1. Briefly describe why pointer arithmetic is useful/beneficial (not just its definition). Additionally, what is the relationship between arrays and pointers? (hint: find a formula and a written explanation) [3 pt]
2. Think about how you calculated the actual difference (in bytes) between two addresses in C without any compiler warnings. Briefly explain why each step was necessary. [3 pt]
3. Notice that the parameters to the function swapInts were both pointers. Explain why this is necessary. What would happen if the parameters were integers? [3 pt]
