1) Role class CRole is the base class:

Constructor, destructor;

Member variables: avatar, HP (blood volume), ATK (attack), DEF (defense), Lv (rank), EXP (experience value);

Member function: Weapon attack, jump.

2) Hero CHero inherits from CRole class

Constructor, destructor;

The new skills of heroes, kicking (member function), hugging (member function), cause injury to each other specific values set by the students themselves;

3) Enemy class CEnemy inherits from CRole class

Constructor, destructor;

The new skills splitting (member function), tandem legs (member function) to cause injury to the other party are set by the trainees themselves;

4) Combat type CBattle

Constructors, destructors, and other member functions

The initial HP (blood) value of both sides is 100. After the start of the battle, heroes and enemies attack each other in turn. Blood loss = Attacker's skill damage + ATK (Attacker's Attack) - DEF (Defense's Defense). When one side's blood is 0, the battle ends, the player's experience value increases, and when the experience level reaches a certain level, the player's level increases.
