The if Statement #

Use the if statement to specify a block of Go code to be executed if a condition is true.

Syntax #

if condition {
    // code to be executed if condition is true
}

Note: if must be lowercase. Using If or IF will generate an error.

Example 1: Using values directly #

package main
import ("fmt")

func main() {
    if 20 > 18 {
        fmt.Println("20 is greater than 18")
    }
}

Example 2: Using variables #

package main
import ("fmt")

func main() {
    x := 20
    y := 18

    if x > y {
        fmt.Println("x is greater than y")
    }
}

Example explained #

In the example above, we use two variables, x and y, to test whether x is greater than y using the > operator.

Since x is 20 and y is 18, the condition evaluates to true, and the following is printed:

x is greater than y
