Give the output of the following program segment:
int x[]={2,45,7,67,12,3};
int i, t=0;
for(i=0, t=5;i<3;i++,t--)
{
System.out.println(x[i]+x[t]);
}

Output
5
57
74
Explanation
1. Array x = [2, 45, 7, 67, 12, 3].
2. Initial values: i = 0, t = 5.
3. Loop condition: i < 3 (loop runs for i = 0, 1, 2)
Iteration 1:
i = 0, t = 5x[0] + x[5] = 2 + 3 = 5- Print:
5 - After iteration:
i = 1, t = 4
Iteration 2:
i = 1, t = 4x[1] + x[4] = 45 + 12 = 57- Print:
57 - After iteration:
i = 2, t = 3
Iteration 3:
i = 2, t = 3x[2] + x[3] = 7 + 67 = 74- Print:
74 - After iteration:
i = 3, t = 2
Loop ends because i is now 3 (not less than 3).
4. So the output is:
5
57
74
