Program/Source Code:

The source code to find the given number is palindrome or not using the for loop is given below. The given program is compiled and executed successfully.

// GoLang program to find the given number is palindrome or not
// using "for" loop.

package main

import "fmt"

func main() {
	var num int = 0
	var rev int = 0
	var rem int = 0
	var tmp int = 0

	fmt.Print("Enter Number: ")
	fmt.Scanf("%d", &num)

	tmp = num
	for num > 0 {
		rem = num % 10
		rev = rev*10 + rem
		num = num / 10
	}

	if tmp == rev {
		fmt.Printf("Given number is palindrome")
	} else {
		fmt.Printf("Given number is not palindrome")
	}
}

Output:

RUN 1:
Enter Number: 34543
Given number is palindrome

RUN 2:
Enter Number: 1235
Given number is not palindrome

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 num, rev, rem, tmp that are initialized with 0. Then we read an integer number from the user and checked the given number is palindrome or not. After that, we printed the appropriate message on the console screen.
