GO BOOLEAN DATA TYPES

Boolean Data Type in Go

  • In Go, the boolean data type is declared using the bool keyword. It can hold only one of two values: true or false.
  • Default value: If a boolean variable is declared without an initial value, it defaults to false.

Example:

  • The following example demonstrates several ways to declare boolean variables:
package main
import "fmt"
func main() {
  var b1 bool = true     // Explicit type with initial value
  var b2 = true          // Implicit type with initial value
  var b3 bool            // Explicit type without initial value (defaults to false)
  b4 := true             // Short declaration with initial value
  fmt.Println(b1) // Output: true
  fmt.Println(b2) // Output: true
  fmt.Println(b3) // Output: false
  fmt.Println(b4) // Output: true
}

Note: Boolean values are commonly used in conditional expressions, which you'll explore further in the Go Conditions section.
