golang的条件语句：
package main
import (
"fmt"
)
func main(){
age := 18
// if else if else 语句
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 语句 匹配一个就退出
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语句case可以包含多个元素，逗号隔开
switch age {
case 16，18，20，30:
fmt.Println（xxx）
default:
fmt.Println(your age is not 16 or 18)
}
//switch语句另一种写法
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)
}
// fallthrough,穿透下一个条件执行语句
switch {
case age < 18:
fmt.Println(your age is smaller than 18)
fallthrough
case age > 18:
fmt.Println(your age is bigger than 18)
default:
fmt.Println(your age is not 16 or 18)
}
执行结果:
your age is smaller than 18
your age is bigger than 18
// for 循环
for i :=0;i <10;i++{
fmt.Println(i)
}
// for 循环另一种写法
i := 0
for ; i<10;i++{
fmt.Println(i)
}
//for 循环另一种写法
i := 0
for i < 10{
fmt.Println(i)
i++
}
// for 死循环
for {
fmt.Println("1")
}
}
