Go Program to Print Hollow Rectangle Star Pattern

Write a Go Program to Print Hollow Rectangle Star Pattern. In this Golang Hollow Rectangle Star pattern example, the nested for loop iterates rectangle rows and columns. The if statement (if i == 0 || i == row-1 || j == 0 || j == col-1) checks if it is a first row or last row or first column or last column. If true, print *; otherwise, print empty space.

package main

import "fmt"

func main() {

    var i, j, row, col int

    fmt.Print("Enter the Hollow Rectangle Rows = ")
    fmt.Scanln(&row)

    fmt.Print("Enter the Hollow Rectangle Columns = ")
    fmt.Scanln(&col)

    fmt.Println("Hollow Rectangle Star Pattern")
    for i = 0; i < row; i++ {
        for j = 0; j < col; j++ {
            if i == 0 || i == row-1 || j == 0 || j == col-1 {
                fmt.Print("* ")
            } else {
                fmt.Print("  ")
            }
        }
        fmt.Println()
    }
}

This Golang program allows entering the symbol and prints that symbol in a hollow rectangle pattern.

package main

import "fmt"

func main() {

    var i, j, row, col int
    var sym string

    fmt.Print("Enter the Hollow Rectangle Rows = ")
    fmt.Scanln(&row)

    fmt.Print("Enter the Hollow Rectangle Columns = ")
    fmt.Scanln(&col)

    fmt.Print("Symbol to Print Hollow Rectangle = ")
    fmt.Scanln(&sym)

    fmt.Println("Hollow Rectangle Star Pattern")
    for i = 0; i < row; i++ {
        for j = 0; j < col; j++ {
            if i == 0 || i == row-1 || j == 0 || j == col-1 {
                fmt.Printf("%s ", sym)
            } else {
                fmt.Print("  ")
            }
        }
        fmt.Println()
    }
}

Enter the Hollow Rectangle Rows = 10
Enter the Hollow Rectangle Columns = 20
