Golang goto Statement Example – Print Fibonacci series

Problem Solution:

In this program, we will create a program to generate and print the Fibonacci series on the console screen.

Program/Source Code:

The source code to print the Fibonacci series using the goto statement is given below. The given program is compiled and executed successfully.

Golang code to print Fibonacci series using goto statement

// Golang program to print Fibonacci series
// using the goto statement

package main

import "fmt"

func main() {
	var num1 int = 0
	var num2 int = 1
	var num3 int = 0
	var num4 int = 3

	fmt.Printf("%d", num1)
	fmt.Printf(" %d", num2)

Repeat:
	num3 = num1 + num2
	fmt.Printf(" %d", num3)

	num1 = num2
	num2 = num3

	num4 = num4 + 1
	if num4 <= 10 {
		goto Repeat
	}
}

Output:

0 1 1 2 3 5 8 13 21 34

Explanation:

Here, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we created four variables num1, num2, num3, num4 that are initialized with 0, 1, 0, 3 respectively and also created a label Repeat. Here, we generated and printed the Fibonacci series using the goto statement on the console screen.
