Go 语言打印 1 和 0 的方框数字图案程序

编写一个 Go 语言程序来打印 1 和 0 的方框数字图案。在此 Golang 方框图案示例中，嵌套的 for 循环迭代行和列。if 语句（if i == 1 || i == row || j == 1 || j == col）检查是否为第一行、第一列、最后一行或最后一列。如果为真，则打印 1；否则，打印 0。

package main

import "fmt"

func main() {

    var i, j, row, col int

    fmt.Print("Enter the Box Number Pattern Rows = ")
    fmt.Scanln(&row)

    fmt.Print("Enter the Box Number Pattern Columns = ")
    fmt.Scanln(&col)

    fmt.Println("Box Number Pattern of 1's and 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("1 ")
            } else {
                fmt.Print("0 ")
            }
        }
        fmt.Println()
    }
}

Golang 打印 0 和 1 方框数字图案的程序

在此 1 和 0 的方框数字图案示例中，我们交换了 0 和 1。

package main

import "fmt"

func main() {

    var i, j, row, col int

    fmt.Print("Enter the Box Number Pattern Rows = ")
    fmt.Scanln(&row)

    fmt.Print("Enter the Box Number Pattern Columns = ")
    fmt.Scanln(&col)

    fmt.Println("Box Number Pattern of 1's and 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("1 ")
            }
        }
        fmt.Println()
    }
}

Enter the Box Number Pattern Rows = 7
Enter the Box Number Pattern Columns = 12
Box Number Pattern of 1's and 0's
0 0 0 0 0 0 0 0 0 0 0 0 
0 1 1 1 1 1 1 1 1 1 1 0 
0 1 1 1 1 1 1 1 1 1 1 0 
0 1 1 1 1 1 1 1 1 1 1 0 
0 1 1 1 1 1 1 1 1 1 1 0 
0 1 1 1 1 1 1 1 1 1 1 0 
0 0 0 0 0 0 0 0 0 0 0 0 

此 Golang 程序允许输入方框的外部和内部值。接下来，它打印 x 作为方框的外部数字，y 作为方框的内部数字。

package main

import "fmt"

func main() {

    var i, j, row, col, x, y int

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

    fmt.Print("Enter the Outside and Inside Values = ")
    fmt.Scanln(&x, &y)

    fmt.Println("Box Number Pattern of 1's and 0's")
    for i = 1; i <= row; i++ {
        for j = 1; j <= col; j++ {
            if i == 1 || i == row || j == 1 || j == col {
                fmt.Printf("%d ", x)
            } else {
                fmt.Printf("%d ", y)
            }
        }
        fmt.Println()
    }
}

Enter the Box Number Pattern Rows and Columns = 6 20
Enter the Outside and Inside Values = 9 4
Box Number Pattern of 1's and 0's
9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 
9 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 9 
9 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 9 
9 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 9 
9 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 9 
9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9
