数据结构线性表顺序表c语言的实现，顺序表表示的是用一组地址连续的存储单元依次存储线性表的数据元素，所以顺序结构的实现一般采用数组的方式来实现，存储空间也采用动态分配的方式。在定义中用一个ElemType * elem表示基地址，int length 表示当前长度，int listsize表示数组的大小。(Linear table data structure to achieve the order form of the C language, the order of the table is expressed by a set of contiguous memory storage unit in order of the linear table data elements, so the realization of sequence structure generally use the array to realize the dynamic allocation of storage space, but also the way. In the definition, a ElemType * elem is used to represent the base address, int length represents the current length, and int listsize denotes the size of the array.)
