Struct with char vector

Question

So guys, I created this struct

typedef struct{
    int inicio;
    int tamanho;
    int fim;
    char *elementos[50];
}Fila;

And I intend to create a char vector, just as I have created several times an integer vector. Only it is not working at the time of implementation of the queue creation function.

Fila* criarFila(int tamanho){
    Fila* novaFila = new Fila;
    novaFila->tamanho = tamanho;
    novaFila->inicio = -1;
    novaFila->fim = -1;
    novaFila->elementos = new char[tamanho];

    return novaFila;
}

When it comes to compiling, it makes the mistake:

listar.cpp:66:22: error: incompatible types in assignment of ‘char*’ to   ‘char* [50]’
  novaFila->elementos = new char[tamanho];
                      ^

Does anyone understand why you are making this mistake?

Answer 1

char *elementos[50];

So you are creating an array of 50 char pointers. Probably what you want is just a pointer (then the new char[size] will work):

char *elementos;

Or, if you want a fixed size array:

char elementos[50];

In this case, it will be allocated together with the struct (no need to use new).
