Q4

 ptr2 = malloc (count * sizeof(char)); ptr = ptr2; }

Which of the following statements are true after the code marked Q4
completes? (select all that are true)
The code results in a 'memory leak'
ptr and ptr2 point to different memory and the values in the array that
ptr2 points to will be copied to the memory that ptr points to.
There are two dynamically allocated arrays in memory.
There is one dynamically allocated array in memory.
both ptr and ptr2 point to the same memory on the heap (dynamic
memory)
The assignment ptr = ptr2 will fail as the arrays are of different sizes.
both ptr and ptr2 point to the same memory on the stack (static memory)
