It's hard to help you without knowing a little about your experience with C++. Are you doing C++ at university? How long have you been studying? How much C++ do you know? Have you ever created a game in C++ before?

Now I have some mistake about printing the board.
here is the code

Code:

#include <iostream>
#include<string>
#include<iomanip>
using namespace std;
const int maxrow = 6;
const int maxcol = 7;
void logo();
void playername(string name);
void rules();
void initBoard(char board[][maxcol], int maxrow, int maxcol);
void printBoard(char board[][maxcol], int maxrow, int maxcol);
int main()
{
	char board[maxrow][maxcol];
	string name;
	logo();
	playername(name);
	rules();
	initBoard(board, maxrow, maxcol);
	printBoard(board, maxrow, maxcol);
}
void logo()
{
	cout<<"------------Welcome to Connect 4 ----------------"<<endl;
	cout<<"     ************Connect*************"<<endl;
	cout<<"    **********************************"<<endl;
	cout<<"   *****************4******************"<<endl;
	cout<<"  *****************4*4******************"<<endl;
	cout<<"  ****************4**4******************"<<endl;
	cout<<"  **************4444444***************"<<endl;
	cout<<"   *****************4****************"<<endl;
	cout<<"    ****************4***************"<<endl;
	cout<<"\n\n"<<endl;
}
void playername(string name)
{
	cout<<"What is player's name : ";
	cin>>name;
	cout<<"Hi "<<name<<endl;
}
void rules()
{
	cout<<"The following is the rules of the Connect 4 : \n";
	cout<<"1. Each player in his turn drops one of his checkers down any of the slots \n   in the top of the grid. \n";
	cout<<"2. The play alternates until one of the players gets four checkers of his \n   colour in a row. The four in a row can be horizontal, vertical, or diagonal.\n";
	cout<<"3. The first player to get four in a row wins.\n";
	cout<<"4. If the board is filled with pieces and neither player has 4 in a row, \n   then the game is a draw.\n";
}
void initBoard(char board[][maxcol], int row, int col){
	for (int i = 0; i < row; i++)
	{
		for (int j = 0; j < col; j++)
		{
			board[i][j] = ' ';
		}
	}
}
void printBoard(char board[][maxcol], int row, int col)
{
	for (int i = 1; i <= row; i++){
		for (int j = 1; j <= col; j++){
			cout << setw(3) << board[row][col]<<"| ";
		}
		cout << endl;
	}
	for (char i = 'A'; i <= 'G'; i++){
		cout << setw(3)<<i<<"  ";
	}
	cout << endl;
}

why there is some 'n'???
what's the problem??

The problem is you are going outside the bounds of your board array:

Code:

			cout << setw(3) << board[row][col]<<"| ";

I think what you meant here was:

Code:

			cout << setw(3) << board[i][j]<<"| ";

As it happens, there is another problem with printBoard(). Remember indexing starts at 0, not 1. Instead of

Code:

	for (int i = 1; i <= row; i++){
		for (int j = 1; j <= col; j++){

you should have

Code:

	for (int i = 0; i != row; ++i){
		for (int j = 0; j != col; ++j){

Also, I believe you meant to pass that string by reference in playername. Instead of:

Code:

void playername(string name)

you should have

Code:

void playername(string& name)

thx!!!
if i have any problems, i will ask you again

how can i ask the player to input into the board???
