Golang goto Statement Example – Check palindrome number

Problem Solution:

In this program, we will read an integer number and then check the given number is palindrome or not?

Golang code to check the given number is palindrome or not using goto statement

Program/Source Code:

The source code to check the given number is palindrome or not using the goto statement is given below. The given program is compiled and executed successfully.

// Golang program to check the given number is palindrome or not
// using the goto statement

package main

import "fmt"

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

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

	temp = num
MyLbl:

	rem = num % 10
	rev = rev*10 + rem
	num = num / 10

	if num > 0 {
		goto MyLbl
	}

	if temp == rev {
		fmt.Printf("Number is palindrome")
	} else {
		fmt.Printf("Number is not palindrome")
	}
}

Output:

RUN 1:
Enter Number: 1234321
Number is palindrome

RUN 2:
Enter Number: 123432
Number is not palindrome

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 num, rev, rem, temp  that are initialized with 0 and also created a label MyLbl.

MyLbl:
        
    rem = num % 10
    rev = rev*10+rem
    num = num / 10
        
    if(num>0){
        goto MyLbl
    }
        
    if(temp==rev){
        fmt.Printf("Number is palindrome")
    }else{
            fmt.Printf("Number is not palindrome")
    }

In the above code, we checked the given number is palindrome or not by finding the reverse of a number. Here we divided the number till it becomes 0. After that, we printed the appropriate message on the console screen.
