cout/cin的基本使用，输出整数的不同进制表示

#include <iostream>

using namespace std;

int main(int argc, char* argv[])
{
    cout << "请输入一个整数" << endl;

    int i;
    cin >> i;
    cout << "八进制：" << oct << i << ",";
    cout << "十六进制：" << hex << i << ",";
    cout << "十进制：" << i << ",";
    cout << "布尔值：" << boolalpha << (bool)i << endl;

    cin.get();
    cin.get();
    return 0;
}
