Go 语言打印左箭头星形图案程序

编写一个 Go 程序，使用 for 循环打印左箭头星形图案。

package main

import "fmt"

func main() {

	var i, j, k, row int

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

	fmt.Println("Left Arrow Star Pattern")

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

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

此 Go 示例 打印给定字符的左箭头图案。

package main

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

func main() {

	reader := bufio.NewReader(os.Stdin)

	var i, j, k, row int

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

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

	fmt.Println("Left Arrow Star Pattern")

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

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

Enter Left Arrow Star Pattern row = 12
Character to Print in Left Arrow = $
