代码说明:

  实现了一个用于多币种之间汇率转换的程序。用户可在左侧的下拉框中选择需要转换的两种币种,在上方输入框内输入需要转换的金额,点击“汇率转换”按钮后,下方输出框中显示转换出的对应金额并保留两位小数;点击“清空”按钮后两个文本框内容清空。且输出框内容不可修改。(A program for exchange rate conversion between multiple currencies is implemented. Users can select two currencies to be converted in the drop-down box on the left, enter the amount to be converted in the input box above, click the "exchange rate conversion" button, and display the corresponding amount in the output box below with two decimal digits retained; after clicking the "empty" button, the contents of the two text boxes are empty. And the contents of the output box can not be modified.)

    C++开发的推箱子游戏 1.类的划分 Cdraw类 绘画加载地图(包括围墙、人、箱子等等) Cman类 是否完成(过关) 即时更新地图 2.设计思想 从文件map.txt里读取地图信息,然后通过Cdraw类加载地图,通过keydown事件调用Cman里的重载函数updatemap, 单参数updateMap(UINT nChar)是用于更改当前小人以及箱子的坐标,记录下来后传给updateMap(int x1, int y1, int x2, int y2, int x3, int y3) 从而改变地图。-C development Tuixiangzi a game. Class division Cdraw painting category loaded maps (including the wall, boxes, etc.) if the class completed Cman (clearance) updated maps 2. Design ideas from the paper map.txt Lane read map information, then pass Cdraw Class Loading maps, Calling the incident through keydown Cman Lane updatemap of overloading functions, updateMap single parameter (UINT nChar) is used to change the current villains and the coordinates of the boxes, After record pass updateMap (int x1, y1 int, int x2, int y2, x3 int, int y3), thus changing map.
