Pseudo Code

A mixture of natural language and high level programming concept that describes the main ideas behind a generic implementation of a data structure or algorithm.
Algorithm  max Array (A , n)
Input : An array A storing n integers.
Output : The maximum elements in A

              CurrMax <---A[0]
                for i <-- 1 to n-1 do
                     if currMax < A[i]
                        then currMax <-- A[i]
                         return currMax

Expression: Standard mathematical symbols to describe numeric and Boolean expression.

Method Declaration : Algorithm_name (Parameter 1 , Parameter 2)

Methods : Call and returns

Programming Construction : if then[else],while loop , repeat loops for-loops , array indexing.
