问题几乎是不言自明的。
这是我的代码：
LinkedList* llSort(LinkedList* l) { // this function is changing the ascii values for some reason
LinkedList* tmpPtr = l; // tmpPtr is pointing to the beginning of the LinkedList
LinkedList* tmpNext = l->next; // tmpNext is pointing to the second entry in the LinkedList
int tmp;
/* while we are not at the end of the LinkedList */
while(tmpNext != NULL) {
/* and while tmpNext isn't pointing backwards */
while(tmpNext != tmpPtr) {
/* if the frequency of tmpNext is less than the frequency of tmpPtr */
if(tmpNext->value->freq < tmpPtr->value->freq) {
/* set tmp = to tmpPtr's freq */
tmp = tmpPtr->value->freq;
/* set tmpPtr's freq equal to tmpNext's freq */
tmpPtr->value->freq = tmpNext->value->freq;
/* set tmpNext's freq equal to tmp, which is the value of the original frequency */
tmpNext->value->freq = tmp;
}
/* set tmpPtr equal to it's next value */
tmpPtr = tmpPtr->next;
}
tmpPtr = l;
tmpNext = tmpNext->next;
}
return tmpPtr;
}
LinkedListsH.h：创建指向HuffmanTrees的指针结构和指向LinkedList中下一个值的指针。
#include "huffman.h"
typedef struct linkedListNode {
HuffmanTree* value;
struct linkedListNode* next;
} LinkedList;\
和HuffmanTree结构。
#include <stdio.h> //printf
#include <stdlib.h> //standard library
#include <string.h>
typedef struct huffmanNode {
char c;
int freq;
struct huffmanNode* left;
struct huffmanNode* right;
} HuffmanTree;
当我运行此代码时，llSort方法正确排序LinkedList，但它也会更改Huffman字符的ascii值。我已经走了几次不同的时间，我无法弄清楚为什么会发生这种情况。有没有人有想法？
谢谢！
