C/C++——排序 c++c 语言编程算法 在C/C++中的排序,使用到的函数主要有: sort() qsort() 下面详细分析sort()函数和qsort()函数。 1、sort()函数 sort()是STL中提供的算法,头文件为: #include<algorithm> using namespace std; 函数原型如下: template <class RandomAccessIterator> void sort ( RandomAcces...
如此,我们将C++中的STL泛型算法成功地应用到了Qt Quick中。在英语中,我们可以这样描述这个过程:“I am using the ListProcessor class defined in C++ to sort an array in QML. This is done by calling the processList method of the ListProcessor instance.” (我正在使用在C++中定义的ListProcessor类来对Q...

publicclassDescendingComparer:IComparer<int>{publicintCompare(intx,inty){returny.CompareTo(x);}}``` 在上面的代码中,使用SortedSet对集合中的元素进行排序。可以使用默认的排序算法直接创建SortedSet对象,也可以自定义排序算法来对元素进行排序。 需要注意的是,在使用集合排序时,需要根据实际需求和数据类型选择合...
