Help making a diagonal line based off user input

[thunderbird]

Hello, I am new to c++ and just started a for fun online course a few weeks ago.

I created some code to make a square based off what the user inputs to how big the square should be. How can I edit this code to make it into a diagonal line?

EX: If user inputs 4: (Ignore the periods)
*
.*
..*
...*
Here is what I have to make a square that works:

#include <iostream>
#include <string>
using namespace std;
int main()
{
	int i, n, size = 0;
	string line;
	cout << "Enter the size of your shape:" << endl;
	cin >> size;
// Outputs a square into console.
	for (i = 0; i < size; ++i, line = "") {
		for (n = 0; n < size; ++n)
			line += '*';
		cout << line << endl;
	}
	cout << endl;
}

Any help would be appreciated! Thanks in advance :)

Hello thunderbird,

Welcome to the forum.

What you have to keep in mind is how many spaces you need to print before each '*'. It is a quick thought for now I may come up with something different tomorrow.

for (size_t lco = 0; lco < numLines; lco++)
{
	for (size_t lci	= 0; lci < lco; lci++)
	{
		std::cout << ' ';
	}

	std::cout << '*' << std::endl;
}

What you have is the inner for loop condition is based on the outer for loops counter. This determines how many spaces to print before you print the '*' and return to the top of the outer for loop.

Hope that helps,

Andy
