Go 程序打印空心框数字图案

编写一个 Go 程序来打印 1 的空心框数字图案。在这个 Golang 空心框数字图案示例中，嵌套的 for 循环迭代行和列。if 语句（if i == 1 || i == row || j == 1 || j == col）检查是否是第一行或第一列或最后一行或最后一列。如果为真，则打印 1；否则，打印空格。

package main

import "fmt"

func main() {

    var i, j, row, col int

    fmt.Print("Enter the Hollow Box Rows and Columns = ")
    fmt.Scan(&row, &col)

    fmt.Println("Hollow Box Number Pattern")
    for i = 1; i <= row; i++ {
        for j = 1; j <= col; j++ {
            if i == 1 || i == row || j == 1 || j == col {
                fmt.Print("1 ")
            } else {
                fmt.Print("  ")
            }
        }
        fmt.Println()
    }
}

Enter the Hollow Box Rows and Columns = 7 22
Hollow Box Number Pattern
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 
1                                         1
1                                         1 
1                                         1 
1                                         1 
1                                         1 
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 

Golang 程序打印 0 的空心框数字图案

在这个空心框数字图案示例中，我们将 0 替换为 1。

package main

import "fmt"

func main() {

    var i, j, row, col int

    fmt.Print("Enter the Hollow Box of 0's Rows and Columns = ")
    fmt.Scan(&row, &col)

    fmt.Println("Hollow Box Number Pattern of 0's")
    for i = 1; i <= row; i++ {
        for j = 1; j <= col; j++ {
            if i == 1 || i == row || j == 1 || j == col {
                fmt.Print("0 ")
            } else {
                fmt.Print("  ")
            }
        }
        fmt.Println()
    }
}

Enter the Hollow Box of 0's Rows and Columns = 8 20
Hollow Box Number Pattern of 0's
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 
0                                     0 
0                                     0 
0                                     0 
0                                     0 
0                                     0 
0                                     0 
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 

此 Golang 示例允许输入数字，并以空心框图案打印该数字。

package main

import "fmt"

func main() {

    var i, j, row, col, num int

    fmt.Print("Enter the Hollow Box Rows and Columns = ")
    fmt.Scan(&row, &col)

    fmt.Print("Enter the Number to Print Hollow Box = ")
    fmt.Scanln(&num)

    fmt.Println("Hollow Box Number Pattern")
    for i = 1; i <= row; i++ {
        for j = 1; j <= col; j++ {
            if i == 1 || i == row || j == 1 || j == col {
                fmt.Printf("%d ", num)
            } else {
                fmt.Print("  ")
            }
        }
        fmt.Println()
    }
}
