I have to calculate the value of e
e=1+1/1!+1/2!+1/3!+1/4!+1/5!+1/6!+1/7!+1/8!........
I need to use recursion function.
I can cal. the power of n(n!) but I dont have any idea on how to sum of them.
Could someone give me hints on this. thk
Code:#include<stdio.h> #include<math.h> double exp(double term){ int n; if (term==0) return 1; if (term==1) return 1; else { n= term * exp (term-1); return 1/n + 1/(exp(n-1)); } } int main(){ float r; r=exp(7); printf("Result=%f",r); getchar(); }
