Continue statement in Go - Step-by-Step Execution

Concept Flow - Continue statement

Start Loop

↓

Check Condition

Yes↓

Check if continue condition

↓

Skip rest of loop

↓

Next iteration

↓

End Loop

The loop checks a condition each time. If the continue condition is true, it skips the rest of the loop body and moves to the next iteration.

Execution Sample

Go

for i := 1; i <= 5; i++ {
    if i == 3 {
        continue
    }
    fmt.Println(i)
}

This loop prints numbers 1 to 5 but skips printing 3 using continue.

Execution Table

Iteration	i value	Condition i == 3?	Action	Output
1	1	No	Print 1	1
2	2	No	Print 2	2
3	3	Yes	Continue (skip print)
4	4	No	Print 4	4
5	5	No	Print 5	5
6	6	Loop ends	Exit loop

💡 i reaches 6, condition i <= 5 is false, loop ends

Variable Tracker

Variable	Start	After 1	After 2	After 3	After 4	After 5	Final
i	1	2	3	4	5	6	6

Key Moments - 2 Insights

Why does the number 3 not get printed even though i reaches 3?

Because at iteration 3, the condition i == 3 is true, so the continue statement skips the print action as shown in execution_table row 3.

Does the continue statement stop the entire loop?

No, continue only skips the rest of the current loop iteration and moves to the next one, as seen in execution_table rows 3 and 4.

Visual Quiz - 3 Questions

Look at the execution table, what is the output at iteration 3?

A 3

B No output

C Error

D 0

💡 Hint

Check the 'Output' column for iteration 3 in the execution_table.

At which iteration does the loop stop running?

A 6

B 3

C 5

D 1

💡 Hint

Look at the exit_note and the last row in execution_table.

If we remove the continue statement, what will happen at iteration 3?

A Loop will break

B Nothing changes

C 3 will be printed

D Loop will skip iteration 4

💡 Hint

Refer to the action and output difference in execution_table row 3.

Concept Snapshot

Go continue statement:
- Used inside loops to skip current iteration
- Syntax: continue
- When hit, skips rest of loop body
- Loop continues with next iteration
- Useful to ignore specific cases without breaking loop

Full Transcript

This example shows a Go for loop from 1 to 5. Each time, it checks if the current number i equals 3. If yes, the continue statement skips printing that number and moves to the next loop cycle. Otherwise, it prints the number. The loop stops when i becomes 6 because the condition i <= 5 is false. The continue statement only skips the current iteration, not the whole loop.
