Presentation Transcript

Flowchart:

It is a diagram consists of symbolic block that represents the algorithm step by step

Symbols of flowchart:

- Terminal (start, stop)
- Input / output
- Processing
- Flow: concerned with direction
- Decision: for logic comparison
- Connector
- Off-page connector

Read name, mark

New_mark = mark+5

- print name, new_mark

stop

Flowchart:Ex: draw the flowchart for this algorithm:

- Begin
- startstopRead name, markprint name, new_markNew_mark = mark+5
- input name, mark
- new_mark = mark+5
- print name, new_mark
- End

studentcount =1

A

studentcount <= 10

stop

Read name, mark

new_mark = mark + 5

print name, new_mark

studentcount = studentcount +1

A

Flowchart:Ex: draw the flowchart for this algorithm:

- Begin
- studentcount =1
- if studentcount > 10 then Stop
else

- read name, mark
- calculate new_mark = mark + 5
- print name, new_mark
- studentcount = studentcount +1
- goto step 3

Read x, y, L

yes

L< 0

x2 –y + x

No

yes

L=0

2x + y

No

(x / y) + 10

Write F

stop

Flowchart:Ex:

Draw a flowchart to compute:

F = x2 –y + x L<0

2x + y L=0

(x / y) + 10 L>0

- start
- read x, y, L
- if (L<0) then
F = x2 –y + x

else

if (L=0) then

F = 2x + y

else

F = (x / y) + 10

- write F
- stop

start

yes

No

Read n

Read n

I<=n

yes

Read x

Max<x

Max = x

stop

No

Max=x

Min=x

yes

Min>x

Min = x

No

I = 2

I = I +1

Flowchart:Ex:

Trace the following flowchart to find the value of max and min variable for 4 numbers order as follows (x = 4, 2, 1, 3)?

Flowchart:

Ex:

Read name for student, when name="xxx" stop the program, if name does not equal "xxx" then compute the grade of every student. Every student has five courses. The average for the student courses has to be computed and there by the grade is given.

Avg > = 90 ------------------------> grade = 'A'

80 < =Avg < 90 ------------------------> grade = 'B'

70 < =Avg < 80 ------------------------> grade = 'C'

60 < =Avg < 70 ------------------------> grade = 'D'

Avg < 60 ------------------------> grade = 'F'

Sol:

- Start
- read name
- while (name != "xxx") do
- begin
- total = 0
- for count = 0 to 5 do
- begin
- read mark
- total = total + mark
- end

- avg = total / 5
- if ( avg >= 90) then
grade = 'A'

else

if ((avg >=80) and (avg < 90)) then

grade = 'B'

else

if ((avg >=70) and (avg < 80)) then

grade = 'C'

else

if ((avg >=60) and (avg < 70)) then

grade = 'D'

else

Grade = 'F'

- Write name, grade
- read name
- end

- stop

start

C

yes

total= 0

Count= 0

avg > = 90

Grade='A'

Read name

No

B

((avg >=80) and (avg < 90))

yes

Grade='B'

Name = "xxx"

yes

No

Read mark

stop

No

total= total + mark

((avg >=70) and (avg < 80)

yes

Grade='C'

count= count + 1

yes

No

count < 5

No

B

avg = total / 5

((avg >=60) and (avg < 70))

yes

Grade='D'

A

No

Grade='F'

Write name, grade
