Please write in C++

A list of 6 integers is input into vector listints. Complete the program to copy only the negative integers to a new vector listNeglnts. Output the number of negative elements, and the negatives list. Ex: For input 5-209-66-4, output is: 3 -2 -66 -4

Answer 1

#include <iostream> 
#include <vector> 
  
using namespace std; 
  
int main() 
{ 
    vector<int> input; 
    vector<int> output; 
    int n,k;
    
    cin>>n;
    for (int i = 1; i <= n; i++) {
        cin>>k;
        input.push_back(k); 
    }
    
    for (int i = 0; i < n; i++){
        if(input[i]<0){
            output.push_back(input[i]);
        }
    }
    
    cout<<output.size()<<endl;
    for(int i = 0;i<output.size();i++){
        cout<<output[i]<<endl;
    }
    
    return 0;
}

Output :

5 -20 9 -66 -4 ليا -2 |-66 4
