Write out a triangle

ok, i see it is a simple trade out of commands, I will start using it, thanks :)

You should be aware that although "\n" and "endl" look visually similar (in the actions they perfrom) they are different and it is advised to use "\n".

EDIT* Advised for this program ^

I would suspect that the point of the assignment is to use nested for loops.

Clever ways to simplify problems are much more fun, though. Here's mine:

#include <iostream>
using namespace std;

int main( int argc, char* args[] )
{
    char sign;
    int height;

    cout << "designate sign: ";
    cin >> sign;

    cout << "designate height: ";
    cin >> height;

    cout << endl;

    string line;
    for( int i = 0; i < height; ++i )
    {
        line += sign;
        cout << line << endl;
    }

    return 0;
}

Uh... Huh? Actually, they do almost exactly the same. In fact, if I had to guess, I'd say std::endl() just pushes an '\n' into the stream.

Doesn't endl also flush the stream?

That's what I thought.

[helios]

Streams are line-buffered. std::endl() flushes the stream as an indirect consequence of pushing the newline.
(I think.)

ok, got it, so there is a difference, thanks Mcleano and Bazzy
