標籤進行之內四則運算简体版

原文原文鏈接

1.需求分析

　　環境:C#窗體應用程序.git

　　功能需求:github

　　　　響應:　　　　字母鍵1234選擇加減乘除,　　enter鍵結束程序顯示統計結果.dom

　　　　輸入數據:　　隨機1~10整數,　　接收整數答案.
測試

　　　　輸出數據:　　運算結果,　　判斷對錯,　統計答對答錯數量.spa

2.具體設計思路

　　Form1(運算窗體)設計

　　　　產生1~10的random整數並在兩個文本框中顯示3d

　　　　字母鍵qwer對應運算符＋－×÷code

　　　　判斷用戶輸入的結果是否正確,right++||wrong++orm

　　按下結束(enter)後調用Form2.blog

　　Form2(統計結果)

　　　　顯示答對的數量&顯示答錯的數量

3.代碼實現
