Помогите с задачей надо написать код на C++

 #include <iostream>
int main()
{
    double x, y;
    while (true)
    {
        std::cout << "x y » ";
        std::cin >> x >> y;
        std::cout << (x*y>1 ? "No": "Yes") << std::endl;
    }
} 

 #include <cmath>
#include <iostream> 
int main() 
{ 
    double x, y; 
    while (true) 
    { 
        std::cout << "x y » "; 
        std::cin >> x >> y; 
        std::cout << ((fabs(x)<=1 && fabs(y)<=1)
           ? "Yes": "No") << std::endl; 
    } 
} 

 #include <cmath> 
#include <iostream> 
int main() { 
    std::cout << "x, y? "; 
    double x, y; 
    std::cin >> x >> y; 
    puts(fabs(x * y) <= 1.0 ? "yes" : "no"); 
}
