Concepts / ধারণা

What is Concept ?  

Concept is idea or output of thinking to make a work more easily or do some thing different . Some time a good concept can change our life our status even every thing . But always a good concept have no need some thing critical . Concepts can make a easy thing to a interesting and impotent thing . Actually if we think about some thing and try  to find out different way to use of that think than we may get a lot's of idea/concept .
I like to think with every thing from a ant to space .Think about every thing every thing . Try to be Creative  and do something for the world for the well fare of future generation . It's time to do some thing .

Library Management System In code C Programming Language

Library management system in C programming language.This project was made by me and one of my friend at the early time of our Computer Science study.So programs are written very easily to understand to any beginner . without (graphical user interface) GUI .
You can see the output of this program form this link : See Video

You can download the code for study from hare :    Download
