Prepare a flow chart
and algorithm for simple
problem

11. Algorithm and flowchart Definition
• Writing 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, pseudo code and
flowchart 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

12. Symbols Used In Flowchart
Symbol Purpose Description
Flow line Indicates the flow of logic
by connecting symbols.
Terminal(Stop/Start) Represents the start and
the end of a flowchart.
Input/Output Used for input and output
operation.
Processing Used for arithmetic
operations and data-
manipulations.
Decision Used for decision making
between two or more
alternatives.

13. Algorithm and flowchart
Example 1: Find the Sum of
Two Numbers Entered
Step 1: Read the Integer n1.
Step 2: Read Integer n2.
Step 3: Perform the addition by
using the formula:
sum= n1+ n2.
Step 4: Print the Integer sum.

14. Algorithm and flowchart
Example 2: Convert
Temperature from Fahrenheit
(°F) to Celsius (°C)
Step 1: Read temperature in
Fahrenheit,
Step 2: Calculate temperature
with formula C=5/9*(F-32),
Step 3: Print C.

15. Algorithm and flowchart
Example 3: Determining the
Largest Number
Step 1: Read the Integer A.
Step 2: Read Integer B.
Step 3: If B is greater than A,
then print B, else A.

16. flowchart Find the largest among three different
numbers entered by the user.
