c 語言問題 , 希望c 高手教路

1. Open webpage with IE:
apply system call, system(char*)
system("\"C:\Program Files\\Internet Explorer\\iexplore.exe\" [url / file]");

e.g.
system("\"C:\Program Files\\Internet Explorer\\iexplore.exe\" hk.yahoo.com");

----------
2. Open webpage randomly:
generate the c string by random function, rand()
using <string> in C++ can be easier to do so.

----------
3. Delay the next call:
using Sleep(int ms) in <windows.h>

e.g.
while(true){
Sleep(rand()*100);
system(...);
}

Do you want to open the files for reading, or do you want to run (execute) them?

What are the names of the files, do you have a list residing on a disk file, or are they generated according to a known algorithm?

What are the chances that the files are not there?

What are the intervals, fixed, random?

Do you want to display the file using a browser such as IE or firefox, or do you want to open the html source file and work with the contents?
Is C a requirement, such as for homework, or any language is OK?
