I have a practise problem to write a function that takes 3 dim and dynamicly allocates 3d array with those values and then (PART THAT I DONT GET) : fills the 3-dimensional array with multiplication tables. What am I even supossed to do ?? Here's my code :

``````int main()
{
int dimX = 0;
int dimY = 0;
int dimZ = 0;

cout << "Enter a lenght : ";
cin >> dimX;
cout << "Enter widht : ";
cin >> dimY;
cout << "Enter a height : ";
cin >> dimZ;

John_is_3D(dimX,dimY,dimZ);
}

void John_is_3D(int lenght,int width,int height) {

int val=0;
int *** John;
John = new int**[lenght];

for(int x = 0;x < lenght;x++){

John[x] = new int*[width];

for(int y = 0;y < width;y++){

John[x][y] = new int[height];

for(int z = 0;z < height;z++){

John[x][y][z] =
}
}

}

for(int x = 0;x < lenght;x++){

for(int y = 0;y < width;y++){

for(int z = 0;z < height;z++){

cout<< John[x][y][z] << "   ";
}

}
cout << endl<<endl;
}

}
``````

You've sort of started along the right idea. Use 3 nested loops and add the multiplication product to the array in the innermost loop:

``````for(int x = 0;x < lenght;x++)
for(int y = 0;y < width;y++)
for(int z = 0;z < height;z++)
John[x][y][z] = x*y*z;
``````
