[Dev-C++] Question about bit representation

[Ioannis V. <iv...@em...>]

In a newsgroup out there there was a girl who wanted to see the
representation of a given double in her system. All others provided low
level messy stuff involving & operators etc.


I provided the code:


#include <iostream>
#include <bitset>
#include <limits>


int main()
{
 using namespace std;

 double d=3D1;

 unsigned char *p=3Dreinterpret_cast<unsigned char *>(&d);

// There are systems where 1 byte is more than 8 bits
 bitset<numeric_limits<unsigned char>::digits> byte;

 for(unsigned i=3D0; i<sizeof(d); ++i)
 {
   byte=3Dp[i];

   for(unsigned j=3D0; j<byte.size(); ++j)
      cout<<byte[j];=20
 }
=20
 cout<<endl;
}


However it seems to be printed in the opposite way (try making d an =
unsigned
char). Perhaps it is the way it is implemented in the system, or I am =
taking
something in the opposite way that I can't find out?
