I’m having trouble developing a chain list, so please help me. Every time I try to compile error appears on line 7 [Error] Storage size of 'mylist' isn’t known

I’ve already changed the place structure, I’ve fucked everything but still having trouble

Main file. c

#include <stdio.h>
#include <stdlib.h>
#include "lista.h"

void main () {

    struct ListaSimplesEnc minhaLista;

    criarLista(&minhaLista);

    int valor, op;

    while( 1 ){

        printf( "1 - Inserir elemento no inicio\n" );
        printf( "2 - Inserir elemento em ordem (so se a lista estiver ordenada)\n" );
        printf( "3 - Remover elemento no inicio\n" );
        printf( "4 - Remover elemento\n" );
        printf( "5 - Mostrar lista\n" );
        printf( "6 - Sair\n" );
        printf( "Opcao? " );
        scanf( "%d", &op );

        switch( op ){

            case 1: // inserir elemento no inicio

                printf( "Valor? " );
                scanf( "%d", &valor );
                inserirIni(&minhaLista, valor);
                break;
            case 2: // inserir elemento ordenado
                printf( "Valor? " );
                scanf( "%d", &valor );
                inserirOrd(&minhaLista, valor);
                break;
            case 3: // remover o primeiro
                break;
            case 4: // remover determinado elemento
                break;
            case 5: //  mostrar lista
                if (estaVazia(&minhaLista)) {
                    printf("Lista vazia");
                }

  • you need to give details, no one will be able to guess the problems...

  • @zentrunix Every time I try to compile the error "Error [Warming] 'struct Listasimlesenc' declared Inside Parameter list" appears. , I’ve changed the place structure, I’ve noticed everything but still having trouble

  • you have to put the explanations and details (e.g. which line is giving error ? which font is giving error ?) in the question, and not in the comments

    Declare your structs in the file . h

  • that’s not how this site works...you do the program, and when you have a specific difficulty you ask here about that specific difficulty...then usually someone will appear to help...but it has to be a specific problem because this is not a mentoring site

You need to declare the structures in . h and not us . c.

Example:

List file. c

#include <stdio.h>
#include <stdlib.h>
#include "lista.h"

// struct Nodo
// {
//   int info;
//   struct Nodo *prox;
// };

// struct ListaSimplesEnc
// {
//   struct Nodo *prim;
// };

struct ListaSimplesEnc minhaLista;

// ...
// ...

List file. h

struct Nodo
{
  int info;
  struct Nodo *prox;
};

struct ListaSimplesEnc
{
  struct Nodo *prim;
};

extern struct ListaSimplesEnc minhaLista;

// ...

  • thank you very much, I made the change and it worked!

  • then please mark my answer as accepted
