math sum problem

[Smatik]

i m trying to solve the following equation:

1-x^2/2 + x^3/3 - x^4/4 + x^5/5 + ....x^n/n

where value of x and n are obtained by the user.
I made the following program:

#include<iostream.h>
#include<math.h>
void main()
{
    int total=1;
    double x;int n;
    cout<<"enter value of x";
    cin>>x;
    cout<<"enter value of n";
    cin>>n;
    for (int i=2;i<=n;i++)
        {   if(i%2!=0)
            total+=double pow(double x,int i)/i;
            else total-=double pow(double x,int i)/i;
        }
    cout<<"\n"<<total;
}

total should be type double, not int.

This line: total+=double pow(double x,int i)/i;
should read: total += pow(x, i)/i;

total+=double pow(double x,int i)/i;  →→  total+=pow(x, i)/i;
