I'm creating a hangman game and I need help as to where I need the players to have an option of seven guesses before game is over can you please help

#include <iostream>
#include <cmath>
#include <iomanip>
#include <stdio.h>

using namespace std;

void oneplayer()
{
cout << "hello";
}

void twoplayer(int &n, int position[5])
{
char letter='a';
int cap,i;
n=1;
cap = 12;
for(i=0;i<=cap;i++)
{
cin >> letter;
letter = toupper(letter);
if (letter != '.')
{
position[i]=letter;
n++;
}
else
i = cap;
}





}

/*void letterFreq(int freq[])
{
char letter;
//this while loop allows the user to enter characters and it distinguishes them
//individually increasing the value assigned to that letter in the freq array
while (letter != '.')
{
letter = getchar();
letter=toupper(letter);
freq[letter]++;
}
}*/

void twoplayerIO()
{
cout << "\nPlayer 1 please enter a word without player 2 watching";
char guess;
int position[91];
int i, n,wrongGuess;
wrongGuess=0;
char letter,sentence;
//this part goes throught the alphabet because 'A' starts at value of 65
for (i=65; i<91; i++)
position[i] = 0;
cout << "\nType in your word and enter a period when done.\n";
//this below calls up to the function where the word is recieved
twoplayer(n,&position[letter]);
for (i = 0; i < n-1; i++)
if (position[i]!=0)
cout << position[i] << " ";

cout << "\n\nits your turn player 2\n"
<< "enter your first guess.\n"
<< ":";
cin >> guess;
guess = toupper(guess);

for (int r = 0; r < n-1; r++)
{
if (position[r] == guess)
{
cout << "correct guess";
// graphics where letter would show up
break;
}

else
{
cout << guess << " is not a letter in the word\n";
wrongGuess++;
break;
}

}
}

int main()
{

cout << "Would you like to play a game of hangman Y/N?";
char selection;
cin >> selection;
//sends the selection to upper case so that lower or upper case can be used and work

else
break;

cin >> selection;
selection = toupper(selection);
cout << "\n\n";
}
while (selection!='a'&&selection!='A'&&selection!='b'&&selection!='B'&&selection!='c'&&selection!='C'&&selection!='d'&&selection!='D')
{
cout << "Program terminated";
return 0;

}

Please use < code > tags around your source code, makes it much more readable :)

Secondly, what specifically is the problem?
