Consider the following program written in C-like syntax. Assume that print just prints the indicated values.

Show the output of this program for each of the following parameter passing methods. If there is any ambiguity, make appropriate assumptions and state what they are. Notice that 8 numbers will be printed out.

1.pass-by-value

2.pass-by-value-result

3.pass-by-reference

int i; int a[4]; void swap (int x, int v) x=x-y; main () a[0] = 3 [1] = 2 a[2] = 6; [3] = 0; swap (i,a[i]); print(i, a[o], a[1], a [2]) swap (a[i],a[i]); print(i, a[o], a[1], a [2]) return O
