Consider the following
void main () {
int value = 2, list[5] = {1, 3, 5, 7, 9};
swap (value, list[0]);
swap (list[0], list[1]);
swap (value, list[value]);
}
void swap (int a, int b) {
int temp;
temp = a;
a = b;
b = temp;
}
What are the values of the variables value and list after each of the three calls to
swap if the parameters are passed
(a) by value?
(a) by reference?
