public interface IComparab1e {

///

/// Returns a value that indicates the relative order of the pizzas being compared.

/// The return value has these meanings:

/// Less than zero: this instance precedes the argument in the sort order.

/// Zero: this instance is in the same position in the sort order as the argument. /// Greater than zero: this instance follows the argument in the sort order.

/// public int CompareTo(Pizza pizza) ;

How would you change the header of class Pizza to declare that it implements interface IComparab1e?
