The management of large amounts of data is a headache for many programmers. It is difficult to find a table that is fast, efficient, and supports large-scale data. Based on version 1.0, Qicheng spent a lot of money to write this revised version that strengthens data insertion and deletion. Qicheng dynamic array is a powerful list-shaped data management linked list. It can easily realize random insertion, deletion, modification, and other operations of large amounts of data. Another feature is that it is extremely fast and has high memory utilization. The management of large amounts of data will inevitably require a large amount of memory space. If the size of the space occupied by these data changes with various conditions, we cannot use arrays to manage these data (I won\'t say more about the reason). At this time, we need a dynamic array. MFC provides a good dynamic array class CArray. For a small amount of data, using CArray is good enough, but for a large amount of data (10W level), it is not enough, because its essence is an array, but it has a complex packaging for commonly used operations such as insertion and deletion. In order to solve this problem, Qicheng dynamic array pioneered the ingenious combination of linked lists and arrays, which has the advantages of high-speed random indexing of arrays and the characteristics of flexible and changeable data volume of linked lists.
