What is Pseudo Code?- Rules, Examples, Advantages, and Disadvantages

It is advisable to plan a program before writing it on a computer so that there is no misunderstanding while writing the program. It is advisable to plan a program before writing it on a computer so that there is no misunderstanding while writing the program.

The program is planned using a variety of methodologies, including flowcharts, decision tables, and so on.

Pseudo code is a comparable approach that is used to plan the logic of the program. Pseudo codes are such instructions that the developer can use to plan the logic of a program before writing its logic.” So that it is simple to write the software.

So, this was a very easy definition of Pseudo code for you guys, but if you’re still wondering, what is Pseudo code? What are the pros and cons of developing Pseudo code and how do you write it? If you want to know everything there is to know about your Pseudo code, keep reading because we will answer all of your queries in this article.

What is Pseudo Code?

Pseudo Code is a text-based programming language that assists the developer in comprehending the algorithms of the code before writing it.

Pseudo code is an informal language that allows us to write a description of a code in our own language, such as English, Hindi, or any other language, before writing it.

Let’s look at an example to better understand Pseudo code: Below is a basic Java program that uses the code of the main () function and includes IF, ELSE statements -:

BEGIN
NUMBER s1, s2, sum
OUTPUT("Input number1:")
INPUT s1
OUTPUT("Input number2:") 
INPUT s2
sum=s1+s2
OUTPUT sum
END

This is a very basic Java software that determines if a student has passed or failed based on the number of marks he received.

In this java application, we can also collect user input for marks using a scanner, but we’ve already allocated 30 marks inside the code so that anyone who isn’t familiar with coding won’t be confused.

So, now that you’ve seen the code above, can you tell us how to write its pseudo code?

As a result, we may write the program’s pseudo code as follows:

// Program for Finding Whether Student is Pass or Failed:
IF marks is greater than 32
PRINT “Congrats, You Are Passed”
ELSE
PRINT “Sorry, You Are Failed”
IF END 

You may have gained a better knowledge of things as a result of this simple example. This should have given you a basic concept of how to write pseudo code, but now we’ll tell you how to write pseudo code from start to finish and what you should consider about.

Rules of Pseudo Code

  • Each line should contain one statement.
  • Use an indent to indicate a hierarchy.
  • Multiline structure comes to an end.
  • Initial keywords should be capitalized (READ, WRITE, IF, WHILE, UNTIL).
  • Maintain the phrasing of the assertions.

How To Write Pseudo Code?

Don’t think of writing pseudo code as a rigid guideline because it doesn’t follow a strict systematic or conventional way of being written. When writing one, however, every programmer adheres to a set of common conventions. These are the following:

  1. For reserved commands or keywords, use capital letters. For example, if you’re creating IF…ELSE statements, ensure sure IF and ELSE are in capital letters.
  2. The block body should be indented. This separates the body of each component while indenting particular sections of each block to show that those pseudocode components go in the less intended area.
  3. When drafting a statement, be explicit and utilize simple English to convey a detailed description.
  4. Each line should only contain one statement.

Different Statements’ Pseudocode

Operators :

1. Assignment Operator:

=, <- or :=

2. Comparison Operator:

== , !=, <, >, <= , and >=

3. Arithmetic Operator:

+,-, *, /, MOD(%)

4. Logical Operator:

AND, NOT and OR

5. Sum, Product:

? ?
  1. START: This is where the pseudocode begins.
  2. INPUT: Allow the user to provide input.
  3. PRINT: This command is used to print the output on the screen.
  4. READ/GET: This is the input format used when reading data from a file.
  5. INIT, SET: Set or initialize a value.
  6. INCREMENT, BUMP: Increase the variable’s value, which is similar to a++.
  7. DECREMENT: Decrease the variable’s value, which is equal to a—.
  8. DETERMINE, CALCULATE, COMPUTE: To find the outcome of the phrase.

Advantages of Pseudo Code

After reading so much about pseudo code, you may be wondering, “What are the advantages of employing pseudo code?” Or why do we utilize it in the first place? So, let’s have a look at some of its advantages:

  1. Writing pseudo code offers the programmer an excellent overview of the program even before writing it, making it easier for him to write it.
  2. Every step of Pseudo code is well-written, therefore there are fewer chances of making a mistake while writing the program.
  3. It is simple to create flowcharts, decision tables, and other diagrams once we have written the pseudo code.
  4. Pseudo code is independent of computer languages, making it simple to comprehend for programmers working in any language.
  5. Pseudo code is simple to produce, making it ideal for a beginner programmer just getting started.
  6. If a program error occurs, pseudo code can be used to determine which phase of the program is not functioning properly, which aids in the correction of the error.

Disadvantages of Pseudo Code

Although the pseudo-code is a fairly simple approach for specifying problem-solving logic, it does have the following limitations:

  • Because pseudo code has no established syntax, it is frequently written in such a way that it is not understood by others.
  • We don’t get to see any visual representation of the program because pseudo code is a text-based program design language.
  • We can’t build pseudocode because if we do, we’ll find errors in the software.
  • We can’t tell the program’s flow with the help of Pseudo code.
  • It can take a long time to write pseudo code for a complex program.
