• 迭代器iterator正向遍历set集合元素

#include

using namespace std;

int main(){
    sets;
    // write your code here......
    for (int i = 0; i < 5; i++) {
        int temp = 0;
        cin >> temp;
        //插入元素在set集合中
        s.insert(temp);
    }

    //开始遍历
    for (set::iterator it = s.begin(); it != s.end(); it++) {
        cout << *it << " ";
    }

    return 0;
}
