Let's walk through the code step by step to see what total ends up being.

First, the variables are initialized as end = 5, total = 0, and i = 1.

The while loop runs as long as i < end. At each iteration, total is increased by i, and i is incremented by 2.

Iteration 1:
- Check: is i < end? 1 < 5 → true
- Operation: total += i → total = 0 + 1 = 1
- Update: i += 2 → i = 3

Iteration 2:
- Check: 3 < 5 → true
- Operation: total += i → total = 1 + 3 = 4
- Update: i += 2 → i = 5

Iteration 3:
- Check: 5 < 5 → false
- Loop ends

The final value of total after the loop ends is 4.
