# Algorithm and flowchart exercises

In programming, the solution to a problem is first elucidated in the form of the algorithm which contains sequential steps for the solution.

For the programmer convenience, the two forms are evolved to express the algorithm that is Flowchart and Pseudocode. A flowchart is constructed with the help of various symbols and provides more understandability to the algorithm. The algorithm and flowchart are the two sides of the same coin and dependent terms. Creating an algorithm is a very crucial step in the programming, as it decides the efficiency of the program.

Basis for comparison Algorithm Flow Chart Basic Includes sequence of steps which depicts the procedure of the solution. An information diagram made up of different shapes shows the data flow. Predefined rules are implemented. Problem-solving in terms of computers, what does it mean? We know that a computer can solve any computational problem, but how does it work? Before solving a problem one should always know what to do and how to do it, and what types of steps should be carried out etcetera.

Therefore, an algorithm is the series of steps that must be executed to solve a problem. Similarly in programming, while writing a program, an algorithm must be followed. In a simple way, a program consists of the set of instructions that generates the desired output of the given input. To make the program work properly the algorithm must be properly designed.

The design of the algorithm also ensures the effective utilization of the computing resources, for example, CPU time, RAM, etcetera. A kludgy algorithm can work well on a set of input but poorly on another set of inputs, which can also result in slowing down the system and crashing of the system. We have discussed the term algorithm in the previous definition. Now, what is a flowchart? It is nothing but a manner of representing an algorithm.

It is also known as the flow diagram, which illustrates a process or a detailed series of steps needed to produce a specific output. A flow chart is comprised of the different symbols and control lines to connect those symbols. Each symbol specifies distinct functions. It is extremely useful in programming because it simplifies the complicated algorithm and converts it into the understandable pictorial representation.

With the help of the flowchart, the application designer can easily segregate the different components of the process. It facilitates the analysation by providing the step-by-step process of the problem. An algorithm is a group of instructions that are followed in order to solve the problem.

On the other hand, the flowchart is a method of expressing an algorithm, in simple words, it is the diagrammatic representation of the algorithm. Your email address will not be published. Key Differences Between Algorithm and Flowchart An algorithm involves a combination of sequential steps to interpret the logic of the solution. In contrast, a flowchart is the pictorial illustration of the algorithm.

A flow chart is more understandable as compared to the algorithm. The algorithm is written in a language that can be perceived by humans. On the other hand, the flowchart is made up using different shapes and symbols.A flowchart is a diagrammatic representation of an algorithm.

A flowchart can be helpful for both writing programs and explaining the program to others. Note: Though flowcharts can be useful writing and analysis of a program, drawing a flowchart for complex programs can be more complicated than writing the program itself. Hence, creating flowcharts for complex programs is often ignored. Course Index Explore Programiz. Python if Statement. Python Lists. Dictionaries in Python. Popular Examples Add two numbers.

Add two numbers entered by the user.To solve this problem we will take a variable sum and set it to zero. Then we will take the two numbers 10 and 20 as input. Next we will add both the numbers and save the result in the variable sum i. Finally, we will print the value stored in the variable sum.

In this question we are asked to find the sum of 5 numbers. So, we will take two variables - sum and count and set both of them to zero. The sum variable will store the result while the count variable will keep track of how many numbers we have read.

To solve this problem we will use the concept of loop. In loop or iterative operation, we execute some steps repeatedly as long as the given condition is TRUE. In this case we will keep reading the input till we have read 5 numbers. So, we first initialize sum and count to zero. Then we will take the input and store it in a variable n. Next we will add the value stored in n to sum and save the answer in sum. Then we will increment count by 1 and check if count is less than 5. If this condition is TRUE then we will take another input.

This problem is also solved using the loop concept. We take a variable count and set it to zero. Then we print "Hello World" and increment count by 1.

Next we check if count is less than This problem can be solved in many ways so, we will encourage you to think and draw a flowchart for this problem using your imagination. To log in to facebook account we first enter the facbook URL www.

As there are many ways to solve a given problem so there are many ways to draw a flowchart. Home Sign Up Log In. Boolean Algebra.An assembly is the gathering of a large number of individuals. Such assembly is organizing to express the views, opinions and provide information on specific issues which affect the interest of a large number of people. It is organized formally by determining the subject of issues, date, place and time of assembly. In such assembly, few numbers of selected individuals give a speech on the issues and others to listen to them.

There is no interaction between the speaker and listener. It is organized to address on important organizational, political, social, economical and cultural issues. It draws the attention of the large people to the current burning problems of the society. Since, the assembly is organized on important issues, the opinions; views and information are communicated to the general people through radio, television, newspaper, etc.

Assembly of shareholders of a company, assembly of a political party, assembly of a house of representatives, constitutional assembly, etc. Types of Assembly The following are the main types of assembly:. An assembly is the gathering of large number of individuals which is organized to express the views, opinions and provide information on specific issues which affect the interest of large number of people.

A mass assembly is one in which participation is open to all. It is a very large size organization in which interested person can take participation. It is organized to make people aware of present political, social, economical and religious issues. As stated earlier, such assembly is organized formally in which few selected person speak and others listen to them. The subject of the mass assembly is of national importance due to which opinions and decisions of such assembly is equally important both to people and government.

A mass assembly takes the participation from all regions, group, sector and professions. Conference is a type of assembly which is commonly organized by political parties.

It is assembly; only selected members of the political party take active participation. It is organized to elect the leaders of the party, and constitution of the party, form policies, change policies and give direction for the smooth and efficient operation of the activities of the party.

It makes a discussion on the present political issues and systems and takes a decision. In such conference, papers and reports are presented discussed and approved by the majority of the participants. A conference is a strong means for evaluating the overall performance of a political party.

The assembly which is held once a year is called an annual general assembly. It is the assembly of shareholders.

## Difference Between Algorithm and Flowchart

All the shareholders can participate in this assembly. This is a compulsory assembly. According to Nepal Act,to call this assembly, a pre- notice of 21 days should be issued to all the shareholders. Such notice should include the information regarding date, place, time and agenda of the assembly. Further, a copy of auditor's report and board report is attached with the notice and sent to the shareholders.

These reports fully reflect about the performance and position of the company.Home Sign Up Log In. Boolean Algebra. IP Address. Logic Gates. Pseudo Code. Backtracking Algorithm. Dynamic Programming.

An algorithm is a step-by-step analysis of the process, while a flowchart explains the steps of a program in a graphical way. To write a logical step-by-step method to solve the problem is called the algorithm; in other words, an algorithm is a procedure for solving problems.

In order to solve a mathematical or computer problem, this is the first step in the process. An algorithm includes calculations, reasoning, and data processing. Algorithms can be presented by natural languages, pseudocode, and flowcharts, etc. A flowchart is the graphical or pictorial representation of an algorithm with the help of different symbols, shapes, and arrows to demonstrate a process or a program.

With algorithms, we can easily understand a program. The main purpose of using a flowchart is to analyze different methods. Several standard symbols are applied in a flowchart:. The symbols above represent different parts of a flowchart.

The process in a flowchart can be expressed through boxes and arrows with different sizes and colors. In a flowchart, we can easily highlight certain elements and the relationships between each part. If you compare a flowchart to a movie, then an algorithm is the story of that movie. In other words, an algorithm is the core of a flowchart.

Actually, in the field of computer programming, there are many differences between algorithm and flowchart regarding various aspects, such as the accuracy, the way they display, and the way people feel about them.

Below is a table illustrating the differences between them in detail. It is not surprising that algorithms are widely used in computer programming. However, it can be applied to solving mathematical problems and even in everyday life. Here comes a question: how many types of algorithms? According to Dr. As a result, he has listed 32 crucial algorithms in computer science. Despite the complexity of algorithms, we can generally divide algorithms into six fundamental types based on their function.

It refers to a way to solve problems by repeatedly breaking down the problem into sub-problems of the same kind. The classic example of using a recursive algorithm to solve problems is the Tower of Hanoi. Traditionally, the divide and conquer algorithm consists of two parts: 1.

Developed by Richard Bellman in the s, the dynamic programming algorithm is generally used for optimization problems. In this type of algorithm, past results are collected for future use. Like the divide and conquer algorithm, a dynamic programming algorithm simplifies a complex problem by breaking it down into some simple sub-problems. This is another way of solving optimization problems â€” greedy algorithm. It refers to always finding the best solution in every step instead of considering the overall optimality.

That is to say, what he has done is just at a local optimum. Due to the limitations of the greedy algorithm, it has to be noted that the key to choosing a greedy algorithm is whether to consider any consequences in the future. The brute force algorithm is a simple and straightforward solution to the problem, generally based on the description of the problem and the definition of the concept involved.There are some basic shapes and boxes included in flowcharts that are used in the structure of explaining the steps of algorithms.

Knowing how to use them while drawing flowcharts is crucial. Here are some rules that should be known:. First of all, you have to download a flowchart software. After installing a flowchart maker, you can sign up for an account and log in with your account. Flowcharts are diagrams that visually present the process of solving problems.

The steps of creating algorithms flowcharts are described below. While drawing flowcharts with Edraw flowchart makershapes can be simply dragged and dropped beside the box in any direction right, left, up or below with the help of a mouse, and they will be connected by arrows automatically.
