Go - Control flow

Control Flow - If/Else

Below is the sample code demonstrating If/Else

---

package main

import (
 "fmt"
)

func main() {
 var isBool bool
 var isBig bool = true
 fmt.Println("Value of unassigned var isBool is -->", isBool)
 fmt.Println("Value of assigned var isBig is -->", isBig)
 fmt.Println("Value of Logical AND of true && false is --> ", isBool && isBig)
 fmt.Println("Value of Logical OR of true || false is --> ", isBool || isBig)

 if toggle := false; toggle {
 fmt.Println("Value of toggle is --> ON -- True")
 } else {
 fmt.Println("Value of toggle is --> OFF -- False")
 }
}

Control Flow - For

Below is the sample code demonstrating for loop

package main

import "fmt"

func main() {
	x := 0
	y := 0
	var xbreak int = 3
	for {
		if x++; x > xbreak {
			fmt.Println("Value of x at break after it is increased more than 3 -->", x)
			break
		}
		fmt.Println("The moment value of x --> ", x)
	}

	fmt.Println("\n")

	for y < 3 {
		fmt.Println("Value of Y after incrementing it and as long as it is less than 3 -->", y)
		y++
	}

	fmt.Println("\n")

	for z := 0; z < 10; z++ {
		if z < 8 {
			continue
		}
		fmt.Println("Value of z is as long as it is lt 10 is --> ", z)
	}

}

Control Flow - Switch

Below is the sample code demonstrating switch

---

    
package main

import "fmt"

func main() {
	switch signal := 2; signal {
	case 0: //here the signal value is evaluated for 0
		fmt.Println("Red as the value of Signal is --> ", signal)
	case 1: //here the signal value is evaluated for 1
		fmt.Println("Green as the value of Signal is --> ", signal)
	case 2: //here the signal value is evaluated for 2
		fmt.Println("Orange as the value of Signal is --> ", signal)
	}

	var score int = 100
	switch {
	case score < 50:
		fmt.Println("Beginner")
	case score > 50 && score <= 75:
		fmt.Println("Advanced")
	default:
		fmt.Println("Expert")
	}
}
