日出日落计算,可以根据经纬度计算 日出日落时间(Sunrise and sunset calculations)

用于求三组数，每组数的各个位都不相同。第二组数为第一组的2倍，第3组数为第一组的3倍(Is used to find the number of three, the number of the bits in each group are different. The second number of groups for the first group of two times the number of the third group of three times the first group)

VC实现迷宫问题,用穷举法找出一条路径,用递归形式的算法求得迷宫中所有可能的通路,以方阵形式输出迷宫及其通路. (VC to achieve maze problems,and use brute-force method to find a path,using the recursive form of algorithm to seek all possible paths in the maze in order to form the output matrix and the path maze.)

采用c语言设计平键，校核平键的强度，实现人机交互，用户有较大的选择余地(Flat key design using c language, check the strength of flat keys, to achieve human-computer interaction, users have greater choice)

计算器，可进行四则运算，并且有符号位，退格，以及小数点。(Calculator, can be carried out in four operations, and the sign bit, backspace, and decimal point.)

说明：  自制的简单计算器。可供初级VB学者参考和分享( ............\Form1.frm ............\工程1.vbp ............\工程1.vbw)

复数类的运用输入、输出、加、减、乘、除、模长、幅角、共轭、关系(The use of complex type input, output, add, subtract, multiply, divide, die a long, pieces of angle, conjugate, relationship)

sin()函数 给定一个弧度值或者任意数值，可以计算相应的sin值即正弦值(sin () function is given a value, or any value in radians, we can calculate the corresponding value of the sine value sin)

对Excell文件进行读写操作,并可以创建excell文件(Read and Write the excell file)

VC调用java的简单例子。需要注意jvm.dll路径，路径不对就不能成功！(VC called a simple example. Attention jvm.dll path, the road would not be wrong!)
