Go Program to Print Diamond Star Pattern

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

package main

import "fmt"

func main() {

	var i, j, k, row int

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

	fmt.Println("**** Diamond Star Pattern ****")

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

	for i = row - 1; i > 0; i-- {
		for j = 1; j <= row-i; j++ {
			fmt.Printf(" ")
		}
		for k = 1; k <= i*2-1; k++ {
			fmt.Printf("*")
		}
		fmt.Println()
	}
}

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

package main

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

func main() {

	reader := bufio.NewReader(os.Stdin)

	var i, j, k, row int

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

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

	fmt.Println("**** Diamond Star Pattern ****")

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

	for i = row - 1; i > 0; i-- {
		for j = 1; j <= row-i; j++ {
			fmt.Printf(" ")
		}
		for k = 1; k <= i*2-1; k++ {
			fmt.Printf("%c", ch)
		}
		fmt.Println()
	}
}
