>but I'm surprised chensu wasn't more C++ ish.
Right. Honestly, I have been doing Windows GUI programming, so I seldom use those stuff, such as cin, cout. The first idea I came up with immediately was to use the Windows API function wsprintf.

You have to write "I will not use C in C++" 100 times..... :-)
for a more C++ approach you can open the file with an fstream object and read bytes. Then ouput the bytes to another fstream object using the hex i/o manipulator, like
ifstream In("C:\\SOMEFILE.DAT",ios:
ofstream Out("C:\\SOMEFILE.TXT",ios
while (true)
{
unsigned char Chr;
In >> Chr;
if (In.eof()) // If at the end of the file.
break; // Stop the loop.
Out << ios::hex << Chr;
};
Depending on what you want the hex to look like, you might want to add spaces and or/controll the width of the hex numbers pritned.
