Avoiding multiple objects of same name in C++

I am building a simple package manager for my new Linux distro (check it out as soon as I finish) and have run into a problem. My install() and remove() functions need to access an unspecified amount of Package objects. This is the install function.

void install(int argc, char *argv[]) throw()
{
        for (int i = 2; i <= argc; i++)
        {
                Package p(argv[i]);
                p.fetch();
                cout << "Package " << p.getRef() << " retrieved succesfully from server.\n";
                p.install();
                cout << "Package " << p.getRef() << " installed succesfully.\n";
        }
}

I suspect this code isn't entirely kosher; this would result in several objects named p which would probably cause a compilation and/or runtime error. What I'm looking for is either a way to change the name p in each iteration of the loop or delete p after one iteration so I will be free to create another object of that name.

There is no discernible problem with your code nor will there be any issue with multiple objects. The variable p has automatic storage duration and is destroyed when it goes out of scope. When this means is that at the end of each iteration of the for loop p is destroyed and no longer exists.
