macOS Outputting a shape using C++

[USCtrojan08]

So I'm taking an intro to programming topics using C++. I have been using Xcode (project type: C++ tool) and TextEdit using the g++ compiler in the terminal concurrently.

I have yet to receive my textbook and I'm starting to feel a little behind. For our homework this weekend we have to create square by defining the boarder and character type.

The coding style should look like:
int main()
{
// Define variables border and answer as type char

// Define variable isSolid as type bool

// Ask if the square is solid and save to the variable answer

// based on answer, assign isSolid to true or false

// Ask second question to get a character border to draw

// Draw five lines based on the value of isSolid and the border character

return 0;
}

While the output may look like:

Draw a 5 by 5 square: is it solid? (y/n) y
Give me the character to draw: 1
11111
11111
11111
11111
11111
Press Q to Exit: q

Draw a 5 by 5 square: is it solid? (y/n) n
Give me the character to draw: a
aaaaa
a a
a a
a a
aaaaa
Press Q to Exit: q

Any help would be appreciated.

Thanks!

Use a nested loop. In the inner loop, print one of the character. In the outer loop, print a line break. You could do it without nesting, but if this is a beginning course, the nested loop is probably the intent.

Should be to late to claim this as your own (which is why I held off replying after your first responses advice) but a possible solution is presented below for the curious future reader.

#include <iostream>

int main()
{
	// Define variables border and answer as type char
	char	border, answer;	
	
	// Define variable isSolid as type bool
	bool	isSolid;

	while ( true )
	{
		while ( true )
		{
			// Ask if the square is solid and save to the variable answer
			std::cout << "\nDraw a 5 by 5 square: is it solid? (y/n) ";
			std::cin >> answer;
			
			// based on answer, assign isSolid to true or false
			if ( ('y' == answer) || ('Y' == answer) )
			{
				isSolid = true;
				break;
			}
			else if ( ('n' == answer) || ('N' == answer) )
			{
				isSolid = false;
				break;
			}
		}
		
		// Ask second question to get a character border to draw
		std::cout << "\nGive me the character to draw: ";
		std::cin >> border;
		
		// Draw five lines based on the value of 'isSolid' and the 'border' character
		for ( int i = 0; i < 5; i++ )
		{
#if 1
			// ... your line solution here ...
#else
			// ... because you wouldn't have covered stl strings yet
			std::string line(5, border);

			if ( isSolid == false )
			{
				if ( (i > 0) && (i < 4) )
				{
					line.replace(1, 3, 3, ' ');
				}
			}
#endif
			
			std::cout << "\n" << line;
		}

		// Ask third question to quit, else loop
		std::cout << "\nPress Q to Exit: ";
		std::cin >> answer;

		if ( ('q' == answer) || ('Q' == answer) )
		{
			break;
		}
	}

	return 0;
}
