关于bitset的用法

[jieao111]

int main ()
{
bitset<5>b;
cout<<b;
return 0;
}
输出的是00000。



我想让它输出0～32
之间32个二进制数（00000～11111），，请问怎么实现

#include "stdafx.h"
// bitset_reset.cpp   msdn上的例子
// compile with: /EHsc
#include <bitset>
#include <iostream>

int main( )
{
   using namespace std;

   bitset<32> b1 ( 13 );// 13 对应的2进制
   cout << "The set of bits in bitset<5> b1(13) is: ( "<< b1 << " )"
        << endl;

   bitset<32> b1r3;
   b1r3 = b1.reset( 2 );// 把 第二位的数字改变 0变成 1 ，1变成0
   cout << "The collecion of bits obtained from resetting the\n"
        << " third bit of bitset b1 is: ( "<< b1r3 << " )" 
        << endl;

   bitset<32> b1r;
   b1r = b1.reset( );//全部置0
   cout << "The collecion of bits obtained from resetting all\n"
        << " the elements of the bitset b1 is: ( "<< b1r << " )"
        << endl;
}

bitset <5>b1( x ); //x= 0,1,2, ... ,31 
bitset <5>b = b1;
