series problems

1+x+(x2/2!)+(x3/3!)+………………………………………+(x^n/n!) Write a program to show the sum of he series when x & n is input through the keyboard.

#include<stdio.h>
#include<math.h>

void main()
{
int x,n,i,j,fact;
float sum=1;
clrscr();
printf("\nEnter the Value of 'x' : ");
scanf("%d",&x);
printf("\nEnter the value of 'n' : ");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
fact=1;
for(j=1;j<=i;j++)
{
fact*=j;
}
sum=sum+(pow(x,i)/fact);
}
printf("\nSum of the Series : %5.2f",sum);
getch();
}

==============

C program for the series: 1+x+x^2/2+x^3/3+.....+x^n/n?

include<math.h>

int i, x, n;
int sum = 1;
//get n from user
for(i = 1; i < n; i++)
{
sum += pow(i, x)/x;
}
return sum;
