3d dynamic array c++
To create a 3D dynamic array in C++, follow these steps:
Step 1: Declare the 3D array pointer
int* array3D;
Step 2: Allocate memory for the first dimension
array3D = new int[x_size];
Step 3: Allocate memory for the second dimension
for (int i = 0; i < x_size; i++) {
array3D[i] = new int*[y_size];
}
Step 4: Allocate memory for the third dimension
for (int i = 0; i < x_size; i++) {
for (int j = 0; j < y_size; j++) {
array3D[i][j] = new int[z_size];
}
}
Step 5: Access and modify elements of the 3D array
array3D[i][j][k] = value;
Step 6: Deallocate memory when done
for (int i = 0; i < x_size; i++) {
for (int j = 0; j < y_size; j++) {
delete[] array3D[i][j];
}
delete[] array3D[i];
}
delete[] array3D;
