具體要求為： 使用一個(gè)二維數(shù)組記錄客車售票系統(tǒng)中的所有座位號(hào)，并在每個(gè)座位號(hào)上都顯示有票，然后用戶輸入一個(gè)坐標(biāo)位置，按Enter鍵，即可將該座位號(hào)顯示為已售。 首先我定義的輸入格式為：1,2 個(gè)人認(rèn)為主要知識(shí)點(diǎn)偽代碼如下 1.字符串分割 char[] separator = { ',' }; splitstrings = str.Split(separator); 2.字符串前后去空 str.Trim() 3.轉(zhuǎn)換類型，如果不是int類型則為false,可以處理異常情況。 int columnNum = 0;
先創(chuàng)建如下腳本，然后在Main函數(shù)中直接調(diào)用即可。 1 public class TicketingSystem 2 { 3 int[,] seatCount = new int[9, 4]; 4 5 public void CheckTicketCount() 6 { 7 bool res = true; 8 String[] splitstrings = { "row", "col"}; 9 char[] separator = { ',' }; 10 while (res) 11 { 12 Console.WriteLine("請(qǐng)輸入座位號(hào):"); 13 string str = Console.ReadLine(); 14 splitstrings = str.Split(separator); 15 if (str.Trim() == "Quit") 16 { 17 res = false; 18 Console.WriteLine("結(jié)束購(gòu)票"); 19 return; 20 } 21 22 if (splitstrings.Length < 2) 23 { 24 Console.WriteLine("輸入的格式不正確"); 25 continue; 26 } 27 string row = splitstrings[0].Trim(); 28 string column = splitstrings[1].Trim(); 29 30 int rowNum = 0; 31 bool isRow = int.TryParse(row, out rowNum); 32 if (!isRow || rowNum >= seatCount.GetLength(0)) 33 { 34 Console.WriteLine("輸入的行不正確"); 35 continue; 36 } 37 38 int columnNum = 0; 39 bool isColumn = int.TryParse(column, out columnNum); 40 if (!isColumn || columnNum >= seatCount.GetLength(1)) 41 { 42 Console.WriteLine("輸入的列不正確"); 43 continue; 44 } 45 if (seatCount[rowNum, columnNum] == 1) 46 { 47 Console.WriteLine("該座位已經(jīng)被購(gòu)買！"); 48 continue; 49 } 50 seatCount[rowNum, columnNum] = 1; 51 Console.WriteLine(rowNum + "行" + columnNum + "列車票售出"); 52 bool isEmptySeat = false; 53 for (int i = 0; i < seatCount.GetLength(0); i++) 54 { 55 for (int j = 0; j < seatCount.GetLength(1); j++) 56 { 57 if (seatCount[i, j] == 0) 58 { 59 isEmptySeat = true; 60 break; 61 } 62 } 63 if (isEmptySeat) 64 { 65 break; 66 } 67 } 68 69 if (!isEmptySeat) 70 { 71 res = false; 72 Console.WriteLine("車票售完！"); 73 return; 74 } 75 Console.WriteLine(); 76 Console.WriteLine(); 77 } 78 } 79 }
