Algorithms and flowcharts ppt (seminar presentation)..Nagendra N
The document discusses algorithms and flowcharts. It defines an algorithm as an ordered sequence of steps to solve a problem and notes they are developed during the problem solving phase of programming. Flowcharts are used to visualize the logic and flow of an algorithm by showing the individual steps and connections. Several examples are provided of writing pseudocode algorithms and drawing corresponding flowcharts to solve problems involving calculations, comparisons, and conditional logic. Decision structures like if-then-else and nested ifs are also explained.
This document discusses basic programming concepts including sequence, selection, and repetition structures. It provides examples of how to represent these concepts using flowcharts. Sequence involves executing steps sequentially. Selection determines which steps execute based on a condition. Repetition allows steps to execute repeatedly as long as a condition is met. It discusses pre-test and post-test repetition loops. The document ends with assignment problems applying these concepts.
Here is an algorithm to determine which child stole the cookie:
1. Interview each child individually
2. Ask each child if they took a cookie
3. If the child says no, go to the next child
4. If the child says yes, that child is the cookie thief
5. If all children say no, no one has confessed - the cookie thief remains unknown
This uses a sequence structure to interview each child one by one, and a selection structure (if/then) to determine if the child confesses or moving on to the next child.

Business value of business models
Requirements for software development
Requirements provide a description of what a proposed software application should do. Without detailed requirements, application development projects fail. Business models capture this detail in a way that is understandable to both the business users and the software developers. Business users do not need to understand how the system will be created; they need to understand how it will support their need. Business models are a better form of requirements for end users.

produce an ordered sequence of steps that describe
solution of problem
this sequence of steps is called an algorithm
Implementation phase
implement the program in some programming
language
3. Steps in Problem Solving
First produce a general algorithm (one can use
pseudocode)
Refine the algorithm successively to get step by
step detailed algorithm that is very close to a
computer language.
Pseudocode is an artificial and informal
language that helps programmers develop
algorithms. Pseudocode is very similar to
everyday English.
4. Pseudocode & Algorithm
Example 1: Write an algorithm to
determine a student’s final grade and
indicate whether it is passing or failing.
The final grade is calculated as the
average of four marks.
5. Pseudocode & Algorithm
Pseudocode:
Input a set of 4 marks
Calculate their average by summing and dividing
by 4
if average is below 50
Print “FAIL”
else
Print “PASS”
7. The Flowchart
(Dictionary) A schematic representation of a sequence of
operations, as in a manufacturing process or computer
program.
(Technical) A graphical representation of the sequence
of operations in an information system or program.
Information system flowcharts show how data flows from
source documents through the computer to final
distribution to users. Program flowcharts show the
sequence of instructions in a single program or
subroutine. Different symbols are used to draw each
type of flowchart.
8. The Flowchart
A Flowchart
shows logic of an algorithm
emphasizes individual steps and their
interconnections
e.g. control flow from one action to the next
10. Example
START
Step 1: Input M1,M2,M3,M4
Step 2: GRADE ← (M1+M2+M3+M4)/4
Input
M1,M2,M3,M4
Step 3: if (GRADE <50) then
Print “FAIL”
else
←
GRADE←(M1+M2+M3+M4)/4 Print “PASS”
endif
N IS Y
GRADE<50
PRINT PRINT
“PASS” “FAIL”
STOP
11. Example 2
Write an algorithm and draw a flowchart to
convert the length in feet to centimeter.
Pseudocode:
Input the length in feet (Lft)
Calculate the length in cm (Lcm) by
multiplying LFT with 30
Print length in cm (LCM)
13. Example 3
Write an algorithm and draw a flowchart that
will read the two sides of a rectangle and
calculate its area.
Pseudocode
Input the width (W) and Length (L) of a rectangle
Calculate the area (A) by multiplying L with W
Print A
14. Example 3
Algorithm START
Step 1: Input W,L Input
W, L
Step 2: A ← L x W
Step 3: Print A A←LxW
Print
A
STOP
15. Example 4
Write an algorithm and draw a flowchart that
will calculate the roots of a quadratic equation
ax + bx + c = 0
2
Hint: d = sqrt ( b 2 − 4ac ), and the roots are:
x1 = (–b + d)/2a and x2 = (–b – d)/2a
16. Example 4
Pseudocode:
Input the coefficients (a, b, c) of the
quadratic equation
Calculate d
Calculate x1
Calculate x2
Print x1 and x2
17. Example 4
START
Algorithm:
Input
Step 1: Input a, b, c a, b, c
Step 2: d ← sqrt ( b × b − 4 × a × c )
Step 3: x1 ← (–b + d) / (2 x a) d ← sqrt(b x b – 4 x a x c)
Step 4: x2 ← (–b – d) / (2 x a)
x1 ←(–b + d) / (2 x a)
Step 5: Print x1, x2
X2 ← (–b – d) / (2 x a)
Print
x1 ,x2
STOP
18. DECISION STRUCTURES
The expression A>B is a logical expression
it describes a condition we want to test
if A>B is true (if A is greater than B) we take
the action on left
print the value of A
if A>B is false (if A is not greater than B) we
take the action on right
print the value of B
20. IF–THEN–ELSE STRUCTURE
The structure is as follows
If condition then
true alternative
else
false alternative
endif
21. IF–THEN–ELSE STRUCTURE
The algorithm for the flowchart is as
follows:
If A>B then
Y N
is
print A A>B
else
print B Print A Print B
endif

largest value and prints the largest value with an
identifying message.

One of the alternatives within an IF–
THEN–ELSE statement
may involve further IF–THEN–ELSE
statement
