+> **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;
+}
+```
