What is programming
As this course is titled “Introduction to programming”, therefore it is most essential and appropriate to understand what programming really means. Let us first see a widely known definition of programming.
Definition: "A program is a precise sequence of steps to solve a particular problem.” It means that when we say that we have a program, it actually mean that we know about a complete set activities to be performed in a particular order. The purpose of these
activities is to solve a given problem.
Alan Perlis, a professor at Yale University, says:
"It goes against the grain of modern education to teach children to program. What fun is
there in making plans, acquiring discipline in organizing thoughts, devoting attention to
detail and learning to be self-critical? "
It is a sarcastic statement about modern education, and it means that the modern
education is not developing critical skills like planning, organizing and paying attention
to detail. Practically, in our day to day lives we are constantly planning, organizing and
paying attention to fine details (if we want our plans to succeed). And it is also fun to do
these activities. For example, for a picnic trip we plan where to go, what to wear, what to
take for lunch, organize travel details and have a good time while doing so.
When we talk about computer programming then as Mr. Steve Summit puts it
“At its most basic level, programming a computer simply means telling it what to do, and
this vapid-sounding definition is not even a joke. There are no other truly fundamental
aspects of computer programming; everything else we talk about will simply be the
details of a particular, usually artificial, mechanism for telling a computer what to do.
Sometimes these mechanisms are chosen because they have been found to be convenient
for programmers (people) to use; other times they have been chosen because they're easy
for the computer to understand. The first hard thing about programming is to learn,
become comfortable with, and accept these artificial mechanisms, whether they make
``sense'' to you or not. “
