C Problem _c

After entering the university, the high school contacts of C forget almost. There are many languages in college. Maybe he is the one who is accustomed to it. Even programming is mixed. Except for Java. C/c++ms not been divided. Especially with the dev-c++ compiler. In the ACM a year is just mixed up. No way. Who let this compiler specify C + +. But can do C (who make C + + compatible C?). As a result, I don't know how to mix. It's only now that. oneself to C.. I know a little bit of grammar (the severity of the grammar is forgotten). Now I have a Linux class. Mr Yang had to get us back to C before we knew we were on C. Too short for the other stuff (is it really too long?) next time, get your hair cut. hehe), the dean of the Department (Mr Yang) let us use pure C to achieve a copy of a file or directory (the class has a sweat. Also said to reduce our requirements, do not implement directory nesting (that Dongdong will certainly use recursion), the next time to fix. or shell script. To the script. We're basically not going to say that. After the physical test today, I did it. The general result is coming out. But there are still problems. Copying files and directories is no problem. But it had a tail in the copy file (two more letters added). Headache ... It should be in the copy (that is, there is a problem with the read and write file). But I didn't think it through. Now put the code to post it. To master answer: Code://Now if there are only two parameters.
