The if Statement in Go
- The if statement is used to run a block of code only when a specified condition is true.
if condition {
// code to execute if condition is true
}
Note: The keyword if must be written in lowercase. Writing it as If or IF will cause a syntax error.
Example:
- In this example, we check whether 20 is greater than 18. Since the condition is true, the message is printed:
package main
import "fmt"
func main() {
if 20 > 18 {
fmt.Println("20 is greater than 18")
}
}
Output:
20 is greater than 18
Example2:
package main
import "fmt"
func main() {
num1 := 20
num2 := 18
if num1 > num2 {
fmt.Println("num1 is greater than num2")
}
}
