Set operator( Set& right Set operator-( Set& right ) int Contains( const int x )3 int SubSet( Set& right ) int operator -- Set& right 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 ); }; 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 }
