CHAPTER TWO
Algorithms and Flowcharts
Introduction
A program is a set of instruction gave to the computer to execute
successive operations leads to solve specific problem. In general to
solve any problem in computer we must follow these steps:
1. Analyze the problem.
2. Write an Algorithm.
3. Draw flowchart.
4. Convert the flowchart to program.
5. Run the program and test the solution.

1-1: Algorithms
It is a combination of phrases and events that can be arranged as steps
to solve a specific problem. That can be done by understanding this
problem whether it mathematic or logic before convert it to flow chart.
As example when we borrow some books from the library, the remaining
books number (NR) is the subtraction of the borrowed books number (NB)
from the original number (NO). To write the algorithm for this simple
problem we will follow these steps:
Input the number of books in the library (NO).
Input the number of borrowed books (NB).
Find the remaining books number (NR), NR = NO-NB
Print NR

1-2: Flowcharts
Flowcharts are graphs that represent the
formal view used to solve any problem.
Flowcharts help the programmer to write his
program. Flowcharts consist of a shapes
connected by a straight lines. The following
table shows these shapes and their operations.

We can summarize the use of algorithms and flowcharts as
follow:
1. To show the mathematical logic used to solve problems.
2. To show how the data processing is done.
3. Helps the programmer to write his program.
4. Divides the big problem to smaller parts.
5. To avoid the errors that occurred during writing the
program.
6. It is a middle step between problem difficulty and its
conversion to suitable program.
7. Easy to convert it to any programming language.

In general, we can divide flowcharts to a four
shapes (charts):
1. Simple sequence charts
2. Branched charts.
3. Single loop charts.
4. Multi-loop charts.

1-2-1: Simple sequence charts
The events arrangement of this type is as straight sequence from the beginning of
the program to the end (Event-1 to Event-n in figure below). This type of charts does
not have any branches or loops.

The document discusses algorithms and flowcharts. It defines an algorithm as a sequence of steps to solve a problem and notes they can be expressed in various notations like pseudocode and programming languages. It then defines a flowchart as a diagram that represents an algorithm using symbolic shapes and describes the common shapes used in flowcharts like rectangles, diamonds, and arrows. Examples of flowcharts that compute sums and averages are provided.

The document discusses the program development cycle, including problem statements, algorithms, flowcharts, and their purposes. It provides examples of algorithms to find the largest of three numbers and the sum of the first five natural numbers. Flowcharts graphically represent algorithms using standard symbols like rectangles, diamonds, and arrows. While flowcharts help with communication, analysis, and documentation, they can be time-consuming for complex logic and difficult to modify.

Here are the algorithms and flowcharts for the exercises: 1. Algorithm: Step 1: Input number 1 (N1) Step 2: Input number 2 (N2) Step 3: If N1 > N2 then print N1 else print N2 Flowchart: Start → Input N1 → Input N2 → N1 > N2? → Yes → Print N1 → No → Print N2 → Stop 2. Algorithm: Step 1: Input radius (R) of circle Step 2: Calculate area (A) as π * R^2 Step 3: Print the area (A) Flowchart: Start → Input R → A =

Problem solving methodologyProf. Dr. K. Adisesha

Introduction The term problem solving is used in many disciplines, sometimes with different perspectives and often with different terminologies. The problem-solving process starts with the problem specification and end with a correct program. The steps to follow in the problem-solving process are:  Problem definition  Problem Analysis  Algorithm development  Coding  Testing & Debugging  Documentation & Maintenance The stages of analysis, design, programming, implementation and maintenance form the life cycle of the system.

This document outlines an assignment to analyze and design a program for sequential control flow. The objectives are to understand computational problem solving, sequential logic, and how to create IPO charts, algorithms, and flow charts. As an example, students are instructed to create these analysis tools to solve a temperature conversion problem that takes Celsius input and outputs Fahrenheit and Kelvin scales using defined formulas. The document provides background on problem solving techniques, sequential control flow, and common analysis tools like IPO charts, algorithms using pseudocode, and flow charts using standard symbols.

Algorithm for computational problematic sitSaurabh846965

A computer requires precise instructions from a user in order to perform tasks correctly. It has no inherent intelligence or ability to solve problems on its own. For a computer to solve a problem, a programmer must break the problem down into a series of simple steps and write program code that provides those step-by-step instructions in a language the computer can understand. This process involves understanding the problem, analyzing it, developing a solution algorithm, and coding the algorithm so the computer can execute it. Flowcharts can help visualize algorithms and problem-solving logic in a graphical format before writing program code.

This document outlines the grading structure, textbooks, and key concepts for an applied programming course in Python. It discusses the following main points: - Grading is based on quizzes, assignments, a project, class participation, midterm, and final exam. - The programming process involves 5 main steps: defining the problem, planning the solution, coding, testing, and documenting. Common planning tools include top-down design, algorithms, and flowcharts. - Programming constructs allow for sequential, conditional, and repetitive control structures to structure program logic and flow. These include if/else statements, loops, and functions.

Algorithm and flowchart2010Jordan Delacruz

An algorithm is a step-by-step process for solving a problem or completing a task. There are two main tools used to document algorithms: flowcharts and pseudocode. A flowchart is a graphical representation of an algorithm that uses standardized symbols to show the sequence of steps, while pseudocode specifies the algorithm steps using natural language. The five steps in using a computer as a problem-solving tool are: developing an algorithm and flowchart, writing the program code, entering the program into the computer, testing and debugging the program, and running the program to obtain results.

The role of wall art in interior designingmeghaark2110

Wall art and wall patterns are not merely decorative elements, but powerful tools in shaping the identity, mood, and functionality of interior spaces. They serve as visual expressions of personality, culture, and creativity, transforming blank and lifeless walls into vibrant storytelling surfaces. Wall art, whether abstract, realistic, or symbolic, adds emotional depth and aesthetic richness to a room, while wall patterns contribute to structure, rhythm, and continuity in design. Together, they enhance the visual experience, making spaces feel more complete, welcoming, and engaging. In modern interior design, the thoughtful integration of wall art and patterns plays a crucial role in creating environments that are not only beautiful but also meaningful and memorable. As lifestyles evolve, so too does the art of wall decor—encouraging innovation, sustainability, and personalized expression within our living and working spaces.
