入門Goプログラミング (Nathan Youngman(著)、Roger Peppé(著)、吉川 邦夫(監修, 翻訳)、翔泳社)のUNIT 4(コレクション)、LESSON 16(配列)の練習問題の解答を求めてみる。

コード

package main

import "fmt"

func printChessboard(chessboard [8][8]rune) {
 for _, row := range chessboard {
  for _, col := range row {
   fmt.Printf("%1c", col)
  }
  fmt.Println()
 }
}
func main() {
 var chessboard [8][8]rune
 chessboard[0][0] = 'r'
 chessboard[0][1] = 'n'
 chessboard[0][2] = 'b'
 chessboard[0][3] = 'q'
 chessboard[0][4] = 'k'
 chessboard[0][5] = 'b'
 chessboard[0][6] = 'n'
 chessboard[0][7] = 'r'

 for i := range chessboard[1] {
  chessboard[1][i] = 'p'
 }
 for i := range chessboard[6] {
  chessboard[6][i] = 'P'
 }

 chessboard[7][0] = 'R'
 chessboard[7][1] = 'N'
 chessboard[7][2] = 'B'
 chessboard[7][3] = 'Q'
 chessboard[7][4] = 'K'
 chessboard[7][5] = 'B'
 chessboard[7][6] = 'N'
 chessboard[7][7] = 'R'

 printChessboard(chessboard)
}
