Variables can be divided into four categories: static, stack-dynamic, explicit heap-dynamic, and implicit heap-dynamic. For each variable in the C++ program below, specify which category it belongs to. Include both named variables and anonymous variables in your answer. #include using namespace std; int n; int sum fine a[], int n); int main(void) {int i; cout > n; int *a = new int[n]; for (i = 0; i > a[i];} cout
