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.
