    Function Prototype

    I'm supposed to write a possible function prototype for the following line of code and y is a double:

    Why would you ever have an "&" right there, and what would the prototype be?

    Given that '&' is the "address-of" operator:
    double x = 0;
    double *x = &x;
    It should be easy to figure out how to change:
    double f (double y);
    into what you want.
