    My chessboard

    here's my code and i need to get te outpu into a text file.
    the output is a simple chessboard. i tried using fstream, printf but couldn't make it work

    sorry for all the confusion in the earlier posts, i'm kinda desperate.
    this code works fine, but only the ouput should be displayed like it is and also saved to a textfile
    which must be named by the user.

    the code:
    #include<iostream>

    using namespace std;

    int main()
    {
    string character, b=" ",stop_go;//initialisation of variables
    int size;
    int n=1;

    while (n>0) //while loop so the user can draw multiple times

    {

    cout<<"Give Chessboard Size:"<<endl; //read-in chessboard information and save in variables
    cin>>size;
    //so only odd numbers will be used
    if(size%2==0)

    {
    cout<<"Only enter odd numbers; please try again"<<endl;
    continue;
    }
    cout<<"Give a Character for your chessboard:"<<endl;
    cin>>character;


    //begin drawing chessboard
    for(int k=1; k<=size //outer loop for vertical drawing


    {

    if (k%2==0)

    for (int i=1; i<=size;i++) //inner loop voor horizontal drawing

    {

    if (i%2==0) cout <<character;
    else cout<< b;

    }
    else


    for (int i=1; i<=size;i++)

    {

    if (i%2==0) cout <<b;
    else cout<< character;

    }

    cout<<endl;
    k++;


    }

    //give user the choice to exit or draw again
    cout<<"Press 'e' to exit or 'd' to try again \n please draw chessboard"<<endl;
    cin>>stop_go;
    if (stop_go=="e") n=0;
    if (stop_go=="d") n=1;



    }


    system("pause");
    return 0 ;

    }

    Re: My chessboard

    You think people are telling you to use code tags just because they like typing?

    You'll find help drying up if you keep starting multiple posts with the same question and don't take advice that's given to you.

    sorry for all the code without tags
    Code:
    #include<iostream>

    {
      string character, b=" ",stop_go;//initialisation of variables

      int n=1;
    
     while (n>0)    //while loop so the user can draw multiple times
    
     {
    
     cout<<"Give Chessboard Size:"<<endl; //read-in chessboard information and save in variables
     cin>>size;
                         //so only odd numbers will be used
        if(size&#37;2==0)
    
            {

                     }

    Re: My chessboard

    that's my code, i need to get the ouput into a textfile that will be name by the user.
    i tried to integrate the isdigit function, but it didn't work.
    the program crashes when a letter entered as size instead of a number, can that be resolved?
    thanks in advance

    Re: My chessboard

    I modified your code as follows so that it ouputs the board to a user specified file as well.
    Code:
    #include<iostream>
    #include <fstream>
    #include<string>
    
    using namespace std;
    
    int main()
    {
    	string character, b=" ",stop_go;//initialisation of variables
    	int size;
    	int n=1;
    
    	string fname;
    	cout<< "File name please: ";
    	cin >> fname;
    	ofstream outf(fname.c_str());
    
    	while (n>0)    //while loop so the user can draw multiple times
    
    	{
    
    		cout<<"Give Chessboard Size:"<<endl; //read-in chessboard information and save in variables
    		cin>>size;
    		//so only odd numbers will be used
    		if(size%2==0)
    
    		{
    			cout<<"Only enter odd numbers; please try again"<<endl;
    			continue;
    		}
    		cout<<"Give a Character for your chessboard:"<<endl;
    		cin>>character;
    
    
    		
    		//begin drawing chessboard
    		for(int k=1; k<=size;)   //outer loop for vertical drawing
    
    
    		{
    
    			if (k%2==0)
    
    				for (int i=1; i<=size;i++)   //inner loop voor horizontal drawing
    
    				{
    
    					if (i%2==0) { cout <<character; outf << character; } 
    					else { cout<< b; outf << b;}
    
    				}
    			else
    
    
    				for (int i=1; i<=size;i++)
    
    				{
    
    					if (i%2==0) { cout <<b; outf << b;}
    					else {cout<< character; outf << character; }
    
    				}
    
    				cout<<endl;
    				outf << endl;
    				k++;
    
    
    		}
    
    		//give user the choice to exit or draw again
    		cout<<"Press 'e' to exit or 'd' to try again \n please draw chessboard"<<endl;
    		cin>>stop_go;
    		if (stop_go=="e") n=0;
    		if (stop_go=="d") n=1;
    
    
    
    	}
    
    
    	system("pause");
    	return 0  ;
    
    }
