moorec's asdf dir #1

[moorecm]

I was looking through some old directories this afternoon and stumbled upon a few programs that I had written and saved for reference. I figured it might be fun to hear your critique.

First, as a response to the common homework assignment to make a triangle of asterisks is this template metaprogram:

#include <iostream>

template< int N >
struct Row {
    std::string value;
    Row() { value += '*' + Row< N - 1 >().value; }
};
template<>
struct Row<0> {
    std::string value;
    Row() { value += '\n'; }
};

template< int N >
struct Pyramid {
    std::string value;
    Pyramid() { value += Pyramid< N - 1 >().value + Row< N >().value; }
};
template<>
struct Pyramid<0> {
    std::string value;
};

int main()
{
    std::cout << Pyramid< 5 >().value;
    return 0;
}
