Write a program that approximates the value of e by the following partial sum: \(\sum_{n=0}^{N}\frac{1}{n!}=2+\frac{1}{2}+\frac{1}{3!}+ \cdots + \frac{1}{N!}\)

You should continuously add only the terms greater than \(10^{-10}\).

Difficulty level
This exercise is mostly suitable for students 
#include<stdio.h>

void main() {

	int i;
	double u,s;

 	s=u=1;
	for(i=1;u>1e-10;i++) 
	{
		u=u/i;
		s=s+u;
	}
	printf("e = %lg, #terms = %d\n",s,i+1);

	getch();
}
