2. Sorting in Descending Order We can also sort a data structure using thesort()function indescendingorder by manipulating its third parameter. Let us see how. In the code below we have used thestd::greater<int>()function which acts exactly the opposite way thestd::less<int>()function do...
// C++ program to demonstrate descending order sort using // greater<>(). #include <bits/stdc++.h> using namespace std; int main() { int arr[] = { 1, 5, 8, 9, 6, 7, 3, 4, 2, 0 }; int n = sizeof(arr) / sizeof(arr[0]); sort(arr, arr + n, greater<int>());...
list1.push_back( Salesperson( "C", 48500, 1 ) ); // sort District 1 salespeople in descending order and display list1.sort( greater<Salesperson>() ); for_each( list1.begin(), list1.end(), mem_fun_ref( &Salesperson::print ) ); } 引用:http://www.java2s.com/...
// C++ program to demonstrate descending order sort using // greater<>(). #include<bits/stdc++.h> usingnamespacestd; intmain() { intarr[]={1,5,8,9,6,7,3,4,2,0}; intn=sizeof(arr)/sizeof(arr[0]); sort(arr,arr+n,greater<int>()); cout<<"Array after sorting : "; for(...
How to Sort an Array in Descending order using STL in C++? It is a built-in function ofalgorithmheader file it is used to sort the containers like array, vectors in specified order. To sort elements in Descending order, we need to pass a function as third parameter, we can usegreater<...
// C++ program to demonstrate descending ordersortusing// greater<>().#include<bits/stdc++.h>usingnamespacestd;intmain(){intarr[] = {1,5,8,9,6,7,3,4,2,0};intn =sizeof(arr)/sizeof(arr[0]);sort(arr, arr+n, greater<int>());cout<<"Array after sorting:\n";for(inti =0;...
是使用STL的sort排序自己的类,其实就是传入sort的第三个参数,具体由三种方法,分别是: 1.定义普通函数 2.定义函数对象 3.重载 "<" 代码如下: 定义排序函数: bool Less(const Student& s1, const Student& s2) { return s1.name < s2.name; //可以自己设定 ...
C++ std::map items in descending order of keys 我如何使用std :: map容器,其键值按降序排列。 例如,如果插入以下项目: 1 2 3 [2,5] [1,34] [3,67] 它们将在地图中按以下顺序排序: 1 2 3 position0:[1,34] position1:[2,5] position2:[3,67] ...
So if we sort the first row in descending order the output will be: [[3, 5, 4], [6, 4, 2], [7, 3, 1]] Example #include <bits/stdc++.h>usingnamespacestd;voidprint(vector<vector<int>>two_D_vector) {for(autoit:two_D_vector) {//it is now an 1D vectorfor(autoij:it) {...
In C++, sorting string is done using two ways one with using some of the sorting techniques and another to use in-built STL Library that is provides by C++. Sorting strings is just as arranging the given strings in a specified order such as ascending order or descending order. Now let us...
