The break statement immediately exits the nearest loop when executed, skipping remaining iterations and continuing after the loop.

Execution Sample

C Sharp (C#)

for (int i = 0; i < 5; i++) {
    if (i == 3) {
        break;
    }
    Console.WriteLine(i);
}

This code prints numbers from 0 to 2 and stops the loop when i equals 3 using break.

Execution Table

Iteration	i	Condition (i < 5)	Break Condition (i == 3)	Action	Output
1	0	True	False	Print 0	0
2	1	True	False	Print 1	1
3	2	True	False	Print 2	2
4	3	True	True	Break loop
-	-	False	-	Exit loop	-

💡 Loop exits when i == 3 due to break statement.

Key Moments - 2 Insights

Why does the loop stop printing after i reaches 3?

Because at iteration 4 (i=3), the break condition is true, so the break statement exits the loop immediately (see execution_table row 4).

Does the loop check the condition i < 5 after break?

No, the break exits the loop before the condition is checked again, so the loop ends early (see execution_table row 4 and exit_note).

Visual Quiz - 3 Questions

Look at the execution table, what is the value of i when the break statement is executed?

A 3

B 2

C 4

D 5

💡 Hint

Check the 'Break Condition' column in execution_table row 4.

At which iteration does the loop stop executing the body?

A Iteration 3

B Iteration 5

C Iteration 4

D Iteration 6

💡 Hint

See the 'Action' column where 'Break loop' happens in execution_table.

If the break statement was removed, what would be the output?

A 0 1 2

B 0 1 2 3 4

C 3 4

D No output

💡 Hint

Without break, loop runs until i < 5 is false, printing all i values (see variable_tracker).

Concept Snapshot

Break statement in C#:
- Used inside loops to exit immediately.
- Stops loop execution and continues after loop.
- Useful to stop early based on condition.
- Syntax: break;
- Skips remaining iterations once hit.

Full Transcript

This visual execution shows how the break statement works in a C# for loop. The loop starts with i=0 and runs while i is less than 5. Each iteration prints i. When i reaches 3, the break condition becomes true, so the break statement runs and exits the loop immediately. No further iterations happen after that. The variable i changes from 0 to 3 step by step. The key moment is that break stops the loop early, skipping the normal condition check for the next iteration. The quiz questions help check understanding of when break triggers and what output results.
