Go 语言打印空心右侧帕斯卡星形三角形程序

使用 for 循环编写一个 Go 程序来打印空心右侧帕斯卡三角形星形图案。

package main

import "fmt"

func main() {

	var i, j, row int

	fmt.Print("Enter Hollow Right Pascals Star Pattern Rows = ")
	fmt.Scanln(&row)

	fmt.Println("Hollow Right Pascals Star Triangle Pattern")

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

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

这个 Go 示例 打印给定字符的空心右侧帕斯卡三角形图案。

package main

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

func main() {

	reader := bufio.NewReader(os.Stdin)

	var i, j, row int

	fmt.Print("Enter Hollow Right Pascals Star Pattern Rows = ")
	fmt.Scanln(&row)

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

	fmt.Println("Hollow Right Pascals Star Triangle Pattern")

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

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

Enter Hollow Right Pascals Star Pattern Rows = 14
