 // Function: frequency

 // Description: Counts the number of times a specific
 //              integer appears in an array.
 //
 // Parameters: theArray - array of integers
 //             n        - number of elements to check
 //             x        - integer to search for
 //
 // Returns:    count - number of times x appears
 //                     in the first n elements
 //
 // ***************************************************
