让数组a的exp值从小到大排列,应该如何修正程序 要修正程序让数组a的exp值从小到大排列,可以按照以下步骤进行修正:
1. 在开始部分添加必要的头文件:
#include <stdio.h>
#include <stdlib.h>
2. 修正结构体node_st中的定义错误:
struct node_st {
int coef;
int exp;
struct node_st* next;
};
3. 在list_create函数中,修正np结构体的coef和exp赋值错误,并删除多余的代码:
struct node_st *list_create(int a[], int size) {
struct node_st *p = malloc(sizeof(struct node_st));
if (p == NULL)
return NULL;
p->next = NULL;
struct node_st *cur = p;
int i;
for (i = 0; i < size; i++) {
struct node_st *np = malloc(sizeof(struct node_st));
np->coef = a;
np->exp = i;
np->next = NULL;
cur->next = np;
cur = np;
}
return p;
}
4. 在list_display函数中,删除错误的for循环中的冗余变量i:
void list_display(struct node_st *p) {
struct node_st *cur = p->next;
while (cur != NULL) {
printf("(%d, %d) ", cur->coef, cur->exp);
cur = cur->next;
}
printf("\n");
}
5. 在list_order函数中,修正链表排序的错误:
struct node_st *list_order(struct node_st *p) {
struct node_st *ex;
struct node_st *cur;
struct node_st *next;
ex = p->next;
cur = ex->next;
while (cur != NULL) {
next = cur->next;
if (cur->exp < ex->exp) {
p->next = cur;
cur->next = ex;
ex->next = next;
} else {
ex = ex->next;
}
cur = next;
}
return p;
}
6. 在main函数中修正变量的初始化方式,并在程序结束时手动释放内存:
int main() {
int a[] = {8,9,3,7,6};
int b[] = {4,5,-7,10};
int size_a = sizeof(a) / sizeof(a);
int size_b = sizeof(b) / sizeof(b);
struct node_st *p1, *p2;
p1 = list_create(a, size_a);
p2 = list_create(b, size_b);
// 排序链表p1
p1 = list_order(p1);
list_display(p1);
list_display(p2);
list_free(p1);
list_free(p2);
return 0;
}
经过以上修正后,程序能够按照exp的从小到大顺序输出链表p1的coef和exp值。
