Go 语言打印空心星形金字塔图案程序

使用 for 循环编写一个 Go 程序来打印空心星形金字塔图案。

package main

import "fmt"

func main() {

	var i, j, k, row int

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

	fmt.Println("Hollow Pyramid 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++ {
			if k == 1 || k == i*2-1 || i == row {
				fmt.Printf("*")
			} else {
				fmt.Printf(" ")
			}
		}
		fmt.Println()
	}
}

此 Go 示例 打印给定字符的空心金字塔图案。

package main

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

func main() {

	reader := bufio.NewReader(os.Stdin)

	var i, j, k, row int

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

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

	fmt.Println("Hollow Pyramid Pattern")

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

Enter Hollow Pyramid Star Rows = 14
