> **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.

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