Warning on battery hands

Question

I’m trying to make a simple stack implementation, however the message appears:

Warning: initialization from incompatible Pointer type -Wincompatible-Pointer-types

This Warning appears on both line 20 and line 29. These pointers are of the same type (no*) and the implementation works correctly. Can someone help me?

Answer 1

Vc defined its Node structure as being:

typedef struct _no {
   int item;
   struct no *prox;
} no;

The right thing would be:

typedef struct no {
   int item;
   struct no *prox;
} no;

Without the underscore
