vc++将汉字转换成拼音的程序源代码，非常有意思，它不单纯转换为拼音，而且还可以设置分隔符，按规则转换：全部转换成大写、全部转换成小写、将首字母大写，还可以转换为现在流行的拼音首字母简写，也就是只取拼音首字母，按大写或小写提取，看来确实非常有意思也非常实用哦。(vc++ will be converted into Chinese characters spelling the source code, very interesting, it does not simply converted to Pinyin, but also can be set separators in accordance with the rules of conversion: the conversion of all upper case, all converted to lowercase to uppercase the first letter, but also can be converted to Pinyin is now the first letter of the popular shorthand, that is, only the first letter of alphabet, based on extraction of upper or lowercase, it seems very interesting indeed Oh also very practical.)

VC++枣子穿纽游戏源码，类似扫雷游戏的界面，不过玩法有点不一样，游戏源代码在vc++6下编译通过，你应该通过源代码能看出些玩法来。 　　相关资料：在本游戏中，你将作为一名裁缝，将尽可能多的纽扣穿成一个闭合的路线。游戏初始有 15 个纽扣，随着时间的增加，纽扣数目也增加，当达到70个时游戏即结束。只能在有纽扣的点穿线，且只能在水平方向或竖直方向穿线。线可交叉，但有纽扣的点不能交叉连接。 　　透露点秘诀：要尽可能使连线长且该连线上的纽扣数多。(VC++ source code dates to wear new game, the game interface similar to mine, but a bit different from playing the game in the source code to compile under vc++6 passed through the source code you should be able to see more options. Relevant information: in this game, you will serve as a tailor, will be wearing buttons as much as possible into a closed line. Game initial 15 buttons, an increase over time, increase the number of buttons, when the 70 hours to reach the end of the game that is. Buttons can only point in the threading, and only in the horizontal direction or vertical direction of threading. Lines cross, but the buttons can not be cross-connect point. Point revealed the secret: To the extent possible, so long and the connection to connect on a few more buttons.)
