实现对顺序表的初始化，头插，头删，尾插，尾删， 任意下标的删除， 任意下标处的的元素删除，任意下标处的元素插入，任意元素的下标返回，任意下标处的元素返回， 删除某个元素， 删除线性表中的所有元素，对线性表判空处理， 以及检查线性表有几个元素
1.定义一个线性表
所谓的线性表就是一段地址连续的存储单元一次存储数据元素的线性结构，而连续的地址空间采用数组的结构，但数组有静态的也有动态的，这里先讨论静态线性表的实现
由上图可以看出，静态线性表包括了元素以及元素的个数，因此定义一个线性表就是定义一个结构体
7 typedef struct Seqlist8 {9 int size;10 SeqListType data[SeqListMaxSize];11 }SeqList;//定义一个顺序表定义好结构体后便需要对结构体进行初始化了，对其初始化，只需要将其元素的个数设为零即可。
11 void InitSeqList(SeqList* seqlist)12 {13 seqlist -> size = 0;14 }2.对线性表的头插及就是在保证线性表元素个数不超过MAXSIZE的前提下每次将数据插入下标为零的位置处
111 void SeqListPushFront(SeqList* seqlist, SeqListType value)
112 {
113 if(seqlist == NULL)
114 {
115 return;//非法输入
116 }
117 if(seqlist -> size == SeqListMaxSize)
118 {
119 return;//线性表已满
120 }
121 seqlist -> size++;
122 int i = 0;
123 for(i = (seqlist -> size) - 1 ; i > 0; i--)
124 {
125 seqlist -> data[i] = seqlist -> data[i - 1];
126 }
127 seqlist -> data[0] = value;
128 }3.对线性表的头删就是只要线性表不为空，就将先行表的第1号下标的元素到第size - 1号元素一次向前移动
153 void SeqListPopFront(SeqList* seqlist)
154 {
155 if(seqlist == NULL)
156 {
157 return;
158 }
159 if(seqlist -> size == 0)
160 {
161 return;
162 }
163 seqlist -> size--;
164 int i = 0;
165 for(i = 1; i <= seqlist -> size; i++)
166 {
167 seqlist -> data[i -1] = seqlist -> data[i];
168 }
169 }4.对线性表进行尾插，即就是先将线性表的size加1，再定义定义一个计数器让其指向线性表的结尾，每次将新元素出入其末尾即
22 void SeqListPushBack(SeqList* seqlist, SeqListType value)23 {24 if(seqlist == NULL)25 {26 return;//非法输入 27 }28 if(seqlist -> size == SeqListMaxSize)29 {30 return;//线性表已满31 }32 seqlist -> size++;33 seqlist -> data[seqlist -> size - 1] = value;34 }
5.对线性表的尾删很简单，就是将线性表的大小size减1即可
72 void SeqListPopBash(SeqList* seqlist)73 {74 if(seqlist == NULL)75 {76 return;//非法输入77 }78 if(seqlist -> size == 0)79 {80 return;//线性表为空81 }82 seqlist -> size--;83 }6.对线性表的任意位置进行插入和删除
(1)首先在对其插入时必须判断线性表是否已满，以及传来的指针是否为空指针，其次，当删除的时候也必须判断线性表是否为空。当满足以上要求时，再进行插入或者删除才是合理的。在对线性表任意位置插入是及就是定义一个计数其，让其等于要插入的下标，然后将此处的元素以及后面所有的元素都向后移动，最后将需要插入的元素插入到对应的下标位置处。
198 void SeqListInsert(SeqList* seqlist, int pos, SeqListType value)
199 {
200 if(seqlist == NULL)
201 {
202 return;//非法输入
203 }
204 if(pos == 0)
205 {
206 SeqListPushFront(seqlist, value);
207 }
208 if(pos > seqlist -> size)
209 {
210 return;
211 }
212 seqlist -> size++;
213 int i = 0;
214 for( i = (seqlist -> size) - 1; i >= pos + 1; i--)
215 {
216 seqlist -> data[i] = seqlist -> data[i - 1];
217 }
218 seqlist -> data[pos] = value;
219
220 }(2)对线性表任意元素的删除就是先找到这个元素，然后将这个元素后面的所有元素向前一次移动，
428 void SeqListRemove(SeqList* seqlist, SeqListType to_remove)
429 {
430 if(seqlist == NULL)
431 {
432 return;
433 }
434 if(seqlist -> size == 0)
435 {
436 return;
437 }
438 int pos = SeqListFind(seqlist, to_remove);//找到 to_remove的下标
439 if(pos == -1)
440 {
441 return;//没有找到
442 }
443 SeqListErase(seqlist, pos);
444 }7.返回线性表中某个元素的下标即先定义一个计数器，拿着这个元素对线性表进行便利,将这个元素与线性表中的元素进行比较，如果不相等计数器加1，指针后移，直到相等的时候返回i值
381 int SeqListFind(SeqList* seqlist, SeqListType to_find)
382 {
383 if(seqlist == NULL)
384 {
385 return -1;//非法输入
386 }
387 if(seqlist -> size == 0)
388 {
389 return -1;//非法输入
390 }
391 int i = 0;
392 for(i = 0; i < seqlist -> size; i++)
393 {
394 if(to_find == seqlist -> data[i])
395 {
396 return i;
397 }
398 }
399 return -1;
400 }8.删除某个下标对应的元素就是定义一个指针指向该位置，然后将后面的元素一次赋值给前一个元素即可，最后将size减1
249 void SeqListErase(SeqList* seqlist, int pos)
250 {
251 if(seqlist == NULL)
252 {
253 return;
254 }
255 if(pos < 0 || pos >= seqlist -> size)
256 {
257 return;//非法位置
258 }
259 if(seqlist -> size == 0)
260 {
261 return;//线性表为空
262 }
263 int i = 0;
264 for(i = pos; i < seqlist -> size - 1; i ++)
265 {
266 seqlist -> data[i] = seqlist -> data[i + 1];
267 }
268 seqlist -> size--;
269
270 }9.最后利用冒泡排序对其进行排序
518 void Swap(SeqListType* a, SeqListType* b)
519 {
520 SeqListType tmp = 0;
521 tmp = *a;
522 *a = *b;
523 *b = tmp;
524 }
576 int Greater(SeqListType* a, SeqListType* b)
577 {
578 return *a < *b;
579 }
580
581 void SeqListBubbleSortEx(SeqList* seqlist, Cmp Greater)
582 {
583 if(seqlist == NULL)
584 {
585 return;//非法输入
586 }
587 int count = 0;
588 for(count = 0; count < seqlist -> size -1; count++)
589 {
590 int current = 0;
591 for(current = 0; current < seqlist -> size -1 - count; current++)
592 {
593 if(!Greater(&seqlist -> data[current], &seqlist -> data[current + 1]))
594 {
595 Swap(&seqlist -> data[current], &seqlist -> data[current +1]);
596 }
597
598 }
599 }
600
601 }10.计算线性表大小
631 int SeqListSize(SeqList* seqlist)
632 {
633 if(seqlist == NULL)
634 {
635 return;
636 }
637 return seqlist -> size;
638 }11.查看先行表是否为空
676 void TestEmpty()
677 {
678 TESTHEADER;
679 SeqList seqlist;
680 InitSeqList(&seqlist);
681 SeqListPushFront(&seqlist, '1');
682 SeqListPushFront(&seqlist, '6');
683 SeqListPushFront(&seqlist, '3');
684 SeqListPushFront(&seqlist, 'd');
685 SeqListPushFront(&seqlist, 'z');
686 SeqListPushFront(&seqlist, 'l');
687 SeqListPushFront(&seqlist, 'q');
688 SeqListPushFront(&seqlist, 'a');
689 int ret = SeqListEmpty(&seqlist);
690 printf("expected 0, actual %d\n", ret);
691
692 }12.设置下标为 pos 处的元素为 value
299 int SeqListSet(SeqList* seqlist, int pos, SeqListType value)
300 {
301 if(seqlist == NULL)
302 {
303 return 1;
304 }
305 if(pos < 0 || pos > seqlist -> size)
306 {
307 return 1;
308 }
309 seqlist -> data[pos] = value;
310 }13.返回下标为 pos 的元素的值
340 int SeqListGet(SeqList* seqlist, int pos, SeqListType* value)
341 {
342 if(seqlist == NULL)
343 {
344 return 1;
345 }
346 if(seqlist -> size == 0)
347 {
348 return 1;
349 }
350 *value = seqlist -> data[pos];
351 return 0;
352 }14.整体代码
