Write a function for given main functionint * return_an_array(int n) which takes an integer n and returns a pointer to an array (allocated off of the heap in the function) containing the digits of n in the appropriate positions. If n = 0 return 0 (which is the “null” pointer). Recall an array name is just a pointer to the first element of the array. Please use following main to test your function. int main() { int *a = return_an_array(23542); // array of size 5 for(int i=0;i<5;i++) cout<

Question

Write a function for given main functionint * return_an_array(int n)
which takes an integer n and returns a pointer to an array (allocated off of the heap in
the function) containing the digits of n in the appropriate positions. If n = 0 return 0
(which is the “null” pointer). Recall an array name is just a pointer to the first element of
the array.

Please use following main to test your function.
int main() {
int *a = return_an_array(23542); // array of size 5
for(int i=0;i<5;i++)
cout<<a[i]<<" "; // print 2 3 5 4 2
cout<<endl;
delete [] a;
int *b = return_an_array(12345678); // array of size 8
for(int i=0;i<8;i++)
cout<<b[i]<<" "; // print 1 2 3 4 5 6 7 8
cout<<endl;
delete [] b;
return 0;
}
