Thapar University

Yes, you can. It doesn't matter. In college, they will teach you programming from basics. So no need to worry, but yes, you have to do lot of hard work.

They can provide you with accommodation if rooms will be available in guest house. I have no idea whether they have guest house or not.

Please use college predictor tool for better results
