从小到大排序比较简单,使用sort()函数既可,sort的头文件是#include<algorithm>
从小到大
#include <iostream> #include <vector> #include <algorithm> using namespace
std; int main() { int a[] = {8,6,2,9,3,5,4,1,7,10}; vector<int> arr(a, a+5);
sort(arr.begin(),arr.end()); for(int i = 0; i <arr.size(); ++i){ cout <<arr[i]
<< " "; } return 0 ; }
从大到小
方法一:sort默认排序从小到大,但可以自己写函数或者使用greater<int>(),或者自定义排序规则
#include <iostream> #include <vector> #include <algorithm> using namespace
std; int main() { int a[] = {8,6,2,9,3,5,4,1,7,10}; vector<int> arr(a, a+5);
sort(arr.begin(),arr.end(),greater<int>()); for(int i = 0; i <arr.size(); ++i){
cout <<arr[i] << " "; } return 0 ; }
或者自己定义函数,大的写在前面
#include <iostream> #include <vector> #include <algorithm> using namespace
std; bool cmp_max(int x,int y){ return x > y; } int main() { int a[] =
{8,6,2,9,3,5,4,1,7,10}; vector<int> arr(a, a+5);
sort(arr.begin(),arr.end(),cmp_max); for(int i = 0; i <arr.size(); ++i){ cout
<<arr[i] << " "; } return 0 ; }
方法二:使用sort排序后,使用reverse()
注:reverse() 的将元素倒置,但不排列
#include <iostream> #include <vector> #include <algorithm> using namespace
std; int main() { int a[] = {8,6,2,9,3,5,4,1,7,10}; vector<int> arr(a, a+5);
sort(arr.begin(),arr.end()); reverse(arr.begin(),arr.end()); for(int i = 0; i
<arr.size(); ++i){ cout <<arr[i] << " "; } return 0 ; }
