Answer 1

#include <iostream>

#include <vector>

std::vector<int> v;

int main(int argc, char* argv[]) {

   while(1) {

   int temp;

   std::cout << "\nEnter a number: ";std::cin>>temp;

   

   if(temp<0) {

       std::cout << "\nEven number(s) is/are:\n---------------------\n";

       for(int i=0;i<v.size();i++) {

           if(v.at(i)%2==0) std::cout << v[i] << " ";

           else continue;

       }

       std::cout << std::endl;

       break;

   }else {

       v.push_back(temp);

   }

}

   return 0;
