The strlen() method is used to find the length of the string and it is defined in the string.h header file. Keep in mind that the number may be positive or negative, so we can go off the alphabet in both directions. Get code examples like "write a program to implement caesar cipher in java" instantly right from your google search results with the Grepper Chrome Extension. The result of the process is then taken under modulo division, essentially meaning that if a letter is shifted past the end of the alphabet, it wraps around to the beginning i.e we again start from a.
