okay I came up with something a little more complex, but it's still not working. I know it's somewhere within my functions (either the bools or whatnot)......basically it's not telling them they entered an invalid date.

Any help?? I didn't put it in there, because I can't figure out where it goes logically.

hello!

I need a program that validates the imput of dates. (Checks for leap years etc.)

The user enters: mm/dd/yyyy

The problem is, I have trouble with complex programs. I came up with this program, but i know it's too basic for what she wants. I need to have arrays in there, but i don't know how. I would love any help considering I'm bad at understanding this subject.

:)

could someone help me ???!!!

I just don't understand where I would add a "Margin" to???

I've tried all of the variables

Think harder. A good night's sleep helps.

i have thought long and hard..........

It's due tomorrow at 8 AM.

I would love to sleep on it.....but seriously my mental capacity for figuring this out is less than a two-year old.

I've been trying for the past hour......how sad is that !!

Please help me.....!!! makes the difference between a C and a B.

Okay, I think I understand the logic.

I'm so tired right now.....where would that fit in?? would I have to make another function?????

void displayStars (int, int);

int main ()
{ 
   int row, column;
   char again;

      do
           {
	
	cout << "Enter the number of rows and columns: ";
	cin >> row >> column;

	while (column < 2 || column > 60 && row < 2 || row > 60)
	{
	cout << "Invalid values for rows and columns" <<endl;
	cout << "Please enter values between 2 - 60: " ;
	cin >> row >> column;
	}
	cout << endl << endl;
	displayStars(row, column);										cout << endl << endl;
	cout << " Do you want to create another rectangle? (Y/N) ";
	cin >> again;
	} while (again == 'Y' || again == 'y');
	return 0;
} 


void displayStars(int width, int height) 
{
for (int across = 0; across < height; across++) 
	{
	for (int down = 0; down < width; down++) 
	{
	if ((down == 0) || (down == width - 1)) 
	{
	cout << "*";
	} 
	else if ((across == 0) || (across == height - 1)) 
	{
	cout << "*";
	 } 
	 else 
	{
	cout << " ";
	 }
            }
        cout << endl;
		}
}

Thanks soooo much :)

Hello! I have a program that generates a rectangle based on width and height.

---I just need to figure out how to center this if the screen was 80 characters wide.------

void drawRect(int width, int height) {
    for (int i = 0; i < height; i++) {
        for (int j = 0; j < width; j++) {
            if ((j == 0) || (j == width - 1)) {
                cout << "*";
            } else if ((i == 0) || (i == height - 1)) {
                cout << "*";
            } else {
                cout << " ";
            }
        }
        cout << endl;
    }
}

Okay I see! It makes sense to me! THANKS A LOT :)

One more added detail, I need to make the rectangle centered.

I need to assume the screen is 80 characters wide.

THANKS A LOT :) OH man, I'm slow at this stuff. I need to start on my history exam!

It didn't work. Oh no, i have another exam to study for tonight.

I've been sick and I'm so far behind.

This is my entire program:

#include <iostream>
using namespace std;


void displayStars (int, int);

int main ()
{ 
    int row, column;

    cout << "Enter the number of rows and columns: ";
    cin >> row >> column;

    while (column < 2 || column > 60 && row < 2 || row > 60)
    {
    cout << "Invalid values for rows and columns" <<endl;
    cout << "Please enter values between 2 - 60: " ;
    cin >> row >>column;
    }

    displayStars(row, column);      
    return 0;
} 


void displayStars (int rows, int cols)
{

   for (int across = 0; across < rows; across++)
     {
          if (across == 0 || across == rows)
    {
           for (int down = 0; down < cols; down++)
        cout << "*";
        cout << endl;
    }
           else
    {
            for (int down = 0; down < cols; down++)
               {
                               if (down == 0 || down == cols)
             cout << "*";
                               else
                                                  cout << "  ";
                              }
      }
       cout <<endl;
    }
}

Hi I'm new to C++ and to here.

I have an assignment.

Make a HOLLOW rectangle using Functions.

Have the user imput the amount of rows and columns....and border width .

It should look something like this (It's supposed to be a HOLLOW rectangle) :

Enter number of rows and columns:
Enter Border width:


**********
*        * 
*        *
*        *
**********

I'm only able to get this:

***********
***********
***********
***********
***********

here's the part of my code that I know is affecting it :

//This function displays a square made of astericks

void displayStars (int rows, int cols)
{

for (int across = 0; across < rows; across++)
    {
         for (int down = 0; down < cols; down++)
         cout << "*";
         cout <<endl;
}
}
