namespace wind{
    float second_number;
}
int main(){
    int choice;


    std::cout<<"Input first number: ";
    std::cin>>window::first_number;


    std::cout<<"Input second number: ";
    std::cin>>wind::second_number;


    std::cout<<"Do you want to 1. Add or 2. Multiply? (1 or 2): ";
    std::cin>>choice;


    if(choice == 1)
        std::cout<<window::first_number<<" + "<<wind::second_number<<" = "<<window::first_number + wind::second_number<<std::endl;
    else if(choice == 2) 
        std::cout<<window::first_number<<" x "<<wind::second_number<<" = "<<window::first_number * wind::second_number<<std::endl;
    else std::cout<<"Invalid choice.";
    return 0;
