The difference between flowchart and pseudocode is that flowchart is a diagrammatic demonstration of an algorithm, while pseudocode is an unofficial advanced level explanation of an algorithm. Flowchart diagrams are usually made use in programming to discover processes to write a program. It assists in simplifying the way things are presently working and how they could be upgraded.

It helps in discovering the major elements of a process while sketching obvious lines between the end of a process and the beginning of the next. Inspires communication between participants and creates mutual comprehending of the process, while pseudocode is not a computer language; it only depicts the algorithm of the program in normal language and arithmetic representation.

Also, there is no specific programming language to write pseudocode. In addition, it is likely to make use of pseudocodes by means of easy English language sentences.

The main difference between flowchart and pseudocode is that a flowchart shows a step by step procedure to accomplish something. In contrast, pseudocode is a notation that looks like a simple program language for program design.

A flowchart demonstrates a sequence of steps to arrive at an understandable answer. You can do just about anything with the assistance of a flowchart, as it works within the correct series of events. An example of a flowchart is when a user wants to log in to a Facebook account. Pseudocode is a casual way of notating within a program; however, it is not a computer program.

Typically, there is no particular code syntax to write pseudocode. It does not involve stringent syntax as it’s a programming language, and it uses simple English. A flowchart is an exact, almost scientific way to approach something, as it is step by step. Pseudocode is a high-level description of the working theory of a computer program.

The flowchart was the first design tool to be widely used, while pseudocode is a newer tool and has features that are more reflective of structured concepts.

Pseudocode is an informal way of writing a program; it represents the algorithm of a program in natural language and mathematical notations. A pseudocode is not a computer program. It is also possible to use pseudocode using English language statements. Unlike other regular programming, there is no syntax to follow when writing pseudocode.

A flow chart for marks calculation, the oval shape denotes the start and end, the rhombus shape denotes inputs and outputs. The diamond shape denotes the decision selection. A flowchart is written using various symbols and is also a pictorial representation of an algorithm.

Flowcharts are diagrams that use graphics to show information and data. These charts are used for people to understand the data given. It can also be used to show a step by step process to solve a particular issue. Flowcharts use boxes and arrows to show the flow of any given information. Pseudo-codes use written language.

They are used in computer programming to describe the principles of the program. Though it is used to understand programming language, it is meant for human reading and not the reading of a machine. It is popular in understanding and writing the computer programming language of Java.

Pseudocode is known to be a description of an algorithm that is already set in its high levels. The flowchart will show how the algorithm will look like in picture form. There are some people who use the flowchart when they would like to show a visual representation of the project that they are planning to work on. When the algorithm is used, this can show the step by step process on how the problem will be resolved. It can make things easier to do. Computer programmers tend to use algorithms more while operations managers may use flowchart in order to show what they would like to see.

It can be confusing to know the difference between pseudocode and a flowchart, especially if you do not realize that they are different from each other. The flowchart is the first line of visualization used by people when they want to explain the process of what they are building. This can be used for an app, or it can be used to solve a current issue that needs to be fixed soon.

Usually, after the flowchart has been created, that is the time when it would be shown to the developers who will be in charge of creating the pseudocode. The pseudocode will not be the main code yet, but it will be done based on the flowchart that has been created.

There are some people who are usually confused with the differences between a flowchart and pseudocode but the more that they understand the differences between the two, they will have no trouble differentiating and learning the differences anymore. The pseudocode is the process wherein the language (usually English) will be translated into software codes.

The flowchart, on the other hand, will show the process that needs to be followed with shapes and colors to make the data flow of the program easier to understand. The graphical representation of the use of a flowchart makes the process easy to understand even by those who are not too familiar with data programming.

A flowchart makes use of graphics in order to show data and information to people who are looking at the chart. A pseudo-code, on the other hand, makes use of a written language. Take note that any of these can be used in order to show a process. It would depend on people what they want to use.

Take note that flowchart is normally used represent the algorithm in a diagrammatic manner. The pseudocode is usually the choice of those who would like the readers to understand the programming language at the soonest possible time. The more that these are used, the more that they can be easily understood.

A flowchart is a diagrammatic description of an algorithm. Each command is placed in a box of the appropriate shape, and arrows decide the flow of the boxes. Given below are the set of boxes used for flowcharts.

Pseudocode, on the other hand, is a textual representation of an algorithm. It lists out all the logical functions an algorithm will do including the input and the output of the program.

For eg:

The program:

Sum = a +b;

Print Sum;

Pseudocode:

Input: a,b. Output-Sum

1. Enter a and b
2. a and b must be added
3. Output must be stored in Sum
4. Output must be displayed
