Sum of Exponential Series

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

void main( )
{
    int x, n, fact, i, j;
    float sum=1;
    clrscr( );
    printf("Enter the 'x' value:");
    scanf("%d",&x);
    printf("\nEnter the 'n' value:");
    scanf("%d",&n);

        for( j=i ; j >=1; j--)
        fact=fact*j;
        sum=sum+(pow(x,i)/ fact);
    }
    printf("\nSum of the series : %f ",sum);
