Answer 1

When you use C libraries in C++, include them with 'c' prefix like:
#include <cmath>
Btw you included iostream, but use cstdio (you are using printf instead of cout for some reason)

What do you mean by "amount" of series? Sum?
You can't actually make it to infinity, because it will work forever. You can set a limit and check if the n-th element is less than the limit, then break out of the loop.
I would use do-while loop to calculate sum of the infinite series with the rule I mentioned

Answer 2

Your line number 10 you decleared x variable after this line
double f1 = -log(x - 1 / x)
Here your x is undefined and undeclared for this expression. your variables are not decleared in particular scope

Answer 3

i use printf and math.h cause nothing change in comparing with C++ lib, yes i wanna get sum , but i am not fully aware how to do it ,probably [0,5] is a limit

Answer 4

A.S i know that, i just briefly wrote a code

Answer 5

You can use printf, but use correct header files, as you are writing your code as C++. These languages are not the same.
