What is wrong -_-...?

[HTML]

This is my first attempt at making a new cpp and header file, I thought all was well before I got this funky error..can anyone help?


Practice.cpp

#include "stdafx.h"
#include <iostream>
#include <string>
#include <stdlib.h>
#include "soldier.h"
using namespace std;


#define stop system("PAUSE")
#define clear system("cls")


      int main ()
	  {
		 cout << "test";
		 stop;
		 return 0;
	  
	     
	  
	  }

solider.h

#include <iostream>
using namespace std; 

class Player
	  {
	    public:
			 
			 
			Player();
			void  Skeletonattack();
			void Skeletonxp();
			void Skeletonlvl();
			
	  private:
			  int health; int experience; int level;
	 };

solider.cpp

#include "soldier.h"
#include "stdafx.h"



			 
			  //First time with constructor..wish I had this before. >_>
			

			  //this is the dmg a skeleton takes.
			void Player::Skeletonattack()
			  {  
				  health - 2;
			  }
	        
			// The exp skeleton gives
	        void Player::Skeletonxp()
			{
				experience + 3;

			}

	        // Testing this function
			void Player::Skeletonlvl()
			{
				if (experience == 3)
					level = 1;
				cout << "You've gained a level!";
			}
	          
			//First time with constructor..wish I had this before. >_>
	          Player::Player()
			  {
				  health = 10;
				  experience = 0;
				  level = 0;
			  }
