Please give me a step by step solution for this question, using only the regular c-instructions offered with hack assembly language.
The ROT-13 algorithm encrypts a string one character at a time by adding 13 to the value of the internal representation of the character. We want our encryption scheme to cover the entire printable ASCII range. After examining the ASCII character set and their internal representations, we see that characters 0 through 32 and character 127 are control characters. Technically, characters 32 (space) and 127 (DEL) are printable, but we don’t want to include them in our encryption routine. Therefore, we want our encrypted string to only contain characters in the range of 33 through 126. As an example: Plaintext: Norwich Ciphertext: [|!&vpu The internal representation of ‘N’ is 78. 78 plus 13 is 91, which is the character ‘[‘. The internal representation of ‘o’ is 111. 111 plus 13 is 124, which is the character ‘|’. The internal representation of ‘r’ is 114. 114 plus 13 is 127. Since 126 is our maximum value for our desired printable range, we…
