INTit

Create an array of 26 characters letters a-z

Create an getEncrypterdChar function.

This functions finds the index of a given character in the array and adds 13 to it.
It then checks if the index is greater than 26 and if so subtracts 26.
It then fetches the character at that index from the array.

In your main program read in the user input to be encrypted.
Loop over each character using a for loop passing the character to getEncrypted and printing out the result.

To decrypt encrypted text just do the same thing. This is a Caesar cypher called rot13
