Consider the following code in C syntax and assume stack memory allocation for nested scope is used. Recall that a dangling references is a reference to a memory address that was originally allocated, but is now deallocated and that garbage memory is memory that has been allocated on the heap and has not been explicitly deallocated, yet is not accessible by the program.
#include int** x NULL; // memory &x int** W NULL; // memory &w = int main() { int* a = NULL; // memory &a int** c = NULL; // memory &c { int* b NULL; // memory &b (int*) malloc(sizeof(int)); // memory 1 b (int*) malloc(sizeof (int)); // memory 2 = a = = c = &b; b = (int*) malloc(sizeof(int)); // memory 3 = b; a X = C; W = // Location &a; free (b); } // Location 2 return 0; }
1. Draw box and circle diagram.
2. The dangling references at Location 1 are and the dangling references at Location 2 are
3. The memory locations that are deallocated at Location 2 are
