[C++] Drawing a window border with asterisks

Hello, I am just wondering if there is an easy way to do the following in my constructor

IOScreen(int row, int col, int width, int height); sets the row, col, width, height attributes of the IOScreen to the corresponding incoming values in the argument list. If an IOScreen is made using this constructor, it means that the IOScreen window is not a full-screen size window. (i.e it will only cover the screen partially and when it is displayed, it will show a frame using the asterisk character on the border line characters of the window

I assume Ill want to use my row, col, width and height in some kind of for loop to make the border line characters of the window but am unsure of the conditions to do so. Appreciate any help whatsoever.

Thanks in advance.

Edit: Think I forgot to mention that I can use a function I wrote called cio_cursor

/* Places cursor at specified row/column number */
void cio_cursor(int row, int column){

So far I have got

Code:

IOScreen::IOScreen(int row, int col, int width, int height){
	this->row = row;
	this->col = col;
	this->width = width;
	this->height = height;
	cio_start();
	cio_cursor(row,col);
	// Adjust window settings for this constructor using height and width
}

Taking what you have already coded:

Code:

#include <string>

IOScreen::IOScreen(int row, int col, int width, int height){
	this->row = row;
	this->col = col;
	this->width = width;
	this->height = height;
	cio_start();
	cio_cursor(row,col);
	// Adjust window settings for this constructor using height and width

	std::cout << std::string(width,'*');
	for (int i=1; i<height-1; ++i)
	{
		cio_cursor(row+i,col);
		std::cout << '*';
		cio_cursor(row+i,col+width-1);
		std::cout << '*';
	}
	//Draw the bottom of the border
}

Replace cout with the appropriate output command, if you are using something different to output characters. Instead of std::string, you could also use a for-loop to draw the top of the border.

Will this draw the bottom row?

>Will this draw the bottom row?
No, just the top and sides.

Unsure of how to draw the bottom

Code:

	cio_cursor(row,col);
	std::cout << std::string(width,'*');

The above two lines draw the top. So what I would recommend is changing this line:

Code:

	std::cout << std::string(width,'*');

into a for-loop to draw the top. If you can do that then you can easily draw the bottom.

The key to getting code to work is to play with it. Write a couple of lines of code, compile it, run it, and see what it does. Then make changes until it works. Then add more code.
