Exercise Solution
A.
Tick (P) the
correct alternative:
1.
It is a pictorial representation of formal instructions to perform a task :
(a) Algorithm
(b) Flowchart
(c) Program
(d) Software
2. are
used to show :
(a) Flow of instructions
(b) Input / Output
(c) Start of flowchart
(d) End
of flowchart
3. symbol is used as a :
(a) Decision box
(b) Process box
(c) Connector
(d) Output box
4.
Sometimes when a process needs to be repeated again and again it can be put in
a :
(a) Decision box
(b) Flowchart
(c) Loop
(d) Output box
B.
Write 'T’ for true and 'F' for false statement:
1. Flowcharts begin with stop. -
False
2. Flowcharts generally follows top to
bottom or left to right approach. - True
3. Connectors are used to connect two
symbols of flowchart. - False
4. Problems are broken down into smaller
steps using flowcharts. - False
p. The boxes are chosen as per user's
wish. – False
C.
Fill in the blanks:
1.
A flowchart shows the flow of task or instructions.
2. Algorithm is a set of formal instruction.
3.
The line shows the direction
in which the flowchart is flowing.
4.
Loop is used to repeat a
process again and again.
5..
If alterations are required, the flowchart may require redrawing completely.
6.
Flowcharts generally begin from top to bottom or from left to right.
D.
Answer the following questions:
1. What do you understand by Flowchart?
Ans: Flow chart is pictorial representation of
problems which are broken down into smaller steps for solving a problem and
reaching a solution.
2. Write down the limitations of using
Flowcharts.
Ans:
I.
Complex logic: For program logic is quite complicated leads
becomes complex and clumsy.
II.
Alteration and modifications: if alteration is required redesign
or re-drawing of flowchart completely.
III.
Reproduction: flowchart symbols cannot be types, reproduction of
flowcharts becomes a problem.
3. Write what each of these symbols is
used for in a flowchart?
Ans:
Home work for student. To be done by student.
