在这篇教程中,我们将通过一个简单的 Go 语言程序来学习条件判断结构的使用。以下是我们要分析的代码:
package main
import "fmt"
func main() {
if 7%2 == 0 {
fmt.Println("7 is even")
} else {
fmt.Println("7 is odd")
}
if 8%4 == 0 {
fmt.Println("8 is divisible by 4")
}
if 8%2 == 0 || 7%2 == 0 {
fmt.Println("either 8 or 7 are even")
}
if num := 9; num < 0 {
fmt.Println(num, "is negative")
} else if num < 10 {
fmt.Println(num, "has 1 digit")
} else {
fmt.Println(num, "has multiple digits")
}
}
