C#.NET — Follow goto-based loop to find printed range. int i = 0, j = 0; label: i++; j += i; if (i < 10) { Console.Write(i + " "); goto label; }

Introduction / Context:
Although goto is rarely recommended in modern C#, this example demonstrates a manual loop using a label and a conditional jump. The question asks you to trace which values of i are printed before the condition fails.

Given Data / Assumptions:

• i and j start at 0; j accumulates but is irrelevant for printing.
• i is incremented before the check and print.
• Printing occurs only when i < 10.

Concept / Approach:
Observe the sequence: increment i, update j, test i < 10, print i, and loop via goto. Because i is incremented before the test, the printed sequence begins at 1 and ends at 9, stopping when i becomes 10 (which fails the if condition and the jump does not occur).

Step-by-Step Solution:

Verification / Alternative check:
Replace goto with a while: i = 0; while (i < 9) { i++; Console.Write(i + " "); } → prints 1..9.

Why Other Options Are Wrong:

• B includes 0, which is never printed.
• C/D shift the range; the code clearly starts at 1 and stops before 10.
• E: labels and goto are legal; no compile error.

Common Pitfalls:
Expecting 10 to print; the condition prevents printing when i equals 10.

Final Answer:
Prints 1 to 9
