if else 在 golang
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 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") } }
7 is odd 8 is divisible by 4 9 has 1 digit
总结 :
1 : 在 if 语句中可以进行变量的初始化
