i have hosting from Bigrock…
Understood, and your domain is presently still at GoDaddy, yes?

When I add New domain in Addon Domain Option there showing You cannot Park You Main Domain.
You do not need to park your domain at BigRock. Go ahead and add it as your Primary Domain even though (and actually, since) it will not be receiving any traffic until after you have gone to your GoDaddy account and changed its pointing to go to BigRock.
Anyone can tell me How to install my Blogger blog http://www.toptechlive.com/
anyone can tell me how to Upload file in Publice_html folder for WordPress installation…
There is more than one step there, but each step is relatively simple if you take them in order and complete each as you go.
First decide whether you want your WordPress installation in public_html (server account “root”) or a sub-folder (as “root” for the installation). Either way is fine, and either way will still allow you to only use http://www.toptechlive.com/ with nothing extra in that path to get to it. Keeping your installation in public_html (or whatever BigRock calls that) means you will not have to have an extra .htaccess file (assuming BigRock has Apache servers) to redirect your domain from public_html to its actual location in a sub-folder.
If you want to keep your installation in public_html, simply FTP-upload the wordpress.zip file into public-html, then go to File Manager at cPanel and un-zip it, then either copy or move all the files inside the /public_html/wordpress/ folder into /public_html/ (and then delete the (empty?) /wordpress/ folder).
When you get to that point, you have the option of an automatic installation or a manual installation, and I strongly suggest a manual installation to get some specific things accomplished right from the beginning.
… also without losing any links and SEO.
That should not be an issue at all. When everything is ready — there is more than I have mentioned so far — you will simply re-point your domain to its new location without ever changing its name, URL or the content of its installation.
