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.
Conclusion
In this Golang Tutorial, we learned about Golang If statement, its syntax and its usage with the help of example programs.
