The difference between algorithm and flowchart is simply that algorithm is the collection of rules that should be followed while solving any particular problem. These rules are written in the form of plain text and on the other side flowchart is a diagrammatic representation of the algorithm. The flowchart demonstrates the steps as a series of boxes of different types, and the arrows connecting those boxes show the direction of data flow between the boxes. Algorithm based solutions are more complex and challenging to understand than flowchart based ones.

What is an Algorithm?
To clarify the difference between algorithm and flowchart let's understand what an actual algorithm is, so the algorithm is a method for solving a problem step by step. An algorithm is a set of guidelines for how to carry out tasks in order to produce the desired outcomes.
The algorithm must be properly designed in order for the program to function properly. Algorithm design helps in the efficient use of computing resources.
Algorithms are typically written in plain English or natural language. Among other ways, flowcharts and pseudocode can be used to represent algorithms.
Sometimes it's challenging to understand algorithms, and it can be challenging to demonstrate looping and branching by using an algorithm. Since an algorithm is a program's step-by-step process, it can be created for any problem independent of programming languages or programs.
Why do We Need an Algorithm?
How would you start if someone asked you to make a pizza and you were an amateur cook? Well, most likely you'd look up a nice pizza recipe on Google, carefully read it, collect the ingredients, and then carefully follow each step. Programmers are needed to create the codes (step-by-step instructions) for mathematical computation that tells the computer how to carry out a particular task. An algorithm is all that makes up a computer program, and different functionalities can be achieved by writing different algorithms and then implementing them in different programming languages.
Algorithm of linear search
The algorithm for searching an element e in the given array arr is given below:
Linear_Search ( Array arr, Element e)
1st step: Set x to 1
2nd step: if x > n then go to the 7th step
3rd step: if Arr[x] = e then go to 6th step
4th step : Set x to x + 1
5th step: Go to the 2nd step
6th step: Print that an element e successfully
found at index x and go to the 8th step
7th step: Print element not found
8th step: Exit

What is a Flowchart?
It is believed that making flowcharts is a straightforward process. Flow charts must follow certain standards. As a result, laws, and regulations place restrictions on flowcharts. Flow charts can be used in place of any logic that is represented using a flow diagram.
On the other side, the concepts are explained simply. To make a flow chart appear more graphical, a wide range of sizes, shapes, symbols, and boxes are used when presenting one. Debugging errors in flowcharts is a demanding and difficult task.
A flowchart is created by a programmer using a pencil and paper or by joining the shapes on the computer screen using the software. A flowchart is a crucial document for the system and each individual program in a large system because it enumerates a program's function using symbols that are simple to understand.

Main Differences Between Algorithm and Flowchart
The main difference between an algorithm and a flowchart lies in their representation and complexity. An algorithm is a textual, step-by-step approach to problem-solving, often favored by highly intelligent individuals due to its precision. In contrast, a flowchart visually represents information flow using shapes and symbols, offering a more accessible, pictorial approach. Debugging algorithmic errors is straightforward, while flowchart errors can be challenging. Algorithm creation is complex but not bound by specific rules, whereas flowcharts are rule-bound and simpler to create. Additionally, algorithms are versatile and suitable for all problem sizes, while flowcharts may struggle with larger issues.
