(xix) Consider the following program segment in which the statements are jumbled, choose the correct order of statements to swap two variables using the third variable.
void swap(int a, int b)
{
a=b →(1)
b=t →(2)
int t=0; →(3)
t=a; →(4)
}
(a) (1) (2) (3) (4)
(b) (3) (4) (1) (2)
(c) (1) (3) (4) (2)
(d) (2) (1) (4) (3)

Solution
