分配内存时*list = (link_list)malloc(sizeof(link_node));出现：

插入数据的函数原型int link_insert(link_list list,int i,int val)出现：
list.c:38: error: expected ‘)’ before ‘list’
查询数据函数int get_data(link_list list,int i,int *data)出现如下错误：
list.c:54: error: expected ‘)’ before ‘list’
求解？问题出在哪里呢，我找了很久都没找出问题。求高手帮助！


[解决办法]
list = (link_list*)malloc(sizeof(link_node));

[解决办法]
28行我编译没有出错 
 
其余都是
link_list写成了list.
还有个data没有定义错误.
link_list,list_node都定义在main函数中,是局部定义,其他函数里面使用就会出现未定义错误.

探讨


list = (link_list*)malloc(sizeof(link_node));

[解决办法]
link_list*
