Duplicating Knowledge in Programs

Many a times I wanted to write a Programmer's Blog. Now, I'm going to do it.

Duplicating Knowledge in Programs

I dont know how to write this ... I'm a Programmer not a writer...

If you have a knowledge in a program, put in one place. Dont replicate it.

for example -

if you have a condition check or a small piece of calc. , put in inside a function. The benefit is one access point of change. C++ dont that using Classes.

I will try to write this blog in professional way...
