Mastering Go - Second Edition

An example with multiple Go loops

This section will display multiple examples of for loops. The name of the file is loops.go and will be presented in four parts. The first code segment of loops.go is next:

package main 
 
import ( 
    "fmt" 
) 
 
func main() { 
    for i := 0; i < 100; i++ { 
        if i%20 == 0 { 
        continue 
        } 
 
        if i == 95 { 
        break 
        } 
 
        fmt.Print(i, " ") 
    } 

The preceding code shows a typical for loop, as well as the use of the continue and break keywords.

The next code segment is the following:

    fmt.Println() 
    i := 10 
    for { 
        if i < 0 { 
        break 
        } 
        fmt.Print(i, " ") 
        i-- 
    } 
    fmt.Println() 

The offered code emulates a typical while loop. Note the use of the break keyword to exit the for loop.

The third part of loops.go is next:

 i = 0 anExpression := true for ok := ...
