Loop control break continue

Context

Inside loops, break terminates the innermost loop. continue skips to the next iteration.

You can also use labels to break out of nested loops.

Example

Use break, continue, and a label.

Code example

package main

import "fmt"

func main() {
    // continue
    for i := 0; i < 5; i++ {
        if i%2 == 0 {
            continue
        }
        fmt.Print(i, " ")
    }
    fmt.Println()

    // break
    for i := 0; i < 10; i++ {
        if i == 3 {
            break
        }
        fmt.Print(i, " ")
    }
    fmt.Println()

    // label to break out of two loops
outer:
    for i := 0; i < 3; i++ {
        for j := 0; j < 3; j++ {
            if i == 1 && j == 1 {
                break outer
            }
            fmt.Printf("(%d,%d) ", i, j)
        }
    }
    fmt.Println()
}

Output

1 3
0 1 2
(0,0) (0,1) (0,2) (1,0)
