C++ Vector 练习

练习 Vector 的使用 

 读入若干个数字,然后对其进行从大到小排序,依次输出这些数字,并且输出它们的个数

#include <iostream>
#include <algorithm>

using std::vector;
using std::cin;
using std::cout;
using std::greater;
using std::endl;

int main(){
    
    vector<int> v;
    int input;
    while(cin >> input){
        auto iter = find(v.begin(), v.end(), input);
        if(iter == v.end()){
            v.push_back(input);
        }
    }
    
    sort(v.begin(), v.end(), greater<int>());
    for (int i = 0; i < v.size(); i++){
        cout << v[i] << endl;
    }
    
    cout << v.size() << endl;
    return 0;
}
