I was on the Ubuntu Software Center and downloaded "C, C++ and Objective-C compiler(clang)." I didn't see it anywhere so i went to "search your computer and online resources" and didn't see it anywhere. I went to Ubuntu Software Center and went to the "installed" tab and searched for it. But it was not there (by the way it said that it was installed when I searched for it again except this as in the all software center in Ubuntu software center). This was weird and annoying so I went to terminal and entered
open C, C++ and Objective-C compiler but it said that it couldn't get a file descriptor referring to the console. All helpful answers will be fully appreciated.
BTW my question is not a duplicate of "How can I know what programs some apt-get package contains?" as suggested by muru as one question is asking about how can they know what a package contains where my question is asking about where my download even is, obvious difference
