18.1.3.Read a binary number into a bitset

#include <bitset>

#include <iostream>

#include <limits>



using namespace std;



int main( )

{

   // Read a binary number into a bitset

   cout << "Enter a binary number: ";

   bitset< numeric_limits<unsigned long>::digits > bits;

   cin >> bits;

   unsigned long decimal_equivalent = bits.to_ulong();

   cout  << "Binary number: " << bits << "\nDecimal equivalent: " << decimal_equivalent;
