CArray::SetSize 的用法:从未深入了解这些; ---猜想:既然文章中提到,可能会另开辟空间存储,那会不会是因为InsertAt引起的SetSize重新开辟空间导致newElement发生变化??? ---实践(解决方案):为此提前给m_aryPoint设置10个数据预留空间(实际使用中只有这两组数据)( m_aryPoint.SetSize(10); ),这表明再调用Inse...

void InsertAt( INT_PTR nIndex, ARG_TYPE newElement, INT_PTR nCount = 1 ); void InsertAt( INT_PTR nStartIndex, CArray* pNewArray ); 參數 nIndex 的值可能大於的整數索引。GetUpperBound傳回。 ARG_TYPE 指定項目的型別樣板參數在這個中的陣列。
