Question

Which of the following statements correctly frees the memory pointed to by 's' and 'p' in the given C program?

a) free(p);
b) free(p->s); free(p);
c) free(p); free(p->s);
d) free(p->s);

Answer 1

Step-by-step explanation:

sounds free

Answer 2

The correct way to free memory in the C program described is to first use 'free(p->s);' and then 'free(p);', which properly releases all dynamically allocated memory and prevents memory leaks.

Step-by-step explanation:

The original question is asking which statement correctly frees the memory pointed to by 's' and 'p' in a given C program. Without the actual code, it's assumed that 'p' is a pointer to a structure or an object that contains another pointer 's'. The correct way to free the memory would be to first free the memory pointed to by 's', and then free the memory pointed to by 'p'. Therefore, the correct answer would be:
b) free(p->s); free(p);

It's important to first free the memory allocated for 's' before freeing 'p' because once 'p' is freed, the address of 's' is lost, which can lead to a memory leak. This order ensures that all dynamically allocated memory is released properly.
