golang的條件語句：
package main
import (
"fmt"
)
func main(){
age := 18
// if else if else 語句
if age == 18 {
fmt.Println("your age is 18")
}else if age > 18{
fmt.Println("your age is bigger than 18")
}else {
fmt.Println("your age is smaller than 18")
}
//swith 語句 匹配一個就退出
switch age {
case 16:
fmt.Println(your age is 16)
case 18:
fmt.Println(your age is 18)
default:
fmt.Println(your age is not 16 or 18)
}
//switch語句另一種寫法
switch {
case age < 18:
fmt.Println(your age is smaller than 18)
case age > 18:
fmt.Println(your age is bigger than 18)
default:
fmt.Println(your age is not 16 or 18)
}
// for 循環
for i :=0;i <10;i++{
fmt.Println(i)
}
// for 循環另一種寫法
i := 0
for ; i<10;i++{
fmt.Println(i)
}
//for 循環另一種寫法
i := 0
for i < 10{
fmt.Println(i)
i++
}
// for 死循環
for {
fmt.Println("1")
}
}
