1. (25 pts.) Consider the following C+ program. Assume that all the function calls are independent that is no function call affects other functions' calls for each of the parameter passing method void swap(int a, int b); int temp = a; b = temp; int main() int value = 2, list[5] = {1, 3, 5, 7, 9); swap(value, list[0]); swap(list[O], list[1D: swap(value, list[value]); What are the values of the variables value and list after each of the parameter-passing three calls to swap for each of the following methods? value list a) Pass-by-value: swap(value, list[0]) swap(list[0], list[1]) swap(value, list[value]) swap(value, list[O]) swap(list[0], list[]) swap(value, list[value]) b) Pass-by-reference c) Pass-by-value-reference: swap value, list[0) swap(list[0], list[I]) swap(value, list[value])
