Go Program to Print Hollow Diamond inside a Square Star Pattern

Write a Go program to print the hollow diamond star pattern inside a square pattern using for loop.

package main

import "fmt"

func main() {

	var i, j, k, l, row int

	fmt.Print("Enter Hollow Diamond inside a Square row = ")
	fmt.Scanln(&row)

	fmt.Println("Hollow Diamond inside a Square Star Pattern")

	for i = 1; i <= row; i++ {
		for j = i; j <= row; j++ {
			fmt.Printf("*")
		}
		for k = 1; k <= 2*i-2; k++ {
			fmt.Printf(" ")
		}
		for l = i; l <= row; l++ {
			fmt.Printf("*")
		}
		fmt.Println()
	}

	for i = 1; i <= row; i++ {
		for j = 1; j <= i; j++ {
			fmt.Printf("*")
		}
		for k = 2*i - 2; k < 2*row-2; k++ {
			fmt.Printf(" ")
		}
		for l = 1; l <= i; l++ {
			fmt.Printf("*")
		}
		fmt.Println()
	}
}

This Go example prints the hollow diamond inside a square pattern of a given character.

package main

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

func main() {

	reader := bufio.NewReader(os.Stdin)

	var i, j, k, l, row int

	fmt.Print("Enter Hollow Diamond inside a Square row = ")
	fmt.Scanln(&row)

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

	fmt.Println("Hollow Diamond inside a Square Star Pattern")

	for i = 1; i <= row; i++ {
		for j = i; j <= row; j++ {
			fmt.Printf("%c", ch)
		}
		for k = 1; k <= 2*i-2; k++ {
			fmt.Printf(" ")
		}
		for l = i; l <= row; l++ {
			fmt.Printf("%c", ch)
		}
		fmt.Println()
	}

	for i = 1; i <= row; i++ {
		for j = 1; j <= i; j++ {
			fmt.Printf("%c", ch)
		}
		for k = 2*i - 2; k < 2*row-2; k++ {
			fmt.Printf(" ")
		}
		for l = 1; l <= i; l++ {
			fmt.Printf("%c", ch)
		}
		fmt.Println()
	}
}

Enter Hollow Diamond inside a Square row = 14
Character to Print in Hollow Diamond = #
