Void InitStack (LinkStackPtr * L)
It seems to need not add *
Have you added in the typedef

CodePudding user response:

StackNode, * LinkStackPt;

The former is a structure type and the latter is a structure pointer type

Changed after they lose everything not to come out...

CodePudding user response:

(* L)=(LinkStackPtr) malloc (sizeof (StackNode));
When allocating memory need not * L, L just put directly

L do not add *, add a * after you in brackets LinkStackPtr try

oh, I can't see structure there has added a *...
