Go Program to Print X Star Pattern

Write a Go program to print the X star pattern using for loop. 

package main

import "fmt"

func main() {

	var i, j, num, row int

	fmt.Print("Enter X Star Pattern row = ")
	fmt.Scanln(&row)

	fmt.Println("X Star Pattern")

	num = row*2 - 1

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

This Go example prints the X pattern of a given character.

package main

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

func main() {

	reader := bufio.NewReader(os.Stdin)

	var i, j, num, row int

	fmt.Print("Enter X Star Pattern row = ")
	fmt.Scanln(&row)

	fmt.Print("Character to Print in X Pattern = ")
	ch, _, _ := reader.ReadRune()

	fmt.Println("X Star Pattern")

	num = row*2 - 1

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

Enter X Star Pattern row = 10
Character to Print in X Pattern = $
