Okafor Sheila Rose: Nollywood's Big-Fish Producer Anticipates Winning Awards in 2014. Read the full story here...




Okafor Sheila Rose has made her name a brand in the make believe business, though with every challenge comes a solution, Sheila has overcome the challenges of having a healthy business in Nigeria. 
"Doing business in this country is tough, we have to think outside the box and that thinking is an everyday thing. We go to locations carrying more than we should due to the way and manner communities react when they see artistes using there villages and districts as movie locations, but we have also devices ways of enticing them and getting the job done".

Many have likened her to be a fluke in the ever busy Nollywood world of fame, in this business as you would realize, some come and fade in record time, some don't even have any major job to their names, but with over a dozen blockbuster movies under her belt, its very glaring Sheila is not joking with her career. 
The Imo state born talent hunter is on top of her game and have been a brand in the field for a long time, she has done well in stamping her command on the ground with movies like .....

KEYWORDS USED IN PSEUDOCODE AND SYMBOLS USED IN DRAWING A FLOWCHART

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.capture-20120724-072322capture-20120724-072211capture-20120724-072040
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 .

Keywords

Usage

//
This represents a comment entry that is used to provide additional information about the steps in the 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.
accept
This simply accepts an input.for example to accept the number 10,the following statement can be used:
accept 10
compute
This is used to calculate the result of an expression,for example to calculate the product of two numbers:
compute product as 5 * 5
display
it is used to display an output,for example to display the number ‘25 ‘:
display 25
if…..else
This is used when,depending on on a condition,different actions may have to be taken.
repeat…..until
This is an iterative construct with a testing statement at the bottom of the iterative set of statements.
while
This is an iterative construct with a testing statement at the top of the iterative set of statements
for( ; ; )
This is an iterative construct in which a variable is initialized,incremented and an expression is tested in the same line

Guidelines For Writing Algorithms,Pseudocode And Flowcharts

Here are a few guidelines that will help you in writing an efficient algorithm:

  • An expected output should be decided by the programmer before writing an algorithm.
  • Each step in an algorithm should be written clearly,stating each task to be performed.
  • To be sure that the algorithm produces the expected output,it should be checked using sample values.
And a couple too for writing pseudocode,

  • Statements that are related should be combined to avoid writing a lengthy pseudocode. For example,
          display "Enter first number"
          accept number1
          display "Enter Second number"
          accept number2

The statements above make the for a lengthy pseudocode,it can be shortened by combining the statements. For example:
         display "Enter two numbers"
         accept number1,number2

  •  The pseudocode should be aligned properly for a clear understanding of the steps carried out.
Here are also rules recommended by the American National Standard Institute (ANSI) that are to be followed when drawing a flowchart.

  • The entire logic of a flowchart should be represented using standard symbols.
  • The flowchart should be clear,precise and easy to follow.
  • The flowchart should have only one start point and one end point.
  • The steps in a flow chart should follow top-to-bottom or left-to-right approach.
  • All necessary inputs should be listed in logical order.
  • The start and stop symbols should have only a single flow line.
  • The input,process,output and display symbols should have at least two flow line connecting to the previous symbol and to the next symbol.
  • The decision symbol should have one flow line flowing into it and two flow lines flowing out of it for each possible decision.
  • Flow charts should use page connectors if they extend over multiple pages.
  • It is useful to text the logic of the flowchart by texting the flowchart using some sample values.........
