Very simple Fibonacci sequence generator in C++. It accepts a single command-line parameter, which is the quantity of numbers to generate.

fibonacci.cpp

#include <cstdlib>
#include <iostream>
using namespace std;

int main(int argc, char** argv)
{
	int i = 0;
	int n = atoi(argv[1]);
	int f[n];
	
	if(argc == 2)
	{
		for(i = 0; i <= n; i++)
		{
			if(i > 2)
			{
				f[i] = f[i-1] + f[i-2];
			}
			else
			{
				f[i] = 1;
			}
			
			cout << abs(f[i]) << endl;
		}
	}
	else
	{
		cerr << "Insufficient command-line parameters given." << endl;
	}
	
	system("pause");
	
	return 0;
