> ### 循環語句 for ~~~ //支持3種形式 for init; condition; post {} for condition {} for {} ~~~ ~~~ package main import "fmt" func main() { //形式一: for number1 := 1; number1 < 3; number1++ { fmt.Printf("number1:%d\n", number1) } //形式二: number2 := 1 for number2 < 3 { fmt.Printf("number2:%d\n", number2) number2++ //不能寫成 number2 = number2++(++ 與 -- 是作為語句而不是作為表達式) } //形式三: for沒有條件將無限循環;用break 退出循環 for { fmt.Println("loop") break } } ~~~
