记得,以前翻译过Effective STL的文章,其中对如何选择排序函数总结的很好: 若需对vector, string, deque, 或 array容器进行全排序,你可选择sort或stable_sort; 若只需对vector, string, deque, 或 array容器中取得top n的元素,部分排序partial_sort是首选. 若对于vector, string, deque, 或array容器,你需要找到第...

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...
Whereas std::end() will return a iterator(pointer) to one past the last element in the array we pass it. So we could call the sort function by passing it begin() and end() like so. sort(begin(intArray), end(intArray)); Sorting Vectors and other STL Containers Example Warning: ...
print(two_D_vector);//sorting the 2D array based on a particular row//here we sort the last row of the 2D vector//in descending order//so, 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>())...

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,...
STL容器container containers) GNU2.9版中容器多写为一个单一的类模板,较为简明,容易理解。 GNU4.9版中容器变成了有复杂继承和复合(包含)关系的类模板,不易理解。STL::vector实现及函数STL::arraySTL::list源码及实现STL::deque以及由其实现的queue和stackSTL::rb_tree红黑树以及set,mapSTL::hashtable 参考:侯捷...
