bitset中提供的成员函数中没有加法这些的操作，自己要实现加1操作，就想了个比较简单而笨的方法，其实就是利用bitset可以使用unsigned long类型值初始化这条性质实现的。

#include <iostream>

#include <bitset>

using namespace std;

void main()

{

int i=0;

const int bitnum=4;

unsigned long u=0;

while(i<=15)

{

bitset<bitnum> bitvec(u);

cout<<bitvec<<" "<<bitvec[0]<<" "<<bitvec[3]<<endl;

u++;

i++;

}

输出结果示例：
