Question

In an exercise, I need to compare a certain number of distances and tell which are the smallest and print them out. For this, I have the following function:

void Permuta(FILE *saida, Cidade *C, int *sequencia, int inicio, int termino, int totalViagens, float **distanciasAux)
{
    int i, j;
    totalViagens = TotalViagens(termino);
    if(inicio == termino)
    {
        for(i = 0; i < termino; i++)
            fprintf(saida, "%d\t", sequencia[i]+1);
        fprintf(saida, "= %f\n", Distancia(C, termino, sequencia));

        *distanciasAux = (float *) malloc(totalViagens*sizeof(float));
        float *distancias = *distanciasAux;
        distancias[i] = Distancia(C, termino, sequencia);
        printf("\n%f\n", distancias[i]);
    }
    else
    {
        for(j = inicio; j < termino; j++)
        {
            Troca((sequencia+inicio), (sequencia+j));
            Permuta(saida, C, sequencia, inicio+1, termino, totalViagens, distanciasAux);
            Troca((sequencia+inicio), (sequencia+j));
        }
    }
}

In this function, I make the dynamic allocation as follows, as can be seen above

*distanciasAux = (float *) malloc(totalViagens*sizeof(float));
float *distancias = *distanciasAux;
distancias[i] = Distancia(C, termino, sequencia);
printf("\n%f\n", distancias[i]);

In printing these results, I have the correct distance values. However, to compare these values, I need to do it in another function. This other function can be seen below:

void CriaSequencia(FILE *saida, Cidade *C, int *sequencia, int numeroCidade, int totalViagens)
{
    int i;
    totalViagens = TotalViagens(numeroCidade);
    float *distancias;
    for(i = 0; i < numeroCidade; i++)
    {
        sequencia[i] = i;
    }
    Permuta(saida, C, sequencia, 0, numeroCidade, TotalViagens(numeroCidade), &distancias);
    for(i = 0; i < totalViagens; i++)
        printf("\n%f\n", distancias[i]);
}

I didn’t start the comparison process because I wanted to make sure that the past values are correct. However, when asking to print the values outside the function, all I get are null values (0.000000).

I would like to know why the impression of the correct values is not taking place and what may be generating this problem.
