门限算法（又名秘密共享算法）源程序，标准C实现，可直接跨平台移植。其中随机数的产生仅调用了rand()函数，建议实际使用时，修改随机数发生函数，至少前导加入srand( (unsigned)time( NULL -Threshold algorithm (also known as secret sharing algorithm) source, the standard C implementation, can be directly portable across platforms. Random number generation which only calls the rand () function, suggesting practical use, modify the random number generating function, at least preamble added srand ((unsigned) time (NULL))
