Thread: Connect 4 game

Hi all, i'm new at c++ so please be patient with me .I'm writing connect 4 game and stuck at checkwin function.

Here's my code:

Code:

#include <iostream>
#include <cstdlib>


using namespace std;


char place[6][7];
int iPlayerTurn=1, turn, win;
int pos0=5, pos1=5, pos2=5, pos3=5, pos4=5, pos5=5, pos6=5;
int tie=0; // if the board is full, game ends as draw.
char cPlayerMark; // player mark, X and O.


void drawBoard() // function to draw a board
{
    cout << " 1   2   3   4   5   6   7" << endl;
    for(int a=0; a<=5; a++)
    {
        for(int b=0; b<=6; b++)


            cout << char(218) << char(196) << char(191) << " ";
            cout<<'\n';


        for(int b=0; b<=6; b++)


            cout<<char(179)<<place[a][b]<<char(179)<<" ";
            cout<<'\n';


        for(int b=0; b<=6; b++)


            cout<<char(192)<<char(196)<<char(217)<<" ";
            cout<<'\n';


    }
}


int checkwin() // totaly stuck here
{


}


int main()
{
   drawBoard();


   do
   {
       cout << "Player " << iPlayerTurn << " turn: " << endl;
       cin >> turn;


       if(iPlayerTurn == 1) // sets player mark between X and O
       {
           cPlayerMark = 'X';
       }
       else
       {
           cPlayerMark = 'O';
       }


       if(iPlayerTurn == 1) // after 1 move changes the player
       {
           iPlayerTurn = 2;
       }
       else
       {
           iPlayerTurn = 1;
       }


       if(turn == 1)
       {
            place[pos0][0] = cPlayerMark;
            pos0--; // every time you place mark, it goes up by 1 column
            tie++; // not sure if this necessary , but if tie == 42, game is draw, because then its full board.
       }
       else if(turn == 2)
       {
           place[pos1][1] = cPlayerMark;
           pos1--;
           tie++;
       }
       else if(turn == 3)
       {
           place[pos2][2] = cPlayerMark;
           pos2--;
           tie++;
       }
       else if(turn == 4)
       {
           place[pos3][3] = cPlayerMark;
           pos3--;
           tie++;
       }
       else if(turn == 5)
       {
           place[pos4][4] = cPlayerMark;
           pos4--;
           tie++;
       }
       else if(turn == 6)
       {
           place[pos5][5] = cPlayerMark;
           pos5--;
           tie++;
       }
       else if(turn == 7)
       {
           place[pos6][6] = cPlayerMark;
           pos6--;
           tie++;
       }
       else
       {
           cout << "Wrong number." << endl; // if wrong move, player turn and mark stays the same
           if(cPlayerMark == 'X')
           {
               iPlayerTurn = 1;
           }
           if(cPlayerMark == 'O')
           {
               iPlayerTurn = 2;
           }
       }




       drawBoard();
   }while(tie!=42);
