Set& operator + Set right ) 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 Sets1,s2,s3,s4,s5; int index, equal;/构造集合 for( int k=0; k< 10; k++) 集合赋值 &sl. AddMember(k); s2. AddMember(k+7); ∥ls1:{0,1,2,…,9},s2:{7,8,9,,,16}Set& operator + ( Set & right ); 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; //构造集合 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 }
