Mein Code dazu...

:confused: 
#include <iostream>
#include <math.h>
using namespace std;

#define xanf            2
#define xend            8       
#define n               1000
#define delta_x         ((xend-xanf)/n)
double x;
double delta_x=((xend-xanf)/n);
int main(int na=0)
{
    for(x=2.; na!=n&&xanf<=x&&x<=xend; x=x+delta_x)
    {
              na++;
              cout << na << " _- " << x << "\n";
    }

    system("PAUSE");
    return 0;
}

Danke!
