C++ ： 类和两种访问权限的练习

解题思路:

注意事项:

参考代码:

#include<iostream>

using namespace std ;

const int n=3 ;

class MAX

{

         private :

                 int n ;

                 int *a ;

                 int Max ;

         public :

                 void set()

                 {

                         a = new int[n] ;

                         Max = -1 ;

                 }

                 void scan()

                 {

                         for ( int i=0 ; i<n ; i++ )

                         {

                                 cin >> a[i] ;

                                 Max = max ( Max , a[i] ) ;

                         }

                 }

                 void print()

                 {

                          cout << Max << endl ;

                 }

} ;

int main ( )

{

         MAX s ;

         s.set() ;

         s.scan() ;

         s.print() ; 

         return 0 ;

}
