编写一个函数，要求输入年月日时分秒， 输出该年月日时分秒的下一秒。 如输入2011年12月31日23时59分59秒， 则输出2012年1月1日0时0分0秒。 需要考虑闰年 和 2月的特殊情况 (Write a function that requires input date, hour, minute and second outputs of the date when the next second. If the input at 23:59:59 on December 31st, 2011, output at 0:00:00 on January 1, 2012. Leap year and February need to consider the special case)

用C++编写的科学计算器,功能比较齐全实用。(Written in C++ scientific calculator, function more complete and practical.)

VB版高级功能计算器，除了具有数学运算外，还包括三角函数、反三角函数、双曲三角函数、绝对值等运算，还可以进行一些比较复杂的表达式计算。它还有函数绘图、数据统计和自定义常数等功能。(VB version of the advanced features calculators, arithmetic addition, but also includes trigonometric functions,反三角函数, hyperbolic trigonometric functions, such as computing the absolute value can also be used for the expression of some of the more complex calculation. It also has function mapping, data and custom features such as constant.)

一个小网页浏览器，很好用的，如果可以讨论一下也行(A small web browser, the good, if you can talk about is also OK)

此系统由VC++ 6 0 MFC开发而成,主要实现一些基本的界面操作,如画笔画刷,文字改变字体颜色,以及时钟显示和小型购物系(This system is developed by VC 60 MFC. It mainly implements some basic interface operation, such as brush, text changing font color, clock display and small shopping department.)

这是用VB写的数控G代码读取，编译，并显示。给做数控系统的朋友做参考。(It is written in VB CNC G-code read, compile, and displayed. CNC system to make a friend for reference.)

用于将txt格式数据，转换为.dat格式的数据，便于CASS处理。(Txt format for the data is converted to. Dat format, easy CASS processing.)

表达式求值程序，很好的实现表达式的ascii码输入，到数值计算(Expression evaluation procedures, to achieve a very good expression of the ascii code input to the numerical calculation)

属于C++里继承与派生类的小程序，主要是多层派生里的指针继承问题，仅供参考(Belonging C++ inheritance and derived classes in a small program, mainly derived pointers in multilayer succession for reference purposes only)

说明：  简单计算器.热爱C++,但还是学生，故来此向大家学习。谢谢。(simple calculator)
