Print Hexadecimal Numbers Of a File

Hello,
I'm now developing a home project, but before I start, I need to know how can I print the content of a file(*.bin as example) in hexadecimal.

I like to learn, then a good tutorial is very nice too ;)

Best Regards,

x for lowercase hex letters, X for uppercase letters

Google is your friend for all kinds of C and C++ online tutorials.

I'm not sure but I suggest reading every character and then using the printf function with %hhx to print every byte of the file.
for example:
char c
while file has next
c = next character
printf("%hhx", c)

That's what I would try first.

You'd probably want to fread() BUFSIZ bytes at a time ("The value of BUFSIZ is chosen on each system so as to make stream I/O efficient."). Then use printf() as above -- although that might be a little slow depending on how many characters you have.

If Linux:

od -t x1 filename.bin
