Set& operator*( Set& right ) Set& operator-( Set& right ) int Contains( const int x )3 int SubSet( Set& right ) int operator =-( Set& right )3 使用示例 Set sl s2. s3 s4.s5: int index, equal for(intk=0;k<10;k++)/集合赋值 &sl. AddMember( k); s2. AddMember(k+7);) ∥s1:{0,1,2,…,9},s2:{7,8,9,…,16}Set& operator * ( Set& right ); Set& operator - ( Set& right ); int Contains ( const int x ); int SubSet ( Set& right ); int operator == ( Set& right ); }; 使用示例 Set s1, s2, s3, s4, s5; int index, equal; for ( int k = 0; k < 10; k++ ) //集合赋值 { s1.AddMember( k ); s2.AddMember( k +7 ); } // s1 : { 0, 1, 2, …, 9 }, s2 : { 7, 8, 9, …, 16 }
