Go – “While Do” and “Do While” loops in go

Posted on January 6, 2023 by

Ok, so the golang language does not exactly have the word “while” in it. Anyway, the do-while and while-do loops can be easily implemented with a for loop.

Some museum socks, not exactly related to the programming language. Although they have threads, thus you can always come up with something. 🙂

The main difference between the do-while and while-do is that in the case of do-while, the loop will be executed at least one, even if the condition is already false. At while-do the iteration will not be executed, if the condition is false.

This is the example:

package main
import (
	"fmt"
)

func main() {
	fmt.Println("while do loop:")
	i := 1
	for i < 5 {
		fmt.Println(i)
		i++
	}
	fmt.Println("do while loop:")
	j := 10
	expression := true
	for ok := true; ok; ok = expression {
		fmt.Println(j)
		j++
		if j > 5 {
			expression = false
		}
	}
}

package main

import (

"fmt"

)

func main() {

fmt.Println("while do loop:")

i := 1

for i < 5 {

fmt.Println(i)

i++

}

fmt.Println("do while loop:")

j := 10

expression := true

for ok := true; ok; ok = expression {

fmt.Println(j)

j++

if j > 5 {

expression = false

}

And the result is quite expected:

while do loop:
1
2
3
4
do while loop:
10

while do loop:

do while loop:

Yup. That’s all! 🙂
