Golang - Boolean Data Type

In Go, the boolean data type is straightforward and useful for expressing true or false conditions. A boolean variable can only have two values: true or false. These values are commonly used in decision-making within programs.

Let's take a brief look at how boolean variables are used in Go:

package main

import "fmt"

func main() {
    var isTrue bool
    isTrue = true

    var isFalse bool
    isFalse = false

    fmt.Println("isTrue:", isTrue)
    fmt.Println("isFalse:", isFalse)

    // Example of a simple condition
    if isTrue {
        fmt.Println("This will be executed because isTrue is true.")
    } else {
        fmt.Println("This won't be executed.")
    }
}

In this example, we declare two boolean variables, isTrue and isFalse, and assign them the values true and false, respectively. The program then prints the values of these variables.

Boolean variables are commonly used in control flow structures like if statements. The example includes a basic if condition, demonstrating how a block of code is executed based on whether the boolean expression is true or false.

Boolean values are crucial in programming logic, allowing developers to create conditions and make decisions within their code. Whether it's checking if a condition is true before executing a block of code or controlling the flow of a program, boolean data types are fundamental in writing efficient and effective Go code.
