    std::vector<int> example; 
  
    // check if vector is empty 
    if (example.empty()) 
        std::cout << "Empty Vector\n"; 
    else
        std::cout << "Not Empty\n"; 
  
    // Add elements to the Vector 
    example.push_back(10); 
    example.push_back(20); 
    example.push_back(30); 
    example.push_back(40); 
  
    // check again if vector is empty 
    if (example.empty()) 
        std::cout << "Empty Vector\n"; 
    else
        std::cout << "Not Empty\n";
