Go 语言打印空心倒星形金字塔图案程序

编写一个 Go 程序，使用 for 循环打印空心的倒星形金字塔图案。

package main

import "fmt"

func main() {

	var i, j, k, row int

	fmt.Print("Enter Hollow Inverted Pyramid Pattern Rows = ")
	fmt.Scanln(&row)

	fmt.Println("Hollow Inverted Star Pyramid Pattern")

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

此 示例 程序打印给定字符的空心倒金字塔图案。

package main

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

func main() {

	reader := bufio.NewReader(os.Stdin)

	var i, j, k, row int

	fmt.Print("Enter Hollow Inverted Pyramid Pattern Rows = ")
	fmt.Scanln(&row)

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

	fmt.Println("Hollow Inverted Pyramid Pattern")

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

Enter Hollow Inverted Pyramid Pattern Rows = 14
Character to Print in Hollow Inverted Pyramid = #
