Sum of series 1/1!+2/2!+3/3!+4/4!+5/5! + - - - - - - -


Write a program to calculate the sum of the following series:
1/1!+2/2!+3/3!+4/4!+5/5!+6/6!+ - - - - - - -




#include <iostream>
using namespace std;
int main()
{
 double fact,term,sum=0;
 int length;
 cout << "This program will disply the sum of following series... \n"<<endl;
 cout << "1/1!+2/2!+3/3!+4/4!+5/5!+ - - - - - - \n"<<endl;
 cout << "Enter Length of the series: ";
 cin >> length;
 for (int i=1;i<=length;i++)
 {
  fact=1;
  for (int j=1;j<=i;j++)
  {
   fact=fact*j;
  }
  term=i/fact;
  sum=sum+term;
 }
  cout << "Sum is: "<< sum << endl;
  cout <<endl;

 return 0;
}

}
