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
