Go 布尔数据类型


布尔数据类型

布尔数据类型使用 bool 关键字声明,并且只能取值 truefalse

布尔数据类型的默认值为 false

示例

此示例展示了声明布尔变量的不同方法

package main
import ("fmt")

func main() {
  var b1 bool = true // 带有初始值的类型声明
  var b2 = true // 带有初始值的无类型声明
  var b3 bool // 无初始值的类型声明
  b4 := true // 带有初始值的无类型声明

  fmt.Println(b1) // 返回 true
  fmt.Println(b2) // 返回 true
  fmt.Println(b3) // 返回 false
  fmt.Println(b4) // 返回 true
}
亲自尝试 »

注意:布尔值主要用于条件测试,您将在 Go 条件语句 章节中了解更多信息。
