[C++] - 6x6 board game

[kevindurant95]

Hi, I have a project exercise in c++ language. I have to admit I'm not so good in programming right now, so please try to help me.
The exercise:
Board Game. Board is 6x6 (36 fields). It's for two players (one computer - he's playing random). The players in turns add the stones to the board (all of stones are the same and one stone=one field). If after one player puts the stone on the board and 6 or 3 the stones will be in one line (horizontally, upright or aslant), he will receive 2 points (when it's 6) and 1 point(when it's 3). The game ends, when all of the fields are full.
The board has to look something like this: http://oi62.tinypic.com/2edvyw5.jpg

The stone should be '#', but it's indifferently. Could you give me some advices?

I have had something like this yet.

 #include <cstdlib>
#include <iostream>
#include <iomanip>

using namespace std;

void draw_board()
{ 
     for (int i=0;i<6;i++)
     {
     cout << " +-----+-----+-----+-----+-----+-----+"<<endl;
     cout << " |"<< setw(6) <<"|" << setw(6) <<"|" << setw(6) <<"|"<< setw(6) <<"|"<< setw(6) <<"|"<< setw(6) <<"|"<<endl;
     cout << i+1 <<"|"<< setw(6) <<"|" << setw(6) <<"|" << setw(6) <<"|"<< setw(6) <<"|"<< setw(6) <<"|"<< setw(6) <<"|"<<endl;
     }
     cout << " +-----+-----+-----+-----+-----+-----+"<<endl;
     cout << "    A     B     C     D     E     F   "<<endl;
     cout << endl << endl;
}

void choose_field()
{
     char sign;
     int line;
     int column;
     cout <<"Line: ";
     cin >> line;
     cout <<"Column: ";
     cin >> column;
          if(column==1)
          {
          sign='A';
          }
          if(column==2)
          {
          sign='B';
          }
          if(column==3)
          {
          sign='C';
          }
          if(column==4)
          {
          sign='D';
          }
          if(column==5)
          {
          sign='E';
          }
          if(column==6)
          {
          sign='F';
          }
          
     if (line>=1 and line<=6 and column>=1 and column<=6)
     cout << "Chosen field is:  " <<sign<<line << endl;
     else 
     cout << "This field doesn't exist: " << endl;
}




int main ()
{
draw_board();
choose_field();
system("pause");
return 0;
}

But it doesn't fix. Thanks for all of the answers.

You use = when you should be using ==.
= is assignment.
== is compare equality.

[kevindurant95]

I've changed it already, but thanks :) I would like to change my code and my drawing function to something compared with array.

[AbstractionAnon]

I would like to change my code and my drawing function to something compared with array.

You don't actually have a board allocated in your program, such as:

char board[6][6];

Then you're going to need to initialize the board

void init_board ()
{  for (int r=0; r<6; r++)
      for (int c=0; c<6; c++)
        board[r][c] = ' ';
}

Once the user enters the line and column, you're going to need to place a stone on the board:

    board[line-1][column-1] = '#';

Then you need to check if the placed stone is one of three or size in a row and adjust the players score accordingly.
You need a computer turn to randomly select an empty field.
You need to check if the computer's turn was one of three or six in a row and adjust the computer's score accordingly.
You need a loop that continues until the board is full.
And you need to change draw_board so that it displays the contents of the board in the proper places.

[kevindurant95]

Uhmmm, but how can I made my draw_board function related with an array?

[AbstractionAnon]

Is that so hard to figure out? Iterate through the rows and columns of the board.

void draw_board()
{ 
    for (int r=0;r<6;r++)
    {  cout << " +-----+-----+-----+-----+-----+-----+"<<endl;
        cout << " |"; 
        for (int c=0; c<6; c++)
            cout << "  " << board[r][c] < "   |"; 
        cout << endl;
        cout << i+1 <<"|"<< setw(6) <<"|" << setw(6) <<"|" << setw(6) <<"|"<< setw(6) <<"|"<< setw(6) <<"|"<< setw(6) <<"|"<<endl;
     }
     cout << " +-----+-----+-----+-----+-----+-----+"<<endl;
     cout << "    A     B     C     D     E     F   "<<endl;
     cout << endl << endl;
}

I have something like this. But when i type a field for example A5, '#' doesn't appear. What should i change?

[AbstractionAnon]

After you prompt the user for his play (rysuj_kamien), you stop.
You want to display the board again, so you need to call rysuj_plansze again.

int main ()
{   inicjuj_plansze();
    rysuj_plansze();
    wybierz_pole();
    rysuj_kamien();
    rysuj_plansze();
    system("pause");
    return 0;
}

Thanks. I have a couple of questions again. What should I do, when I want to change the sign from "#" to
###
###
And how can I count the punctation?
Thanks for all your advices :)

[kevindurant95]

And how can I generate the computer player moves? And avoid double typing of one field?
Sorry for my stupidity, but I'm new in c++ programming.

[AbstractionAnon]

What should I do, when I want to change the sign from "#" to ...

You really need to make an attempt to do this yourself. I can show you the code, but you will learn more if you try to do it your self.

void rysuj_plansze()
{   for (int i=0;i<MAX_WIERSZ;i++)
    {   //  First line
        cout << " +-----+-----+-----+-----+-----+-----+"<<endl;
        // second line 
        cout << " |"; 
        for (int j=0; j<MAX_KOLUMNA; j++)
            if (board[i][j] == '#')
              cout << " ###  |"; 
            else
              cout << "     |";
        cout << endl;
        // Third line
        cout << " |"; 
        for (int j=0; j<MAX_KOLUMNA; j++)
            if (board[i][j] == '#')
              cout << " ###  |"; 
            else
              cout << "     |";
        cout << endl;
       }
     // Bottom line
     cout << " +-----+-----+-----+-----+-----+-----+"<<endl;
     cout << "    A     B     C     D     E     F   "<<endl;
     cout << endl << endl;
}

And how can I count the punctation?

I'm not sure what you mean by that. Are you talking about counting if there are 3 or 6 cells in a row?

how can I generate the computer player moves?

Generate two random numbers (row, col) between 0 and 5.
Test if the cell is occupied. If it is, then loop back and generate another pair of numbers until you find a cell that is not occupied.

[kevindurant95]

Thanks. I'm learning better, when I see the solution. Yes, I'm talking about counting if there are 3 or 6 cells in a row, in a column or aslant. And how can I generate two numbers?

[AbstractionAnon]

I'm talking about counting if there are 3 or 6 cells in a row, in a column or aslant.

I'm not going to write it for you. Best way to start is work it out on paper.

If the player (or computer) places a marker in column x, then see if all cells in the column are filled (6 in a column). Check if all cells in the row are filled (6 in a row). I'll leave the diagonals to you.

If it's not 6 in a row, then check two cells above are filled or two cells below are filled, check if one above and one below are filled (3 in a col). Do the same for the current row. Keep in mind that one or two cells above and one or two cells below might not be valid locations. Same with 1 or 2 cells to the left or right.

And how can I generate two numbers?

Ok. But now, when I'm typing the field like 5x6 (5F), two symbols appear. My code right now is:

[AbstractionAnon]

Line 75: You have a problem when you enter 6 for either row or col.
e.g. numer_wiersza<=MAX_WIERSZ-1 compares the row to 5 and returns false causing "takie pole nie istnieje" to be displayed. Because you clear the screen before displaying the board, you don't see the error and the code proceeds with a possibly invalid value.

You need a loop within wybierz_pole so that it only exits when row and col are valid and continues to prompt if they are not valid.

How can I check if the field is full or no?

[AbstractionAnon]

You initialized the board to spaces (line 17). Simply check if board[i][j] contains a space or a #.

[kevindurant95]

inicjuj_plansze();
    for (int i=0 ; i<36 ;i++)
    {
    rysuj_plansze();
    wybierz_pole();
    for( int i = 0; i < MAX_WIERSZ; i++ ) {
        for( int j = 0; j < MAX_KOLUMNA; j++ )
             if (board[ i ][ j ] = ' ') ;
             else cout << "this field is full"; }
    rysuj_kamien();
    system( "cls" );

like this?

[AbstractionAnon]

Not really. That's going to display "this field is full" for every cell that is not a space. This is perfect for a function, rather than trying to test inline.

Try this:

bool isBoardFull ()
{  for (int i=0; i<MAX_WIERSZ;  i++) 
   { for( int j=0;  j<MAX_KOLUMNA; j++)
      {  if (board[i][j] == ' ')
             return false;  // No point in checking further
      }          
    }
    return true;  // No spaces found
}

Note: Line 8, you're using the assignment operator, not the equality operator.

[kevindurant95]

I used your code, but where I should make "cout << "this field is full" ?
And when I delete system("cls") I see, that when new board appears, the first line is moved to the right. I modified my code, I used indicators, what do You think?

I have a code like this:

#include <cstdlib>
#include <iostream>
#include <iomanip>

using namespace std;
