exact definition of charge?

Charge, like mass, is an intrinsic property of matter. It comes in two types, called positive and negative, and it is measured in Coulombs.
For all the exciting details, look up any of several thousand articles on the web, or check out Wicki.

Considering it's in the physics section I presume your question relates to electric charge; Electric charge is a property mainly of electrons and protons which causes atractive and repulsive forces between them and interacts with electromagnetic fields. Electric charges are either positive or negative. If two physical bodies have like-charges (positive-positive or negative-negative) there will be a repulsive force between them. If they have opposite charges (negative-positive or positive-negative) there will be an attraction force between the two. The magnitude of the force varies inversely with the square of the distance between the two bodies. At this point we should begin looking into: electric potential, electric current, electrical energy, and electric power - but these are away from the question although very closely related.

Charge is a surface phenomena. Its definition is coulomb per unit square which is convertable into several other forms of measure.
