std::cout << '\n'; // use std::sort to sort an array in C++11: std::begin/std::end std::sort(std::begin(myints), std::end(myints)); for (int i = 0; i < 8; ++i) { std::cout << " " << myints[i]; } std::cout << "\n
Array after sorting : 9 8 7 6 5 4 3 2 1 0 还可以在自己定义排序的方式: // A C++ program to demonstrate // STL sort() using // our own comparator #include <bits/stdc++.h> using namespace std; // An interval has a start // time and end time struct Interval { int start, en...
STL几乎封装了所有的数据结构中的算法,从链表到队列,从向量到堆栈,对hash到二叉树,从搜索到排序,从增加到删除...可以说,如果你理解了STL,你会发现你已不用拘泥于算法本身,从而站在巨人的肩膀上去考虑更高级的应用。 排序是最广泛的算法之一,本文详细介绍了STL中不同排序算法的用法和区别。 1 STL提供的Sort算法...
basically we sort the 1D array in//descending order(the last row)sort(two_D_vector[2].begin(), two_D_vector[2].end(), greater<int>());//print the 2D vectorcout<<"printing the 2D vector after sorting\n";
重载运算符之后,可以在sort函数中通过less或greater或less_equal等来调整升序还是降序,默认是升序。 另外,重载运算符后,函数bool operator < 就不要了,否则用g++编译出错。 #include<algorithm> #include<iostream> #include<vector> usingnamespacestd;
CPP // A C++ program to demonstrate // STL sort() using // our own comparator #include<bits/stdc++.h> usingnamespacestd; // An interval has a start // time and end time structInterval{ intstart,end; }; // Compares two intervals ...
使用lambda 替代预制函数对象: cpp sort(v.begin(), v.end(), [](const MyClass& a, const MyClass& b) { return a.value < b.value; }); 4. 总结 默认排序:std::sort() 默认按升序排列。 自定义排序:通过 comp 指定比较规则,支持函数指针、lambda、或标准库函数对象。 预制比较函数:std::less,...
