Define the char pointer assignment for ABC c, traverse the not assigned to a char array d, and a qstring STR (d), and then to transform the STR as bytearray containing ar, into a char * e again, was meant to write the first char c through the encryption to sqlite, read and decryption, the results and compared with d array traversal e found, a great god for help
