Create a BYTE array with the label ‘input’. This array may be of any length between 2 and 100. In the case of encryption ‘input’ will hold the plaintext and in the case of decryption ‘input’ will hold cypher-text. Create a BYTE array with the label ‘key’. This array will have length between 1 and (LENGHTOF input -1). Meaning the lower bound for ‘key’ is one character and the upper bound is one less than the number of characters in ‘input’. Create a BYTE variable named "options". This variable will be used to determine which procedures should be executed. If ‘options’ contain the value 1 it means the program should execute encryption procedure. If ‘options’ contain the value 0 (or any other value than 1) the program should execute decryption procedure.
