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 mainimport "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")}
}
