C programming language Criteria graded:           Declare file pointers           Open file           Read from file           Write to file           Close file Instructions: Write a segment of code that opens a file called “numbers.txt” for reading.  This file is known to have 10 numbers in it.  Read in each number and print a ‘*’ to the screen if the number is even.  If the number is odd, do nothing.  Conclude by closing this file.

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 program

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. Be sure to test whether a file open succeeds or not and close any file you open when done.
