#1 Simple if statement in Golang Programming

Code - Golang Programming

// Program to display a number if it is positive

package main
import "fmt"

func main() {
  number := 15

  // true if number is less than 0
  if number > 0 {
    fmt.Printf("%d is a positive number\n", number)
  }

  fmt.Println("Out of the loop")
}

#2 if...else statement in Golang Programming

Code - Golang Programming

package main
import "fmt"

func main() {
  number := 10

  // checks if number is greater than 0
  if number > 0 {
    fmt.Printf("%d is a positive number\n", number)
  } else {
    fmt.Printf("%d is a negative number\n", number)
  }
}

#3 if...if else ladder statement in Golang Programming

Code - Golang Programming

// Program to relate two integers using =, > or < symbol

package main
import "fmt"

func main() {

  number1 := 12
  number2 := 20

  if number1 == number2 {
    fmt.Printf("Result: %d == %d", number1, number2)
  } else if number1 > number2 {
    fmt.Printf("Result: %d > %d", number1, number2)
  } else {
    fmt.Printf("Result: %d < %d", number1, number2)     
  }
}

#4 Nested if statement in Golang Programming

Code - Golang Programming

package main
import "fmt"

func main() {

  number1 := 12
  number2 := 20

  // outer if statement
  if number1 >= number2 {

  // inner if statement
  if number1 == number2 {
    fmt.Printf("Result: %d == %d", number1, number2)
    // inner else statement
  } else {
    fmt.Printf("Result: %d > %d", number1, number2)
  } 

  // outer else statement
  } else {
    fmt.Printf("Result: %d < %d", number1, number2)
  }
}
