大家好,我正在尝试创建删除某个数字的函数
从链接列表中具有此编号的所有单元格中删除,但我的删除功能仅删除他到达末尾的第一个单元格,然后返回到主
这是我的代码:
struct num* deleteCell(struct num* point, int numdelete)
{
struct num* tempdelete = point;
if (point == NULL) // found the tail and dont found any match to delete
{
printf("not found\n");
return NULL;
}
else if (point->number == numdelete)// found one to delete
{
tempdelete = point->pNext;
free(point);
}
else// Just keep going
{
point->pNext = deleteCell(point->pNext, numdelete);
}
return tempdelete;
}
(point是指向第一个单元格的指针,numdelete是我要删除的数字)
谢谢帮手!!!

最佳答案
struct num* deleteCell(struct num* point, int numdelete) {
if (point == NULL) {
return NULL;
}
if (point->number == numdelete) {
num* tempdelete = point->pNext;
free(point);
return deleteCell(tempdelete, numdelete);
}
point->pNext = deleteCell(point->pNext, numdelete);
return point;
}
