Continue statement in Go - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the continue statement do in a Go loop?

It skips the rest of the current loop iteration and moves to the next iteration immediately.

beginner

In which types of loops can you use the continue statement in Go?

You can use continue in for loops, including traditional, range-based, and infinite loops.

intermediate

What happens if you use continue inside a nested loop in Go?

The continue statement affects only the innermost loop where it is called, skipping to the next iteration of that loop.

beginner

Example: What will be printed by this Go code?<br>

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

The numbers 1, 2, 4, and 5 will be printed each on a new line. The number 3 is skipped because of the continue.

advanced

How can you use continue with a label in Go?

You can use continue with a label to skip to the next iteration of an outer loop by writing continue labelName.

What does the continue statement do inside a Go for loop?

A Skips the rest of the current iteration and starts the next iteration

B Exits the loop completely

C Pauses the loop until user input

D Restarts the entire program

The continue statement skips the remaining code in the current loop iteration and moves to the next iteration.

In Go, where can you NOT use the continue statement?

A Inside a nested <code>for</code> loop

B Inside a <code>for</code> loop

C Inside a <code>switch</code> statement

D Inside a range loop

continue is only valid inside loops like for. It cannot be used inside switch statements.

What will happen if continue is used inside the inner loop of nested loops without a label?

A It causes a compile error

B It skips to the next iteration of the inner loop

C It exits both loops

D It skips to the next iteration of the outer loop

Without a label, continue affects only the innermost loop where it is used.

How do you skip the rest of the current iteration of an outer loop in Go?

A Use <code>continue</code> with the outer loop's label

B Use <code>break</code> with the outer loop's label

C Use <code>goto</code> statement

D Use <code>return</code> statement

Using continue labelName skips to the next iteration of the labeled outer loop.

What will this code print?<br>

for i := 1; i <= 3; i++ {
  for j := 1; j <= 3; j++ {
    if j == 2 {
      continue
    }
    fmt.Printf("%d,%d\n", i, j)
  }
}

A Only pairs where j is 2

B No output

C Only pairs where i is 2

D All pairs except those where j is 2

The inner loop skips printing when j equals 2, so all other pairs are printed.

Explain how the continue statement works in Go loops and give an example.

Think about how to skip some steps in a loop without stopping it.

Describe how to use labeled continue in nested loops in Go and why it might be useful.

Labels help control which loop to continue in nested loops.
