cout如何输出数值的二进制格式？(小例子)

#include <cstdlib>#include <iostream>#include <bitset>

using namespace std;

int main(int argc, char *argv[]){            cout<<"Please Input a Number:";    int i;    cin>>i;

    cout<<"binary format of "<<i<<" is "<<bitset<sizeof(int)*8>(i)<<endl;

        system("PAUSE");    return EXIT_SUCCESS;}

运行环境为dev c++.
