Forum:House Cup vs. Quidditch Cup

Is the Quidditch Cup, which is awarded each year, the same item as the House Cup, which is also awarded every year? There are arguments for both saying yes and no to this question:

yes, it is the same: - in Philosophers stone, harry grieves about losing 50 points when mcgonagall finds him and says "he lost the points he earned by winning quidditch" - http://harrypotter.wikia.com/wiki/House_points says one can earn house points by winning quidditch

no, there are two different cups: - oliver wood states in prisoner of azkaban that this was his last chance of winning the cup (due to him doing his last shool year). gryffindor, however, won the (house)cup in the books before. - http://harrypotter.wikia.com/wiki/Quidditch_Cup and http://harrypotter.wikia.com/wiki/House_Cup give non consencial information about cup winners

my conclusion is that it is in fact possible to earn house points via quidditch, but that the quidditch cup of hogwarts has its own ranking, which is not influenced by anything other than quidditch. perhaps some of you can answer if this is correct
