在C语言中,可以使用sort函数对vector进行排序。下面是一个示例代码: #include <stdio.h> #include <stdlib.h> // 比较函数,用于sort函数的第三个参数 int compare(const void *a, const void *b) { return (*(int*)a - *(int*)b); } int main() { int arr[] = {5, 2, 8, 1, 9}; int...
第一种情形:基本类型,如vector<int>,vector<double>,vector<string>也是可以的 1#include<iostream>2#include<vector>3#include<algorithm>4usingnamespacestd;5intmain(){6vector<int>a;7intn =5;8while(n--){9intscore;10cin >>score;11a.push_back(score);12}13//cout <<" a.end()"<< *a.end...
}voidprintArray(vector<A*>array) {for(inti =0; i < array.size(); ++i) { cout<< array[i]->a1 <<""<< array[i]->a2 <<endl; } cout<<endl; }voidprintArray2(vector<B>array) {for(inti =0; i < array.size(); ++i) { cout<< array[i].b1 <<""<< array[i].b2 <<endl;...
vector<int> vectorValue {5, 3, 4, 1, 2}; std::sort(vectorValue.begin(), vectorValue.end()); for (auto value: vectorValue) std::cout << value << std::endl; std::sort(vectorValue.rbegin(), vectorValue.rend()); for (auto value: vectorValue) std::cout << value << std::en...
将sort方法用到vector和set中能实现多种符合自己需求的排序 首先sort方法可以对静态的数组进行排序 1 #include<iostream> 2 using namespace std; 3 int main(){ 4 int a[10] = { 9, 0, 1, 2, 3, 7, 4, 5, 100, 10 }; 5 sort(a, a +10); ...
Examples of C++ Vector Sort Let’s have a look at the examples and understand how actually a sorting can be done using vector arrays in C++. Example #1 C++ code to demonstrate vector sorting in decreasing order. Code: #include<bits/stdc++.h>usingnamespacestd;intmain(){vector<int>v{21,...
#include <algorithm> #include <iostream> #include <vector> using std::cin; using std::cout; using std::endl; using std::sort; using std::string; using std::vector; struct cpu { string property1; string property2; string property3; int value; } typedef cpu; void printVector(vector<...
2019-12-23 10:56 −基本用法 #include<iostream> #include<vector> using namespace std; void main() { vector<int> a(10,1);//初始化容器,开辟10个单位空间·元素初始化为1... saintdingtheGreat 0 2369 sort用法 2019-11-24 21:44 −1、sort(a,a+7) a表示要排序的首地址,数组名代表的就...
void push_back(); //用于在vector的末尾添加元素 T back(); // 返回vector末尾的元素 void clear(); // 将vector清空,vector大小变为0 其他访问方式: cout<<a[5]<<endl; cout<<a.at(5)<<endl; 以上区别在于后者在访问越界时会抛出异常,而前者不会。
Sorting a C++ 2D vector on a particular row The below example sorts a particular row in the 2D vector. Say for example, the 2D matrix is: [[3, 5, 4], [6, 4, 2], [1, 7, 3]] So if we sort the first row in ascending order the output will be: ...
