Welcome to Stack Overflow! Questions seeking debugging help ("why isn't this code working?") must 
include the desired behavior, a specific problem or error and the shortest code necessary to 
reproduce it in the question itself. Questions without a clear problem statement are not useful 
to other readers. See: [How to create a Minimal, Complete, and Verifiable example](https://stackoverflow.com/help/mcve).

Welcome to Stack Overflow! Questions asking us to recommend or find a book, tool, software library, 
tutorial or other off-site resource are off-topic for Stack Overflow as they tend to attract 
opinionated answers and spam. Instead, [describe the problem](http://meta.stackoverflow.com/questions/254393) 
and what has been done so far to solve it.

Please clarify your specific problem or add additional details to highlight exactly what you need. 
As it's currently written, it’s hard to tell exactly what you're asking. See the 
[How to Ask page](https://stackoverflow.com/help/how-to-ask) for help clarifying this question.

Welcome to Stack Overflow! This is not a website where people write code for you so that you don't have
to. If you need help debugging code that you have written, you must post a 
[Minimal, Complete, and Verifiable example](https://stackoverflow.com/help/mcve) and explain the specific problem
with your code.

Welcome to Stack Overflow! Please ensure that you are compiling with warnings enabled (refer to the manual of your 
particular compiler for instructions). A good compiler can catch many common errors for you, including the one in 
this question, but you need to ensure that this functionality is enabled.

Links to external resources are encouraged, but please add context around the link so your fellow users will have 
some idea what it is and why it’s there. Always quote the most relevant part of an important link, in case the
