This is not working

for(iCount=0; iCount<PAGESIZE; iCount++)
	{
		rand_no = rand();

	        // Prepare random data

I mean that the file b.b has its contents as "char" and not Hexadecimal.

std::ofstream a("b.b", std::ios::binary|std::ios::trunc);
std::generate_n(std::ostream_iterator<char>(a), 2112, rand);
