CodePudding user response:
Function void delete_ (NODE * p) statement is defined after the min function, lead to don't know min delete_The
Void delete_ (NODE * p)
{
NODE * q;
Q=p - & gt; Next;
P - & gt; data=https://bbs.csdn.net/topics/p-> next -> data;
P - & gt; Next=q - & gt; Next;
Free (q);
}
Move to the top of the min function
Or on the top of the min function to join
Void delete_ (NODE * p);//add function declaration
