in upper or lower case or mixed case as the default. Usage: writer [-f filename] If the -f option is included with a filename, then create a file with that name or overwrite a previously existing file and write your name in on the first line. If the -f option is not included, then only write your name to the screen followed by a newline. Use a copy of the original getopt to parse the command line.
