What is Pseudocode

Pseudocode is a compact and informal high-level description of a program using the conventions of a programming language, but intended more for humans.

Pseudocode is not an actual programming language. So it cannot be compiled into an executable program. It uses short terms or simple English language syntaxes to write code for programs before it is actually converted into a specific programming language.

And there is no pseudocode standard syntax and so at times it becomes slightly confusing when writing Pseudocode and so let us understand pseudo code with an example.

  • INPUT – indicates a user will be inputting something
  • OUTPUT – indicates that an output will appear on the screen
  • WHILE – a loop (iteration that has a condition at the beginning)
  • FOR – a counting loop (iteration)
  • REPEAT – UNTIL – a loop (iteration) that has a condition at the end
  • IF – THEN – ELSE – a decision (selection) in which a choice is made
  • any instructions that occur inside a selection or iteration are usually indented

 

Some Keywords That Should be Used

For looping and selection, The keywords that are to be used include Do While…EndDo; Do Until…Enddo; Case…EndCase; If…Endif; Call … with (parameters); Call; Return ….; Return; When; Always use scope terminators for loops and iteration.As verbs, use the words Generate, Compute, Process, etc. Words such as set, reset, increment, compute, calculate, add, sum, multiply, … print, display, input, output, edit, test , etc. with careful indentation tend to foster desirable pseudocode.

Do not include data declarations in your pseudocode.

Pseudocode Example 23: Perform the application that calculates the area of the triangle whose height and base length entered by the keyboard.

 

Pseudocode Example 24: The voltage (V) between the poles of a conductor is equal to the product of the current (I) passing through the conductor and the resistance (R) present on the conductor. It’s demonstrated by the V = I * R formula. What is the algorithm of the program that calculates the voltage between the poles of the conductor by using the formula according to the current and resistance values entered by the user.

 

Pseudocode Example 25: What is the algorithm that the number entered by the user from the keyboard fully divided if it is divided into 3 and 5 .

Pseudocode Examples 26: What is the algorithm that finds and shows on the screen that the water is in the form of solid, liquid or gaseous according to the temperature?

Pseudocode Examples 27: While calculating the wage of a worker at a factory, these criterias are complied;
If the worker has worked less than 40 hours, the wage is calculated by multiplying the hours worked and the hourly wage, if the employee has worked for 40 hours or more, the hours worked calculated as 2 hours. What is the algorithm that prints the amount to be paid according to this information?

 

Pseudocode Examples 28: Program to Find GCD of Two Numbers

 

Flowchart:

 

Pseudocode Examples 29: The LCM of two integers n1 and n2 is the smallest positive integer that is perfectly divisible by both n1 and n2 (without a remainder)

Flowchart

Examples 30:

If student’s grade is greater than or equal to 60

    Print “passed”

else

    Print “failed”

Examples 31:

Set total to zero

Set grade counter to one

While grade counter is less than or equal to ten

    Input the next grade
    Add the grade into the total

Set the class average to the total divided by ten

Print the class average.


Examples 32.

Initialize total to zero

Initialize counter to zero

Input the first grade

while the user has not as yet entered the sentinel

    add this grade into the running total
    add one to the grade counter
    input the next grade (possibly the sentinel)

if the counter is not equal to zero

    set the average to the total divided by the counter
    print the average

else

    print ‘no grades were entered’

Examples 33.

initialize passes to zero

initialize failures to zero

initialize student to one

while student counter is less than or equal to ten

    input the next exam result
    • if the student passed
      • add one to passes

else

    • add one to failures

add one to student counter

print the number of passes

print the number of failures

if eight or more students passed

    print “raise tuition”

 

Examples 34: Pseudocode of Bubble sort technique:

Set n to number of records to be sorted
repeat
flag = false;
for counter = 1 to n-1 do
if key[counter] > key[counter+1] then
swap the records;
set flag = true;
end if
end do
n = n-1;
until flag = false or n=1
OR the same can be expressed more concisely in words as below
repeat
set a flag to False
for each pair of keys
if the keys are in the wrong order then
swap the keys
set the flag to True
end if
next pair
until flag is not set.
