練習2:採用GUI介面設計以下程式:

1.編制一個程式,將身份證號.txt 中的資訊讀入到記憶體中;

2.按姓名字典序輸出人員資訊;

3.查詢最大年齡的人員資訊;

4.查詢最小年齡人員資訊;

5.輸入你的年齡,查詢身份證號.txt中年齡與你最近人的姓名、身份證號、年齡、性別和出生地;

6.查詢人員中是否有你的同鄉。

7.輸入身份證資訊,查詢所提供身份證號的人員資訊,要求輸入一個身份證數字時,查詢介面就顯示滿足查詢條件的查詢結果,且隨著輸入的數字的增多,查詢匹配的範圍逐漸縮小。

練習3:採用GUI介面設計以下程式

8.編寫一個計算器類,可以完成加、減、乘、除的操作

9.利用計算機類,設計一個小學生100以內數的四則運算練習程式,由計算機隨機產生10道加減乘除練習題,學生輸入答案,由程式檢查答案是否正確,每道題正確計10分,錯誤不計分,10道題測試結束後給出測試總分;

10.將程式中測試練習題及學生答題結果輸出到檔案,檔名為test.txt。
