FP-growth算法的改进C++程序,具有较好的扩展性和应用性,本程序改成用行读取，然后在内存中解析。更有效的方式是采用块读取方式（本人在以前项目中验证过，速度大为提高。）(FP-growth algorithm C++ Procedures, have good scalability and application, the procedure changed to use line to read, and then resolve in memory. More effective approach is the use of block-read mode (I tested before the project, speed greatly improved.))
