Game menu and assigning a game to menu option

[blaxarbush911]

I have created a program that is based off the guess the number. But what ive added is a menu with four options 1 - 1 player 2 - 2 player 3 - high scores 4 - end game. Now I have the two combined at which im sure it will work but i get two erros about "unsigned int" on line 17 and function 'int main(void)' already has a body on line 51. Now i have tried every bit of trouble shooting with this making sure that everything corrisonds with each other and nothing works. So if you could please help me i would greatly appreciate it.

here is the code

#include<iostream>
#include<vector>
#include<algorithm>
#include<ctime>
#include<cstdlib>

using namespace std;

int game();
int main()
{
	int yourHealth = 100;
	int oppHealth = 100;
	int yourAttack;
	int oppAttack;

	srand(time(0));

	while(yourHealth > 0 && oppHealth > 0);
	{
		cout << "Your health: " << yourHealth << endl;
		cout << "opponent's health: " << oppHealth << endl << endl;
		system("PAUSE");
		system("CLS");
		
		yourAttack = rand() % 5 + 6;
		oppAttack = rand() % 5 + 6;

		cout << "you hit for " << yourAttack << endl;
		cout << "your opponent hit for " << oppAttack << endl;

		yourHealth -= oppAttack;
		oppHealth -= yourAttack;
		
		system("PAUSE");
		system("CLS");
	}
	if(yourHealth <= 0 && oppHealth <= 0)
		cout << "A double knockout!" << endl;
	else if(yourHealth > 0)
		cout << "you won! Congrats at winning something that took no skill you are now stupid for playing" << endl;
	else
		cout << "You Lose....and really suck at life" << endl;
	
	cout << endl;
}
int game();
int main()
{
	cout << "Menu\n\n";
	cout << "P - 1 player\n";
	cout << "PP - 2 player\n";
	cout << "H - High Scores\n";
	cout << "E - Exit\n\n";

	char choice;
	cout << "Choice: ";
	cin >> choice;

	switch (choice)
	{
	case 'p':
        case 'P':
             {	
			cout << "Your the only one\n";
			game();//call the game function

              }
			break;
	case 'pp':
        case 'PP':
 
                {	
			cout << "2 players it is.\n";

                 }
			break;
	case 'h':
        case 'H': // so lowercase h can be entered and uppercase a you can also use toupper() google it.
                
                   {	
			cout << "High scores.\n";

                    }
			break;
           
        case 'e':
        case 'E':
  
            {
             
           cout << "Exiting..." << endl;
 
            }
        break;

	default:
                 {
			cout << "You made an illegal choice.\n";
                 }
        break;
	}

	
	cin.ignore(); 
	cin.get();
}

Uhm, Do you know you have 2 main methods?

[blaxarbush911]

yes but if i take it away or modify it by adding a ; or changing it with a different name such as menu or just removing i get about 12 more erros of unsigned declorations or IntelliSense expected a declaration etc. So i have no clue how im suppose to attach the gmae

int main()
{
	int yourHealth = 100;
	int oppHealth = 100;
	int yourAttack;
	int oppAttack;

	srand(time(0));

	while(yourHealth > 0 && oppHealth > 0);
	{
		cout << "Your health: " << yourHealth << endl;
		cout << "opponent's health: " << oppHealth << endl << endl;
		system("PAUSE");
		system("CLS");
		
		yourAttack = rand() % 5 + 6;
		oppAttack = rand() % 5 + 6;

		cout << "you hit for " << yourAttack << endl;
		cout << "your opponent hit for " << oppAttack << endl;

		yourHealth -= oppAttack;
		oppHealth -= yourAttack;
		
		system("PAUSE");
		system("CLS");


	}
	if(yourHealth <= 0 && oppHealth <= 0)
		cout << "A double knockout!" << endl;
	else if(yourHealth > 0)
		cout << "you won! Congrats at winning something that took no skill you are now stupid for playing" << endl;
	else
		cout << "You Lose....and really suck at life" << endl;
	
	cout << endl;
}

to the first option in the menu
