前往打印空心直角三角星图案的程序

编写一个Go程序，使用for循环打印空心直角三角形星形图案。

package main

input "fmt"

func main() {

var i, j, row int

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

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

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

这个Go例子打印了一个给定字符的空心直角三角形图案。

package main

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

func main() {

reader := bufio.NewReader(os.Stdin)

var i, j, row int

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

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

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

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

Enter Hollow Right Triangle Star Rows = 15
Character to Print in Hollow Right Triangle = #
