Golang If Statement - Tutorial Kart

Golang If Statement

Go If

Golang If statement is used to conditionally execute a block of statements, based on the result of a boolean condition/expression.

In this tutorial, we will learn the syntax and usage of If statement in Go language.

Syntax

The syntax of Go If statement is

if condition { //code

}

where the condition is a boolean expression or evaluates to a boolean value. If the expression evaluates to true , the code inside the if block executes, else the code in If block is not executed.

Examples

In the following example, we will print a message based on a condition.

example.go

package main import "fmt" func main() {

var a int = 10 var b int = 20 if a < b {

fmt.Println("a is less than b") } }

Output

a is less than b

In the following program, we will use Go If Statement and check if a number given in x is even.

example.go

package main import "fmt" func main() {

var x = 14 if x%2 == 0 {

fmt.Println("x is even.") } fmt.Println("Bye.") }

Output

x is even. Bye.
