Thread: Trouble reading a hex value, displaying via printf and writing to a file

I'm trying to read a file that has hex values. I fread into a buffer, but I'm have trouble displaying the values via printf. Also, when I try to write the buffer, I'm getting one 0.

Any suggestions on how to display a hex value and/or write a hex value to a file, would be appreciated.

Thanks

A can be displayed in hex notation by

printf ("%X", value);

I don't know exactly what you mean by writing a hex value to a file. But perhaps you mean

fprintf (file, "%X", value);
