Consider the following program segment to swap two variables a and b using a third variable. The statements are jumbled. Arrange them in the correct order to perform the swap successfully:


void swap(int a, int b)
{
    a = b;      // (1)
    b = t;      // (2)
    int t = 0;  // (3)
    t = a;      // (4)
}

A (a) (1) → (2) → (3) → (4)
B (b) (3) → (4) → (1) → (2)
C (c) (1) → (3) → (4) → (2)
D (d) (2) → (1) → (4) → (3)

Answer: B

Explanation:

We are asked to swap two variables a and b using a third variable t. Let's carefully analyze the correct sequence.

The standard swapping logic using a temporary variable t is:

Declare t → int t = 0;
Store a in t → t = a;
Assign b to a → a = b;
Assign t to b → b = t;

So, the correct order of statements:

int t = 0; → t = a; → a = b; → b = t;

Looking at the labels given in the question:

a = b; → (1)
b = t; → (2)
int t = 0; → (3)
t = a; → (4)

Mapping to our logic: 3 → 4 → 1 → 2 ✅

Answer: (b) (3) (4) (1) (2)
