Go 数据类型


Go 数据类型

数据类型是编程中一个重要的概念。数据类型指定了变量值的尺寸和类型。

Go 是静态类型的,这意味着一旦变量类型被定义,它只能存储该类型的数据。

Go 有三种基本数据类型

  • bool: 表示布尔值,要么为真 (true),要么为假 (false)
  • Numeric: 表示整数类型、浮点数和复数类型
  • string: 表示字符串值

示例

此示例展示了 Go 中一些不同的数据类型

package main
import ("fmt")

func main() {
  var a bool = true     // 布尔型
  var b int = 5         // 整型
  var c float32 = 3.14  // 浮点数
  var d string = "Hi!"  // 字符串

  fmt.Println("Boolean: ", a)
  fmt.Println("Integer: ", b)
  fmt.Println("Float:   ", c)
  fmt.Println("String:  ", d)
}
