Chapter 7.3, Problem 19STE

Following is the declaration for an alternative version of the function search defined in Display 7.12. In order to use this alternative version of the search function, we would need to rewrite the program slightly, but for this exercise all you need to do is to write the function definition for this alternative version of search.

  bool search (const int a[], int numberUsed,

  int target, int& where);

//Precondition: numberUsed is <= the declared size of the

//array a; a[0] through a[numberUsed – 1] have values.

  //Postcondition: If target is one of the elements a[0]

  //through a[numberUsed – 1], then this function returns

  //true and sets the value of where so that a[where] ==

  //target; otherwise this function returns false and the

  //value of where is unchangad.
