What is pseudocode?


What is pseudocode?
 
 
Pseudocode is a informal language
Pseudocode is one of the popular representation of algorithm


Pseudocode widely choose because:-

  •    Easy to read and write
  •    Allow the programmer to concentrate on the logic of the program
  •    Statements are written in simple English
  •    Each instruction is written on a separate line.
  •   Keywords and indentation are used to signify particular control structure.
  •    Each instruction is writer from top to bottom with only one entry and one  exit.
  •    END statement used to indicate the algorithm is complete
  •    This keywords should be capitalized (READ, WRITE, IF, ELSE, ENDIF, WHILE, ENDWHILE, REPEAT, UNTIL).
Example:-

        Definition:

Read name,hourly rate,hours worked,deduction rate
compute gross, deduction,net pay

        is gross>=100?
        YES: calculate deduction
        NO: no deduction

OUTPUT: - write name, gross, deduction, netpay.


ANSWER in pseudocode:-

            READ name, hourlyRate, Hoursworked.
        Grosspay= hourlyRate * hours worked
IF grossPay>=100
Deduction=grossPay * deductionRate
ELSE
Deduction=0
ENDIF
Netpay=grosspay-deduction
WRITE name,grossPay,deduction,netPay.



      ADVANTAGE OF PSEUDOCODE
  •   Can be done easily on a word processor
  •   Easily modified
  • Implements structured concepts well.

      DISADVANTAGE OF PSEUDOCODE

  • It is not visual
  • There is no accepted standard, So it varies widely from company to company
