10. What will be the output of the following code: for (int i = 5; i >= 0; --i) { cout << i << " "; if (i == 3) break; } in C++? A. Compilation error B. 5 4 3 C. 5 4 3 2 1 0 D. 5 4 3 0 1 Answer & Solution Discuss in Board Save for Later Answer & Solution Answer: Option C Solution: The given code is a for loop in C++: for (int i = 5; i >= 0; --i) { cout << i << " "; if (i == 3) break; } This loop initializes i to 5 and decrements it in each iteration until i becomes less than 0. On each iteration, it prints the current value of i followed by a space. When i becomes 3, the if condition becomes true and the break statement terminates the loop. Therefore, the values printed are: 5 4 3 No further values (like 2, 1, 0) are printed because the loop exits when i == 3. Hence, the correct output is: 5 4 3
