If Statement with Comparison Operators

If statements in Go evaluate boolean conditions and execute code blocks accordingly. Unlike many languages, Go does not use parentheses around conditions. The else if chain allows for multiple conditions. Comparison operators include == (equal), != (not equal), >= (greater or equal), <= (less or equal), > (greater), < (less), and logical operators && (AND), || (OR), ! (NOT).

snippet.go
go
package main
 
import "fmt"
 
func main() {
    age := 18
 
    if age >= 18 {
        fmt.Println("Access granted - you are an adult")
    } else {
        fmt.Println("Access denied - you are a minor")
    }
 
    score := 85
    if score >= 90 {
        fmt.Println("Grade: A")
    } else if score >= 80 {
        fmt.Println("Grade: B")
    } else if score >= 70 {
        fmt.Println("Grade: C")
    } else {
        fmt.Println("Grade: F")
    }
 
    name := ""
    if len(name) > 0 && name != "" {
        fmt.Println("Name provided:", name)
    } else {
        fmt.Println("No name provided")
    }
}

Breakdown

if age >= 18 { }

Simple if condition - no parentheses needed around the boolean expression

else { }

Else block executes when the if condition is false

else if score >= 80 { }

Chained else if allows testing multiple sequential conditions

&& (AND)

Logical AND operator - both conditions must be true

|| (OR)

Logical OR operator - at least one condition must be true
