#include<vector> #include<iostream> using namespace std; typedef struct rect { string name; int id; int length; int width; //对于向量元素是结构体的,可在结构体内部定义比较函数,下面按照id,length,width升序排序。 bool operator< (const rect &a) const { if(id!=a.id) return id<a.id; els...
std::vector<int> values{3, 5, 4, 4, 5, 1}; std::sort(values.begin(), values.end()); for (auto v : values) std::cout << v << std::endl; return 0; } 只是std::sort(values.begin(), values.end());这样简简单单的一句就完成了vector数据从小到达的排序,运行结果如下: albert@h...

begin(), vec.end()); // 使用std::sort进行排序 // 打印排序后的vector for (int num : vec) { std::cout << num << " "; } std::cout << std::endl; return 0; } 运行这段代码后,你将看到输出为1 2 5 5 6 9,这验证了std::vector已经成功按照升序排序。
