Re: output hex bytes to binary file

I am trying to write hex bytes to a binary file.
I have no problem doing this if I use hard coded values like this;

#include <fstream.h>
ofstream OutputFileStream ;
OutputFileStream.open("binaryfile.bin", ios::binary) ;
OutputFileStream << '\xF6' ;
OutputFileStream.close() ;

But what I really want to do is the same thing using variables.
And this is where I can't get it to work.
If I use this;
#include <fstream.h>
int intF7 = 0xF7 ;
ofstream OutputFileStream ;
OutputFileStream.open("binaryfile.bin", ios::binary) ;
OutputFileStream << hex << intF7 ;
