Introduction to Computer Program
Before getting into computer programming, let us
first understand computer
programs and what they do.
A computer program is a sequence of instructions written using a Computer
Programming Language to perform a specified task by the computer
.
The
two important terms
that
we
have used in the above definition
are
:
Sequence of instructions
Computer Programming Language
To understand these terms, consider a situation when someone asks you about how
to go to
a nearby KFC. What exactly do you do to tell him the way to go to KFC?
You will use Human Language to tell the way to go to KFC
,
something as follows:
First go straight, after half kilometer, take left from the red light and
then drive around one kilometer
and you will find KFC at the right.
Here, you have used English Language to give several steps to be taken to reach
KFC. If they
are
followed in the following sequence, then you will reach KFC:
1.
Go
straight
2.
Drive
half kilometer
3.
Take
left
4.
Drive
around one kilometer
5.
Search
for
KFC at your right side
Now, try to map the situation with
a
computer program.
The
a
bove sequence of
instructions is actually a
Human Program
written in
English Language
, which
instructs on how to reach
KFC f
rom a given starting point. This same sequence could
have been given in Spanish
, Hindi
, Arabic
,
or any other human language
,
provided
the person seeking direction
knows
any of these
languag
es.
