以下是修改后的代码:
```c
#include <stdio.h>
#define MAX 100
typedef struct {
int elem[MAX + 1];
int length;
} Stable;
void creat_seq(Stable *list);
void sort_seq(Stable *list);
int bin_search(Stable *list, int k, int low, int high);
int main() {
Stable table;
Stable *list = &table;
int key;
printf("请输入线性表的长度: ");
scanf("%d", &list->length);
creat_seq(list);
sort_seq(list);
printf("排序后的数据: ");
for (int i = 1; i <= list->length; i++) {
printf("%d ", list->elem[i]);
}
printf("\n请输入查找的值: ");
scanf("%d", &key);
bin_search(list, key, 1, list->length);
return 0;
}
void creat_seq(Stable *list) {
printf("请输入顺序表的内容: ");
for (int i = 1; i <= list->length; i++) {
printf("list.elem[%d].key = ", i);
scanf("%d", &list->elem[i]);
}
}
void sort_seq(Stable *list) {
/*冒泡排序*/
int i, j, flag;
for (i = 1; i < list->length; i++) {
flag = 0;
for (j = 1; j <= list->length - i; j++) {
if (list->elem[j] > list->elem[j + 1]) {
list->elem[0] = list->elem[j + 1];
list->elem[j + 1] = list->elem[j];
list->elem[j] = list->elem[0];
flag = 1;
}
}
if (flag == 0) {
return;
}
}
}
int bin_search(Stable *list, int k, int low, int high) {
/*折半查找法的递归函数*/
int mid;
if (low > high) {
printf("没有找到要查找的值\n");
return 0;
}
mid = (low + high) / 2;
if (list->elem[mid] == k) {
printf("查找成功,list[%d] = %d\n", mid, k);
return mid;
} else if (list->elem[mid] < k) {
return bin_search(list, k, mid + 1, high);
} else {
return bin_search(list, k, low, mid - 1);
}
}
```
修改后的主要变化是:
1. 在结构体中添加了 `int length`,用于记录线性表的长度。
2. 在 `sort_seq()` 函数中修正了冒泡排序算法的实现错误。
3. 在 `bin_search()` 函数中添加了查找成功的输出语句,并在没有找到要查找的值时输出提示信息。
