C program calculates checksums

To ensure data integrity, it is wise to frequently calculate file checksums. A C program is presented which calculates the checksum of a file using a 16-bit CRC (cyclic redundancy check). The program assumes an 8-bit byte size. The routine reads the file as binary and processes one byte at a time.
