用STARES598PCI单板开发机设计一个应用接口芯片作为四个七段LED数码管的输出口，编写一段程序，使8个LED数码管依次闪烁左移显示从输入口的逻辑开关读入的4位数字，闪烁频率为每秒一次。其外，还需实现一些附加功能，比如：可控制左移还是右移；可重新输入另外一个四位数；输入时可回显；以及输入时的十六进制到十进制的转换的等问题。 由此可见，要实现以上的功能，需要8个7段LED数码管和逻辑开关，闪烁的频率为1s。从开关读数，用LED显示。 -Machine Design STARES598PCI veneer developed with an application interface chip as the four seven-segment LED digital tube output, write a procedure so eight left blinking LED digital tube displays turn the logic of switching from the input port read 4-digit , flicker frequency of once per second. Besides, need to realize some additional features, such as: can control the left or a shift to the right can re-enter another one four-digit number input to echo and hexadecimal input to decimal conversion and other issues . Thus, to achieve the above functionality, you need eight 7-segment LED digital control and logic switches, blinking frequency of 1s. Readings from the switch, with LED display.

从C 转向C++ 对每个人来说，习惯C++需要一些时间，对于已经熟悉C 的程序员来说， 这个过程尤其令人苦恼。因为C 是C++的子集，所有的C 的技术都可以继续使 用，但很多用起来又不太合适。例如，C++程序员会认为指针的指针看起来很 古怪，他们会问：为什么不用指针的引用来代替呢？-from C to C for everyone, C habits need some time, already familiar with C programmers, this process particularly vexing. Because C is a subset of C, all the C"s technology can continue to use, but many also use up less suitable. For example, the C programmer will pointer that seemed very strange, they would ask : Why not use the pointer to replace?
