Slip 2 - B) Write a program to calculate sum of following series up to n terms. Sum=X+X^2 /2!+X^3 /3!+......

Solution:

#include<math.h>

#include<stdio.h>

    int fact(int index)

    {

    int f = 1, i;

    for(i = 1; i <= index; i ++)

    {

        f = f*i;

    }

    return f;

    }

// Driver Code

void main()

{

    int x = 1;

    int n = 2;

    double sum = 0,   m;

    // Sum of n-1 terms starting from 2nd term

    int i;

    for (i = 1; i < =n; i++) {

    m =  pow(x, i) / fact(i);

    sum = sum + m;

   }

    printf("\n%.4f", sum);

    getch();

}
