4503: 【例】set-定义与遍历

#include<bits/stdc++.h>
using namespace std;
int main(){
    //定义长度为0的set
    //set<int> s;
    int a[]={5,1,3,1,2,4};
    //利用数组初始化 set
	set<int> s(a,a+6);
    set<int>::iterator it;
    for(it=s.begin();it != s.end();it++){
        cout<<*it<<" ";
    }
    cout<<endl;
    return 0;
}
