在STL标准容器中,只有vector,string,deque可以使用sort的。 以vector为例: #include<iostream>#include<algorithm>#include<vector>usingnamespacestd;boolcmp(inta,intb) {returna>b; }intmain() { vector<int>vi; vi.push_back(3); vi.push_back(1); vi.push_back(2); sort(vi.begin(),vi.end(),...
a、若需对vector, string, deque, 或 array容器进行全排序,你可选择sort或stable_sort; b、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. c、若对于vector, string, deque, 或array容器,你需要找到第n个位置的元素或者你需要得到top n且不关系top n中的内部顺...
代码如下: #include"stdafx.h"#include<iostream>#include<string>#include<algorithm>#include<fstream>usingnamespacestd;intcmp0(char& a,char& b){returna>b; }intcmp1(char& a,char& b){returna<b; }voidReorderOneTime(inta,ints,inte,char* str){if(a==0) {sort(str +s-1, str+ e , cmp0...
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...
return aFirstPart < bFirstPart; } } void MainFramework::groupStrips() { for(const QString& fileName : m_colorCAllFiles) { if(fileName.contains("_04_")) { m_colorCfiles04.append(fileName); } else if(fileName.contains("_02_")) { ...
struct Person {std::string name;int age;};bool comparePersons(const Person& a, const Person& b) {return a.name < b.name; // sort by name in ascending order} 然后,我们可以使用这个函数与sort算法一起,对Person对象的std::vector进行排序: ...
Use thestd::sortAlgorithm to Sort the String of Characters in C++ In this article, we assume that the sequence of characters is stored in astd::stringobject. Since thestd::stringclass object is iterable, we can call any range-based STL functions on it. In this case, we use thestd::so...
int main(){ list<string> ls = {"one", "two", "three"}; ls.sort([](const string& a, const string& b){ return a < b; }); for(string item: ls) cout << item << " "; return 0; } // out /* one three two */ 原文链接 C++中使用sort对常见容器排序 -QT开发中文网qt...
int a[20]={2,4,1,23,5,76,0,43,24,65},i; for(i=0;i<20;i++) cout<<a[i]<<endl; sort(a,a+20,greater<int>()); for(i=0;i<20;i++) cout<<a[i]<<endl; return 0; } 4)既然有迭代器,如果是string 就可以使用反向迭代器来完成逆序排列,程序如下: ...
string name; // 年龄 int age; // 国籍 string country; }; /** * 定义排序规则,函数返回true的时候,关系表达式的左数将会排在数组靠前的位置 * 参数为两个运动员对象 * @return */ bool cmp(athleth a,athleth b){ //两个字符串比较大小时,是从左往右逐个比较ASCII码 ...
