A summary of the experiment

Program Source code:

Summarize:

This is the first experiment in the course of the operating system tutorial to write code. To tell the truth, there have been many problems in doing this experiment, although I have already learned to write code in C language before, but because the results have not been ideal, and after the end of the study of C language after the extracurricular did not contact with C, so that before doing this experiment, I am not very familiar with C. However, after the guidance of the students and their own on-line to check the information, and ultimately it is very smooth to the DOS command program written out. In fact, in the process of compiling this program, because the wrong way to make this program into the dead loop, fortunately, by looking for problems or solve the problem, and finally perfected the program. After this experiment, I have a deep understanding of the C programming method, and I hope to understand it further and skillfully use it in future programming.
