Go 程序打印左侧帕斯卡星形三角形

使用 for 循环编写一个 Go 程序来打印左侧帕斯卡星形三角形。 

package main

import "fmt"

func main() {

	var i, j, k, row int

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

	fmt.Println("Left Pascals Star Triangle Pattern")

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

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

此 Go 示例 打印给定字符的左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, k, row int

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

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

	fmt.Println("Left Pascals Star Triangle Pattern")

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

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

Enter Left Pascals Star Pattern Rows = 12
