Extra new line character without code

OK, so I have completed a homework assignemnt, and the code is correct; however, it is not running as smooth as I wish for it to. I am posting this purely out of curiosity. The program prints out a diamond (consisting of asterisks) where the size is based on a # received from the user. The problem is that after the diamond is printed it prints out a lot of extra lines. Here it is!

Code:

---



#include<iostream>
using namespace std;

int main(){

        int width,                //used to receive width from user
                star = 0,        //used to increment asterisks and is defaulted to 0 as the initial do-while loop must print only 1 star
                space;                //used to increment the spaces before asterisks
        do{
                cout << endl << endl << "Welcome to the Asterisk Diamond Generator"  << endl << endl;
                cout << "Please enter an odd number which will be the width of the diamond: ";        //receive width variable
                cin>>width;
                if(width &#37; 2 == 0)        //prevent program from continuing with an even #
                        cout <<"\nWell, that's almost and odd number, but try again...\n\n\n";
       
        }while(width % 2 == 0);

        space = (width/2);                //set the initial spacing for the star
        cout<< "\n\n\n\n\n";                //clear room for a good drawing

        do{                                                                        //draw the top half
                for(int i = 0; i <= space; i++)
                        cout<< " ";
                for(int j = 0; j <= star; j++)
                        cout<< "*";

                cout<< endl << endl;
                star += 2;
                space -= 1;
        }while(star <= width);


        space = 1;                        //set the initial spacing and star count for the bottom half
        star = (width - 3);


        do{                //draw the bottom half
                for(int i = 0; i <= space; i++)
                        cout<< " ";
                for(int j = 0; j <= star; j++)
                        cout<< "*";

                cout<< endl << endl;
                star -= 2;
                space += 1;
        }while(space <= (width+1));

        cout<< "Scroll up to see the diamond.\n\n";
        cout<< "Thank you for using the Asterisk Diamond Generator." << endl << endl << endl;

        return 0;
}

Any advice on this problem would be grrrrrreat!

How many is lots? Are you aware of this part of your program?

Code:

---

cout<< "Thank you for using the Asterisk Diamond Generator." << endl << endl << endl;

Thank you for taking a look, but that is not where the extra spaces are. Here is the code again with notation about where the extra spaces seem to occur. To see this in action, you will need to compile the program because the spaces do seem to occur without any code creating them as far as I can tell.

Code:

---



#include<iostream>
using namespace std;

int main(){

        int width,                //used to receive width from user
                      star = 0,        //used to increment asterisks and is defaulted to 0 as the initial do-while loop must print only 1 star
                space;                //used to increment the spaces before asterisks
        do{
                cout << endl << endl << "Welcome to the Asterisk Diamond Generator"  << endl << endl;
                cout << "Please enter an odd number which will be the width of the diamond: ";        //receive width variable
                cin>>width;
                if(width % 2 == 0)        //prevent program from continuing with an even #
                        cout <<"\nWell, that's almost and odd number, but try again...\n\n\n";
       
        }while(width % 2 == 0);

        space = (width/2);                //set the initial spacing for the star
        cout<< "\n\n\n\n\n";                //clear room for a good drawing

        do{                                                                        //draw the top half
                for(int i = 0; i <= space; i++)
                        cout<< " ";
                for(int j = 0; j <= star; j++)
                        cout<< "*";

                cout<< endl << endl;
                star += 2;
                space -= 1;
        }while(star <= width);


        space = 1;                        //set the initial spacing and star count for the bottom half
        star = (width - 3);


        do{                //draw the bottom half
                for(int i = 0; i <= space; i++)
                        cout<< " ";
                for(int j = 0; j <= star; j++)
                        cout<< "*";

                cout<< endl << endl;
                star -= 2;
                space += 1;
        }while(space <= (width+1));

/*

                 

 EXTRA SPACES OCCUR HERE



*/
        cout<< "Scroll up to see the diamond.\n\n";
        cout<< "Thank you for using the Asterisk Diamond Generator." << endl << endl << endl;

        return 0;
}

Modify the loop for the bottom half to look like this:

Code:

---

        do{            //draw the bottom half
                for(int i = 0; i <= space; i++)
                        cout<< " ";
                for(int j = 0; j <= star; j++)
                        cout<< "*";

                cout<< endl << endl;
                star -= 2;
                space += 1;
                cout << "Space: " << space << ", Star: " << star << "\n";
        }while(space <= (width+1));

I think you'll find it enlightening.

Haha, awesome. I feel so dumb now...

Thanks for helping me out with that!
