Program/Source Code:

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

// Golang program to print Fibonacci series
// using "for" loop.

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)

	for count := 1; count <= 8; count++ {
		num3 = num1 + num2
		fmt.Printf(" %d", num3)

		num1 = num2
		num2 = num3

		num4 = num4 + 1
	}
}

Output:

0 1 1 2 3 5 8 13 21 34

Explanation:

In the above program, 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. After that we generated and printed the Fibonacci series using for loop on the console screen.
