Question
Using a `for` loop, compute the following alternating sum:

\[ 1 - \frac{1}{2} + \frac{1}{3} - \frac{1}{4} + \ldots + \frac{(-1)^{(n+1)}}{n} \]

where \( n \) is a positive integer from a user. Define `sum` to be a `double` variable.

**Sample output 1:**

Type a positive integer n: 4  
Sum = 0.583333  

**Sample output 2:**

Type a positive integer n: 1  
Sum = 1
