Go Language: for loop

Go has only one looping construct : ‘for’ loop.

Syntax

for initialize: condition: updation {

         statements to evaluate

}

Example

for i := 1; i < 10; i++ {

         fmt.Println("Value of i is : " , i);

}

HelloWorld.go

package main

import "fmt"

func main() {

 for i := 1; i < 10; i++ {
  fmt.Println("Value of i is : " , i);
 }
 
}

Output

Value of i is :  1
Value of i is :  2
Value of i is :  3
Value of i is :  4
Value of i is :  5
Value of i is :  6
Value of i is :  7
Value of i is :  8
Value of i is :  9

You can omit initialize, condition and updation sections of for loop.

Below syntax is possible in Go.

for {

}

HelloWorld.go

package main

import "fmt"

func main() {

 i := 1

 for {
  fmt.Println("Value of i is : " , i)

  i++

  if i > 5 {
   break
  }
 }
 
}

Output

Value of i is :  1
Value of i is :  2
Value of i is :  3
Value of i is :  4
Value of i is :  5
