hello...m avinash..pursuing my degree in Computer Science and engineering from durgapur,West Bengal,India.I am happy to be a part of daniweb, provides me a good platform to learn and help others.
thanks to daniweb
- Interests
- apart from programing,i play flute & harmonium, i ve als interest in sketching.
- PC Specs
- C and C++. I want to learn them in very depth, but programming is not C/C++/JAVA, it is logic and algo.
