Problem 1.1: What is the difference between the following two chunks of code:

if (arr1 == arr2) {
	process();
}

if (! memcmp(arr1, arr2, n * sizeof(int))) {
	process();
}

Assuming arr1 and arr2 are both integer arrays of length n. [Solution]

Problem 1.2: Write code that will make a copy of int arr[SIZE] and point the array int arr_new[] to it. [Solution]
