This can be done in C or C++.You shall develop, test, and deliver a basic hexadecimal file dump program, xbd.

The basic hexdump program will open a regular type file (containing binary or text/ASCII content), read every byte in the file and write both the ASCII hex value for that byte as well as its printable (human-readable) character (characters, digits, symbols) to standard output. For bytes forming non-printable characters, print a . character (a dot/period character, i.e. hex value 2E).

The output should be formatted:

: 123456789ABCDEF

-- Where B0B1 means Byte #0, Byte #1, etc; the 123456789ABCDEF is the char/digit/symbol in human readable form

Example hex output:

0003540: 0504 0675 6e73 6967 6e65 6420 6368 6172 ...unsigned char

0003550: 0008 0107 0000 0131 0675 6e73 6967 6e65 .......1.unsigne

Your program shall also provide an option to print in binary instead of hex. If the binary option is selected, then the output format shall be:

bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb 123456

-- where b means bit; each line has 6 octets with a space in between each octet

e.g. (output format fragment sample):

0003540: 00000101 00000100 00000110 01110101 01101110 01110011 ...uns

0003546: 01101001 01100111 01101110 01100101 01100100 00100000 igned

Note, your hexdump program will only open regular file type (binary or text/ASCII content), you are not required to handle other file types or errors encountered if the user attempted to run your hexdump program on other file types (dir, special, link, pipe).

ill be launched as follows from the shells command line:

edoras% xbd

edoras% xbd b

the first example will cause your xbd program to dump (print) the file specified by in ASCII/hex format, the second example will cause your xbd program to dump (print) the file specified by in binary format.
