Задачка c++. Найдите величину s=(1+X)^m

include lt;iostreamgt;
using namespace std;

int main()
    double x;
    double xn = 1;
    int m;
    double eps = 0.001;
    int f = 1;
    int mn = 1;
    int i = 0;
    double an = 1;
    double s = 1;
    cout lt;lt; "x = ";
    cin gt;gt; x;
    cout lt;lt; "m = ";
    cin gt;gt; m;
    while (anlt;eps)
        mn = mn*(m-i);
        i++;
        f = f*i;
        xn = xn*x;
        an = mn*xn/f;
        s = s+an;
   
    cout lt;lt; "S = "  lt;lt; s;
return 0;


Пример:
x = 0.2
m = 5
S = 2.48832
