    Thank you in advance.

    ln n/e^n (from n=1 to infinity)

    Write a C program which will find the sum of the N-terms of the above
    convergent series. The program will consist of a MAIN function and a

    Within the MAIN function.
    . Number of terms N will be read from the standard input.
    . N will be passed to the function as an argument.
    . Sum of the N terms(return value from the function) will be printed.

    This is not a difficult assignment and you can easily get it done with guidance from us, but you have to show some work of your own, we will not do the entire thing for you. Even if you do get the answer from somewhere else, trust me mate, it will be a total waste of your time on the long run. Nobody can learn for you but yourself. You just need to get yourself to start.

    I suggest you start off with a program skeleton identifying the functions you need, the variables you will need, the includes and how you plan to approach the problem. Then, we will move on from there.
    1. Get rid of gets(). Never ever ever use it again. Replace it with fgets() and use that instead.
    2. Get rid of void main and replace it with int main(void) and return 0 at the end of the function.
    3. Get rid of conio.h and other antiquated DOS crap headers.
    4. Don't cast the return value of malloc, even if you always always always make sure that stdlib.h is included.
