//tp的类型实际是: std::tuple<int&,string&, int&> 1. 再看看如何获取它的值: const char* data = std::get<0>(); //获取第一个值 int len = std::get<1>(); //获取第二个值 1. 2. 还有一种方法也可以获取元组的值,通过std::tie解包tuple int x,y; string a; std::tie(x,a,y) ...
Python 包含6种数据类型,其中Number(数字)、String(字符串)、Tuple(元组)、 List(列表)、Dictionary(字典)、Set(集合); 1.回顾Tuple(元组)的常用方法: Tuple的创建:tuple()方法创建,或者小括号的方式,有时也直接省略小括号 a = tuple(range(10))

方法/步骤 1 头文件在使用这种数据类型需要在开头定义头文件#include<tuple> 2 首先,定义一个tuple类型的对象item。这个对象item中包含两个元素1和“hello”tuple<int ,string > item{1,"hello"};3 通常我们使用get模板函数获取tuple类型变量中的元素。a表示第一个元素,b表示第二个元素,我们使用auto自动获取...
