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.

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 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.
