It is commonly used as a zero-or-more wildcard character match. "o*k" matches "ok" and "oak", but not "ox".

What is a wild card for one character?
wildcard character is a special character that represents one or more other characters. The most commonly used wildcard characters are the asterisk (*), which typically represents zero or more characters in a string of characters, and the questionmark (?), which typically represents any one character. For example, in searching: run* would mean "any word that starts with 'run' and has any kind of ending." If you entered "run*" at a search engine that offered a wildcard character capability, you would get results for run, runs, running, runner, runners - in short, any possible word that might begin with the three letters. Wildcard characters are used in regular expressions (a form of programming in which input data is modified based on specified patterns) and in searching through file directories for similar file names (for example, if all the work files on a project start with the characters "P5," you could easily locate all the project files by simply searching for "P5*"). A wildcard character is a type of meta character . In various games of playing cards, a wild card is a designated card in the deck of cards (for example, the two of spades) that can be used as though it were any possible card.A question mark is used to match any single character. So:b?bwould match bib, bob, and bub, but not bulb.An asterisk matches zero or more characters. So:s*dwould match sad, said, summed, and so forth.bra*would match bra (remember zero or more), brad, branch, and so forth.
What is called robots in SEO?
Robots.txt is a text (not html) file you put on your site to tell search robots which pages you would like them not to visit. Robots.txt is by no means mandatory for search engines but generally search engines obey what they are asked not to do. It is important to clarify that robots.txt is not a way from preventing search engines from crawling your site (i.e. it is not a firewall, or a kind of password protection) and the fact that you put a robots.txt file is something like putting a note "Please, do not enter" on an unlocked door - e.g. you cannot prevent thieves from coming in but the good guys will not open to door and enter.
How do you compare items in a linked list?
You compare items in a linked list by searching for them. Iterate through the list, comparing elements with the search key. If you encounter end-of-list, then the key is not found, otherwise you have found the element desired. Note that this is a half linear search. Statistically, if an element is to be found, it will be found at the halfway point, assuming uniformly random distribution of data. In the worst case, if the element is not found, it will always take a full search to prove that. You could keep the linked list in order, by inserting each element before the element that has higher key value. This would reduce search time to half, because searching would stop with the element with higher key value. Searching is not a very efficient use of a linked-list. It would be better to use some kind of ordered list, perhaps a dynamic array with binary search, or a balanced binary tree, which has similar search performance but one with the most cost to design and implement. Linked-lists are better for keeping elements in the order they were encountered or inserted, such as processing tokens in a compiler. Sorry, but every solution has its tradeoffs.
How does a 'string' type string differ from a c-type string?
A char is a single character. A String is a collection of characters. It may be empty (zero characters), have one character, two character, or many characters - even a fairly long text.The single quote (') is used to deliniate a character during assignment:char someChar = 'a';The double quote (") is used to delineate a string during assignment:String someString = new String("hello there");Note that char is a primitive data type in Java, while String is an Object. You CANNOT directly assign a char to a String (or vice versa). There is, however, a Character object that wraps the char primitive type, and Java allows method calls to be made on the char primitive (automagically converting the char to Character before doing so).i.e. these ALL FAIL:someString = SomeChar;someString = new String(someChar);However, these WILL work:someString = Character.toString(someChar);someString = someChar.toString();Also note that a String is a static memory allocation, while a character's is dynamic. By that, I mean that when a String is created, it is allocated a memory location exactly big enough to fit the assigned string. Any change to that String forces and entirely new memory location to be allocated, the contents of the old String copied in (with the appropriate changes), and the old String object subject to garbage collection. Thus, making changes to a String object are quite inefficient (if you want that kind of behaviour, use StringBuffer instead).A character is allocated but once; all subsequent changes to a character variable simply overwrite that same memory location, so frequent changes to a character variable incur no real penalty.
