What are the differences between farce,melodrama and comedy?

Atleast ten differences please guys help me.

You need at least ten differences, but this is the basic difference
Answer
A comedy usually ends with a couple marrying or several members becoming couples and going off to say their marriage vows, but this is not the case with a farce. In a farce the humour is derived from a situation whereas in a comedy the humour is derived from a character.
