test_net missing one case?

[K0IN]

test_net misses one iteration and therefore always displays one misses one (correct) case,

test code:

int main(int argc, char **argv)
{
    float in_0[] = {0, 0};
    float in_1[] = {0, 1};
    float in_2[] = {1, 0};
    float in_3[] = {1, 1};

    float *in[4] = {
        in_0, in_1, in_2, in_3};

    float f[] = {0, 1, 1, 0};

    float *tg[4] = {
        &f[0],
        &f[1],
        &f[2],
        &f[3],
    };

    Dim dim = {4, 2};
    const int n_epoch = 200;

    float J[n_epoch];
    float acc[n_epoch];

    Dim in_size = {4, 5};
    Dim out_out = {5, 1};

    NeuralNet *ann = create_net(in_size, out_out);
    // add_hidden_layer(ann, 10);

    train_net(ann, in, tg, J, acc, dim, n_epoch);

    test_net(ann, in, tg, dim);
    print_net(ann);
    free_net(ann);
}
