Answer:
web crawlers or spider software
Explanation:
A search engine that crawls uses the web crawler or the spider software. And it also uses the server side JavaScript based crawlers and programming languages like Python and PHP. The search engine finds the content category through the meta keywords and directs the page to the index. The index contains details of similar types of pages, And each page has one category, and if category is not found which is rarest, a new category is being created.
Answer:
The buffer has room for 499 characters (you always have to reserve 1 for the terminating \0 character).
The code copies all characters passed in the commandline (argv[1]) into this buffer without checking. If there are more than 499 characters supplied, these will be copied into a memory location that is not intended for it. This will probably cause your program to crash, but if the extra data is somehow executed by the processor as if it were a program, this could be a way to sneak a virus into your computer.
So, while copying data, it is important to always limit the maximum amount to the allocated space.
