Im a loser highschooler so Im going to use this as my excuse to fail if I do fail at this.

Math.h lets you use these:
http://www.cplusplus...clibrary/cmath/
You should use it when you find the difference


You should have two methods.
Your first one, main, should have a while loop
Second one should have the (1+1/n)n part

Ok so in main...
create two double values.
One of them will be holding the value before you send it off, and the second should hold the value you send off (otherwise known as n in your post)
Then have a do-while loop. The while part should be while( abs(initialnum - secondvalue) < 1e-8) (use math.h here for the 1e-8)
In the do-while loop, you should...
make your intialvalue = secondvalue and then have your (secondvalue * 2) be sent to the other method and make the return value of the method equal to secondvalue
so now you've updated intialvalue with the new initialvalue and secondvalue should be your new value

outside of the do-while loop, print out second value.

in your second method, heading should be

double methodname (double somevariablename)
and in this method, it should be like
variable = (1 + (1/variable)) * variable ;
// same thing as (1+1/n)n
then return variable



I can do it for you, but if learning is better.

AND IF SOMEONE FUCKING 'ED ME, IM GOING TO SUICIDEE

EDIT: its the approximation cuz you can't get teh EXACT value of e
and parameter is this part (double &somevariablename)
so I could say that somevariablename is a parameter of the method methodname

Junsu covered most of it, but I'll try to clarify:
(You should already know what a class is, at least I hope so)
In your class, you should have two things: a main and a method

The main is what runs when you actually compile the program. So in the main, you should actually write the code to loop through and call your method on each iteration.
The method is like a function in algebra. You pass it a parameter, and it processes stuff using the variable (well technically, you can pass it nothing if you want).
In your case, your method should take in the variable n (which is an int), and return (1+1/n)^n.

Junsu covered the example code pretty well.
If you're having trouble, you should ask your teacher for help.
