How about this?

int i, j;
for (i = 0; i < tamanho; i++) {
    for (j = 0; j < 10; j++) {
        printf("%d ", p[i][j]);
    }
}

Note that in the first pair of brackets, we access a position in the array, which results in a pointer. With the second pair of brackets, we access the position of the array from the resulting pointer.
