how to dynamically declare a 2-d array in c using type: int(*)[ ]?

I have tried using int**(pointer to a pointer) and int*[](array of pointers) but i am unable to perform the task with pointer to an array.How can we use pointer to an array and malloc function to create an 2-d array in c.

Please provide a sample code:)

void *allocateMemory2DArray(size_t x, size_t y)
{
    int (*array)[x][y];

    array = malloc(sizeof(*array));
    return array;
}

5d array

void *allocateMemory5DArray(size_t x, size_t y, size_t v, size_t q, size_t r)
{
    int (*array)[x][y][z][q][r];

    array = malloc(sizeof(*array));
    return array;
}
