Make this, only using while statements:

user inputs a number: (for example, 5)

* * * * *
* *
* *
* *
* * * * *
and makes a square of asterisks, with 5 asterisks on each side. Here's my code so far, and i'm stuck...

// Exercise 4.25 Asterisk square problem.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
using namespace std;

int main()
{
int number;
cout << "Enter a number to make a square with that many number of asterisks on each side: ";
cin >> number;

int count = 0, column = 0, wideness = 0, rows = 0;

cout << endl << endl << endl;

while (count < number)
{
cout << "* ";
count++;
}
cout << endl;

while (rows < number - 2)
{
cout << "*";

while (column < number-2)
{
cout << " ";
column++;
}
cout << " ";
cout << "*";
cout << endl;
rows++;
}

while (wideness < number)
{
cout << endl <<"* ";
wideness++;
}
return 0;
}

and it's not making me the box I want....

ok, the box has the number of asterisks on each side, boardering the square, that the user inputs... it won't let me do it, it keeps pushing the outside border of asterisks on the left side of the square, even in my program...

Edit your posts, and put both the squares and the C++ code in [code] tags.

Here's how I did it in Python:

(Toggle Plain Text)

def square (size):
	print "*" * size
	print ("*" + " " * (size - 2) + "*\n") * (size - 2),
	print "*" * size

Thank god for string multiplication. To do this in C++, replace every instance of the multiplication operator with a loop.

i didn't see anything in the project specs about the square being empty. was that left out, or did you just assume that? obviously, it would be much easier if the square were filled like:

supposed to be empty

bl00dninja · Apr 11th, 2005, 8:08 PM

ahhh. i'm always looking for the easy way out.

massive-war · Apr 11th, 2005, 8:18 PM

me too, too bad teachers don't.

you need to re-initialise your variables before you use them again... particullarly in the nested loop, heres some working code:

(Toggle Plain Text)

#include <iostream>
using namespace std;

int main()
{
	int number;
	cout << "Enter a number to make a square with that many number of asterisks on each side: ";
	cin >> number;
	
	int count = 0, column = 0, wideness = 0, rows = 0;
	
	cout << endl << endl << endl;
	
	while (count < number){
		cout << "* ";
		count++;
	}
	cout << endl;
	
	while (rows < number - 2){
		cout << "* ";
		column=0;
		while (column < number - 2)
		{
		cout << "  ";
		column++;
	}
	
		cout << "* ";
		cout << endl;
		rows++;
	}
	
	count=0;
	
	while (count < number){
		cout << "* ";
		count++;
	}
	return 0;
}

not sure what was going on with this:

Quote:

while (wideness < number)
{
cout << endl <<"* ";
wideness++;
}

you put an endl in there i assume that was a mistake...
