When drawing a flowchart,a set of symbols is used with each set of symbols representing an activity to be done.
The picture below shows various symbols and the activity they represent.
They are other symbols also used in flowchart but rarely,these are the major ones.

Every programming language has its vocabulary and syntax used when writing in that programming language,the table below shows the keywords that are used when writing a Pseudocode .

begin……end	The first statement in a pseudocode is a ‘begin’ and the last an ‘end’.The steps of the pseudocode comes between the begin….end block.
