Thread: 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;

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.
