1. Having to check the return function of malloc (or any other memory allocation function) each time we call it can be an annoyance. Write a function named my_malloc that serves as a "wrapper" for malloc. When we call my_malloc and ask it to allocate n bytes, it in turn calls malloc, tests to make sure that malloc doesn't return a null pointer, then returns the pointer from malloc. Have my_malloc print an error message and terminate the program if malloc returns a null pointer.

void *my_malloc(size_t n) {
    void *p = malloc(n);
    if (p == NULL) {
	printf("Failed to allocate memory");
	exit(EXIT_FAILURE);
    }
    return p;
}
