Go for Statement

Introduction

Go for statement can repeat a list of statements multiple times. 

package main/*from   ww w  . j a v  a2  s.c o m*/

import "fmt" 

func main() { 
    i  := 1 
    for i <= 10 { 
        fmt.Println(i) 
        i = i + 1 
    } 
}

First, we create a variable called i that we use to store the number.

Then we create a for loop by using the keyword for.

Go does not have a lot of different types of loops (while, do, until, foreach, ...).

Go for loop can be used in a variety of different ways.

The previous program could also have been written like this: 

package main//  w w w  .  j  a va 2s.c om

import "fmt" 

func main() { 
    for i  := 1; i <= 10; i++ { 
        fmt.Println(i) 
    } 
}

Put if statement inside for loop. 

package main/*from ww w  .j a  v a 2s. c o m*/

import "fmt" 

func main() { 
    for i  := 1; i <= 10; i++ { 
        if i % 2 == 0 { 
            fmt.Println(i, "even") 
        } else { 
            fmt.Println(i, "odd") 
        } 
    } 
}
