endl

[shawnrb10]

So I'm trying to complete this for an assignment. I need to print a pyramid of stars using 2 ways: the first with 4 cout statements; and the second with only 1 cout statement. However, on my second version, I can't manage to get the stars on different lines. Where do I put the endl so that it comes up with the same result as version 1?


This is my first program ever in C++.

using namespace std;

const string line1 = "   *";

const string line4 = "*******";


int main()
{

	cout << "This is version 1 with four cout statements." << endl;
	cout << line1 << endl;
	cout << line2 << endl;
	cout << line3 << endl;
	cout << line4 << endl;

	cout << "This is version 2 with only one cout statement." << endl;
	cout << line1 << endl << line2 << endl << line3 << endl << line4<< endl;

	return 0;
}

thank you!!
But I would love to understand what is different from mine.
I noticed the editor places red marks after each line# in my version, but not in yours. The red marks are placed even before compiling.

I fail to see what is different...

did you copy it from a book? i just deleted your red dots.

yes, I'm so stupid I copy/pasted this from the textbook to "save time"...

Thanks buddy!

You can use the new line character '\n' instead of endl. \n doesn't flush the output buffer like endl does so you can use that and then have an endl at the end of the statement.
