Sorting means arrangement of elements in a defined manner(Ascending/Descending order). This is widely used in the complex algorithms to decrease the time complexity. There are six types of sorting algorithms namely, Bubble Sort, Insertion Sort, Merge Sort, Quick Sort, Heap Sort and Selection Sort.

=== Big O notation ===
 
Big O notation is a mathematical way of representing an approximate time required for an expression to complete by checking for its major dependencies.
 
For a example, f(n) = n^5 + n.
 
 
 
As we go on increasing the value of n the dependency on the second half equation on the right-hand side will reduce.
 
 
 
so, we can also say that f(n) = n^5 or complexity is O(n^5) for n equal to infinity.
 
 
 
Note: For comparison of big O complexity for different algorithms, refer following site:  http://bigocheatsheet.com/

==Searching Algorithms==
 
Information retrieval is critical in any computer application. Large sets of records are stored in computer system, from which a particular record is fetched in which required information would be stored. Each record stored in the computer environment would have a key associated to it. Based on the search criteria system scans through the records and extract the matching records only. To Increase the speed or reduce the information retrieval duration, various searching techniques are used.
 
  
Below are the basic commonly used searching algorithms.

Interview preparation requires proficient knowledge of C/C++. This article has just been recently written (July 2013) and will be elaborated soon; the articles in RED are waiting to be written. The hope is that this article will be "one-stop-shop" for most common C/C++ interview questions.
