presentation of flow chats and algorithm

2. An algorithm is a sequence of steps required to solve a
problem . It is list of well defined instruction to solve a
problems .an algorithm has the following
charecteristics-

3. 1. An algorithm ends after a fixed no of steps
2. Each step in an algorithm specifies basic operations
. These operations could include calculations input
output operations and comparisons
3. An algorithm accepts input data in a defined
format before it can be processed
4. An algorithm generates one more output after the
input is processed .
The resultant information termed as output can be
displayed or stored for future reference

4. -start
:input two numbers num1,num2
:add num 1 and num2 and assign the
result in the variable sum=num1+num2
:display sum
stop

5. -start
:declare two number A and B
:input the value of A and B
:if A>B
Print A is greater than B
Else
Print B is greater than A
STOP

8. Terminal Symbol is used to represent START
and STOP OF Flow chart .
The symbol used for terminal is oval
START or STOP

9. The symbol is used for input output is a
parallelogram .

10. The symbol used for processing is a Rectangle
.

11. Decision symbol is used to represent the
operation in which there are two alternatives
true and false .
The symbol used for decision in diamond .

12. Flow lines indicates the flow of data the arrow
symbol is used for this purpose .

13. Connector is used to join different Flow lines .
The symbol used for connector is a circle
with arrow .

14. -start
:input two numbers num1,num2
:add num 1 and num2 and assign the
result in the variable sum=num1+num2
:display sum
stop

15. start
Declare a,b sum
Sum=a+b
Print sum
stop

16. -start
:declare two number A and B
:input the value of A and B
:if A>B
Print A is greater than B
Else
Print B is greater than A
STOP

17. START
DECLARE
A , B
INPUT
A,B
IF
A
>
B
PRINT A IS
GREATER THAN B
PRINT A IS
SMALLER THAN B
STOP
