ok first of all im new at this and im beginning to learn programming so from what i understand this is a forum for and helping others learning, i would appreciate some helpfull advice from people that know and not this stupid comment criticizing the work of a learning student. 

The problem is that you have this over-arching problem, that you need to split into smaller problems.
I'm not going to give you the code to do it, but here is a general overview of what you probably need to do:
When you ask the user if they want to change their security pin (I'm not sure exactly how you do it, I'm sorry I don't speak Spanish), you just need to prompt the user to input a number for example "1234", then convert that number to an integer and store it in the variable you're using for the security pin.
 
If you wanted to go a step further you could probably have a collection of names and their associated pins, credit card numbers, etc. in a JSON file (or a text file, but that would mean you would have to have an arbitrary formatting for the text file, which wouldn't be very expandable, so they don't have to enter their details every time they run the program, you could just prompt them with a "Are you new [Y/N] > ", or something similar.
 
I hope this broke the problem down a little bit so you could understand it better, good luck with your project!

Just buy a bottle of rubbing alcohol and a microfiber cloth or two.

great stuff guys ! very nice, i personally have the corsair strafe rgb keyboard with cherry mx brown switches, they obviously are not that loud as the blue switches but they are fairly loud and i love it ! and the lighting effects... they are just amazing.

Way to put that into perspective.  

Not a heck of a lot but for the price of a burger and fries I'd have to choose the 3200.

It won't impact most gaming much.  A bump in frames here and there, but for $12 more, you might as well get the 3200 MHz. 

Close to none in a Dedicated GPU Scenario,on the other hand if you use a APU it makes a difference there
 
Also in some games you could benefit from higher clocked ram

1. What case do you have?
2. I find the masterair making quite overpriced...when you can get better preforming air coolers for less...(or that's the impression I got from LTT's review).
3. If you don't care about looks, maybe a noctua tower style cooler might be better?
4. The h100i preforms decently while being around the same price and looking cleaner (in my opinion) so it's your call? :D

ASUS makes better motherboards, but if you want to go MSI because of looks then there really isn't a huge difference.

+1 to the MSI

I am an MSI fan myself and only build with MSI if I have a say in the build. +1 MSI. With that said, Here are some great reviews of the boards from HardOCP.com
