Go Data Types

Data type is an important concept in programming. Data type specifies the size and type of variable values.

Go is statically typed, meaning that once a variable type is defined, it can only store data of that type.

Go has three basic data types:

  • bool: represents a boolean value and is either true or false
  • Numeric: represents integer types, floating point values, and complex types
  • string: represents a string value

    • Example

    This example shows some of the different data types in Go:

    package main
    import ("fmt")

    func main() {
      var a bool = true     // Boolean
      var b int = 5         // Integer
      var c float32 = 3.14  // Floating point number
      var d string = "Hi!"  // String

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