Go Program to Print Hollow Square with Diagonals Star Pattern

Write a Go program to print the hollow square star pattern with both the diagonals using for loop.

package main

import "fmt"

func main() {

	var i, j, side int

	fmt.Print("Enter Hollow Square With Diagonals Star side = ")
	fmt.Scanln(&side)

	fmt.Println("Hollow Square With Diagonals Star Pattern")

	for i = 1; i <= side; i++ {
		for j = 1; j <= side; j++ {
			if i == 1 || i == side || i == j ||
				j == 1 || j == side || j == side-i+1 {
				fmt.Printf("* ")
			} else {
				fmt.Printf("  ")
			}
		}
		fmt.Println()
	}
}

This Go example prints the hollow square with diagonals pattern of a given character.

package main

import (
	"bufio"
	"fmt"
	"os"
)

func main() {

	reader := bufio.NewReader(os.Stdin)

	var i, j, side int

	fmt.Print("Enter Hollow Square With Diagonals Star side = ")
	fmt.Scanln(&side)

	fmt.Print("Character to Print in Hollow Square With Diagonals = ")
	ch, _, _ := reader.ReadRune()

	fmt.Println("Hollow Square With Diagonals Star Pattern")

	for i = 1; i <= side; i++ {
		for j = 1; j <= side; j++ {
			if i == 1 || i == side || i == j ||
				j == 1 || j == side || j == side-i+1 {
				fmt.Printf("%c ", ch)
			} else {
				fmt.Printf("  ")
			}
		}
		fmt.Println()
	}
}
