可以进行分数的24点运算的，因为里面还额外实现了一个分数类。24点必须用VC编译，GCC编译会有问题，这个bug当时没找出来。可能是默认堆栈大小的问题。这个程序从我现在看来，写得很差。-can score 24 points in computing, because it has achieved an additional category scores. 24 points to be compiled with VC, the GCC compiler will create problems, the bug when they did not find out. May is the default stack size of the problem. This procedure seems to me now, very poorly written.
