Consider the following program written in C syntax:
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;
}
For each of the following parameter-passing methods, what are all
of the values of the variables value and list after each of the three
calls to swap?
a. Passed by value
b. Passes by reference
c. Passes by value-result
Assume the calls are not accumulative; that is, they are always
called with the initialized values of the variables, so their effects are
not accumulative.
