I hope it will run successfully because i didnt run it only wrote it... Check it for your self now...
Hope it will help...
Create three files namely all_numbers, odd_number and even_number.
Get the number of records and the numbers to store from the user.
Save all the numbers in “all_numbers” file. Read each number and check whether it is odd or even.
Store the odd numbers in odd_number file and even numbers in even_number file.
Finally, print the numbers stored in odd_number and even_number files.
