Example 2: Write an algorithm and draw a flowchart to find the smallest in two numbers A and B.

Algorithm: Flowchart:

Step 1: Start. Start

Step 2: Read two numbers and store them
in A and B.
Read A and B
Step 3: Compare numbers A and B. If A is
less than B, then

print "A is smallest" if Yes
A < B Print A is smallest
Else
print "B is smallest" No

Step 4: Stop.
Print B is smallest

Stop

Example 3: Write an algorithm and draw a flowchart to add first 100 natural numbers.

Algorithm: Flowchart:

Step 1: Start. Start

Step 2: Let Sum = 0 and N = 0

Step 3: N = N + 1 Sum = 0, N = 0

Step 4: Sum = Sum + N
N = N + 1
Step 5: Check If N >= 100 then
print Sum
Sum = Sum + N
Else
Is
Go to Step 3. No N >=

Step 6: Stop. 100?

Yes
Print Sum

Stop
