多元数组

/* 多元数组 */

#include<iostream>
#include<map>

void main()
{
    int int1 = 10;
    double double1 = 99.8;
    char ch = 'A';
    char *str = "hellochina";

// 多元数组
    std::tuple<int,double,char,const char*> mytuple(int1,double1,ch,str);
    
    // tuple必须是一个静态数组
    // tuple  配合array vector使用
    auto data0 = std::get<0>(mytuple);
    auto data1 = std::get<1>(mytuple);
    auto data2 = std::get<2>(mytuple);
    auto data3 = std::get<3>(mytuple);
    
    decltype(data0) dataA;// 获取数据类型再次创建
    
    mytuple.swap(mytuple);//  array vector 都有交换的功能 

    std::cout << " " << typeid(data0).name <<  " " << typeid(data1).name << " " << typeid(data2).name << " " << typeid(data3).name << std::endl;

    std::cout << " " << data0 <<  " " << data1 << " " << data2 << " " << data3 << std::endl;

    std::cin.get();
