The matrix is 12x80. To read the file, read a line, store the 80 characters in a string and store the string in a Translation vector: vector translate. While the line-count is less than 13, read and translate the next line. Process the in-memory matrix and then read the next card. To Process the matrix, read the rows by the 80 columns. Each complete column is a EBDIC character. Lookup the EBDIC character in the tupleVector and find the ASCII character in the found tuple. Repeat for each character in the file. The end result is English readable text. Design a Decryption class to model the decryption process as outlined in step 3. Your Decryption class needs a Process function CallBack, as each encrypted file is encrypted differently. The class should also contain a vector for the translated strings.
