[lug] Doubt in reading source

[MANIGANDAN V]

hi,
I have installed srpm(source rpm).I dont know where the source code is installed.when i use find it is simply saying the file name and a colon but not the path.
Where are the sources of different programs present inside the linuxbox.Is there any general convention or path in which all the source code exist.
If i have to get it on net which site is better.
KINDLY MAIL ME 	IN DETAIL SO THAT LET ME ALSO ENJOY THE POWERS OF OPENSOURCE LINUX	
With regards
