    int y{}; // define variable y to hold user input 2

    std::cin >> x >> y; // get input 1 and input 2 and store in x/y variable respectively, here we use the extraction operator ">>", it is used e.g. when getting user input

/* Best Practice:
     There’s some debate over whether it’s necessary to initialize a variable immediately before you give it a user provided value via another source (e.g. std::cin), since the user-provided value will just overwrite the initialization value. In line with our previous recommendation that variables should always be initialized, best practice is to initialize the variable first.
