Write a C program to find the exponential series of 1+x+ x2/2! + x3/3! + ........ + xn/n!

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

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