CS50 Caesar – ASCII letters and Output format

by

First of all, you have to follow the specifications of the problem. That is, you have to print out the word ‘plaintext:’ before taking input and print out ‘ciphertext:’ before giving any output. As the checking process is automated, this becomes very important. Notice the case of those words in your problem statement.
Secondly, I will let you figure out the logic by yourself, which is the important part of the problem set. Try watching the next few lectures and learn how to use the debugger in the CS50 IDE. It will help you a lot to solve problems in your code on your own.
