How to Access Array three-dimensional in position 2 c++ - c++

Question

I have a problem to get access to the second position of a three-dimensional array.
See code:
int qtdMosquitos = 2500000;
int altura = 500, largura = 500, i, j, k, qtdMosquitoPorCelula = qtdMosquitos /(altura*largura);
long id = 1;
Mosquito* mosquitos[qtdMosquitos][qtdMosquitos][qtdMosquitoPorCelula];
Mosquito* listaMosquitos[qtdMosquitoPorCelula];
for (i = 0; i < altura; i++) {
for (j = 0; j < largura; j++) {
for (k = 0; k < qtdMosquitoPorCelula; k++) {
Mosquito* mosquito = new Mosquito();
mosquito->setId(id);
mosquito->setState("S");
listaMosquitos[k] = mosquito;
}
mosquitos[i][j] = listaMosquitos;
}
}
Line mosquitos[i][j] = listaMosquitos; displays the following error:
main.cpp|24|error: invalid array assignment|
I understand what error says, but I can not find the cause, we already created the instance of the 3D matrix with the same variable that is created the simple array, variable qtdMosquitoPorCelula.
Could you help me set a value for the 3D array?
As follows: matrix[0][1] = arraySimples;

Answer 1

Since the array in C is the pointer of the first element of the array. Therefore, the code
mosquitos[i][j] = listaMosquitos;
means assigning the pointer of listaMosquitos[0] to mosquitos[i][j][0] which will cause memory issue and the compile will prohibit it.
In the code sample, we can do the same thing with the following code sample:
.....
for (i = 0; i < altura; i++) {
for (j = 0; j < largura; j++) {
for (k = 0; k < qtdMosquitoPorCelula; k++) {
Mosquito* mosquito = new Mosquito();
mosquito->setId(id);
mosquito->setState("S");
listaMosquitos[k] = mosquito;
mosquitos[i][j][k] = mosquito;
}
}
}
