Critique my Game

I haven't done any programming in over 10 months so this code is probably very sloppy and messy. If you have some spare time I was hoping someone could show me some ways to simplify my code. It works for the most part....

Description: A small text based battle system, made with C++

If you just want to play the game you can download it here.

Code:

---

#include <iostream>
#include <ctime>    // For time()
#include <cstdlib>  // For srand() and rand()
using namespace std;

int pHealth(20); //Player Health
int mHealth(20); //Monster Health

void win()
{
        cout << "You live to see another day.\n WIN\n";
}
void lose()
{
        cout << "You got your ass handed to you.\n LOSE\n";
}
void draw()
{
        cout << "You and the monster kill each other at the same time.\n DRAW\n";
}
void battle()
{
        int pAction, pDamage(0), pCritical, pAttack(7), pDefense(5), pDodge; //Player Values
        int mAction, mDamage(0), mCritical, mAttack(7), mDefense(5), mDodge; //Monster Values

        cout << "A monster approaches you in battle.\n";
        cout << "Your HP is: " << pHealth << "\nThe Monster's HP is: " << mHealth << "\n" ;
        cout << "What do you wish to do?\n\n1)Attack\n2)Defend\n3)Dodge\n";
        cout << "> ";
        cin >> pAction; //Get Players Action
        cout << "\n\n\n";
        srand(time(0));  // Initialize random number generator.
        mAction = (rand() % 3) + 1; //Generates random number 1 to 3

Please Feedback is Welcome :smile:

amazing, really cool man

im making something simillar in AS2.0 but ill make an interface

anyway.. really good :P

Suggestion: make the win/lose/draw functions either a macro (if your compiler supports it) or make them inline to avoid the function overhead.

Thank you for the comments...

@bone-you The reason I made them have their own functions is because if I ever expand the game it will be easier to add a exp/leveling system...
Example:

Code:

---

void win()
{
        cout << "You live to see another day.\n WIN\n";
        pExperience = mAttack + mDefense; //Just an example
}

Looks like the beginning of a nice funny game :P, nice idea :)

i think its bad programed beacuse its better if you made it using oop and global variables it would be better or u can make it using
class::inheratance if you dont want to use global variables

Classes alright, but global variables? Are you sure?
