Encrypt and Decrypt, Arrays/Pointers

[Dandirom]

Hi guys, I need help. I'd appreciate any pointers on how to go about with this problem. Thanks a lot.


Using arrays and/or pointers, make a prog that will ask for a string. 2 user-defined functions (encrypt() and decrypt()). encrypt the inputted string and display. e.g. HELLO->KHOOR......... ....orig: a-z,,,,code: d-z,a-c

Some tips:

- You may find the information at http://c-faq.com/ useful. Arrays and pointers are a confusing topic, so make sure you understand the difference between the two.
- If you can't figure out an algorithm in plain english, don't bother making it work in code. It needs to make sense in English first.
- Work piecemeal by piecemeal.
