27. Create one text file store some information into it and print the same information on
Terminal.
28. A file named data contains series of integer no. Write a c program to read that no. and then
Write all odd no into file named odd no. and write all even no into file named even no.
Display all the contents of these file on screen.
29. Write a c program to read data from keyboard, write it to a file called input and Display data
of input file on the screen.
