3. Write the necessary member functions to create a counter class which counts from zero to a maximum then back down to zero. Do not modify the main program. You must write the prototypes and the definitions of the methods of the class. Declaration of Class Updown /* File: updown.h A class representing a simple counter which counts up from 0 to a marimum value and then counts back down to 0 at which point the process repeats */ #ifndef UPDOWNH #define UPDOWNH #include #include using namespace std; class updown { private : int max: int direction; int value: // count cycles between 0 and mar // 1 means count up, O means count down // this is the value stored in the counter public: // you fill in the method prototypes #endif /* UPDOWN.H */ Implementation of Class Updown /* File: updow.cpp Implementation of class updown */ #include "updown.h" In Methods of updown // Main Program Using Class Updown /* File: testupdown.cpp Application program using class updown Programmer: your name Date: #include "updown.h" int main(void) ofstream fout ("updownout.txt"); // prepare the output file updown c(7); // declare a counter object c // the constructor updown (7) is called which sets // c. value = 0, c. direction = 1 and c.masc = 7 */ int i; for (i=1; i
