c - 从字符串中删除标点符号，然后在替换后将其放回原处

Question

我的任务是从两个文件中读取int输入。一个包含一首拼写错误的单词的诗，另一个包含拼写错误的单词的钥匙和紧随其后的正确替换。

我应该用每个文件中的信息填充两个链表，并创建一个解码第一个文件的函数。我需要在链表中使用指针而不是 char 数组，最后程序需要打印第一个文件并进行所有更正。

我一切都很好，直到解码器函数需要比较带有标点符号的单词。我将如何忽略标点符号而不会在最终格式中丢失标点符号。

这是我的解码器函数：

LINK *decoder(TRANS *codet, LINK *head)
{
LINK *currentt;
currentt = head;
TRANS *current;
current = codet;
printf("Decoding...n");
while (currentt != NULL)
{
current = codet;
while (1)
{
if ()
printf("Comparing %s with %s: n", currentt->words, current->word1);
if (!strcmp(currentt->words, current->word1))
{
printf("Replacing...n");
currentt->words = (char*)calloc(strlen(current->word2), sizeof(char));
strcpy(currentt->words, current->word2);
break;
}
current = current->next;
}
currentt = currentt->next;  
}
return head;
}

这是我的其余代码：
