Hi. I'm a newbie with Salesforce and I've created a Developer Account for a while and now I want to work with Salesforce DX. So I think I have to Register for a Dev Hub Org on this site: 
https://developer.salesforce.com/promotions/orgs/dx-signup
the problem is that it doesn't ask me any password but when I want to go to the link that I've received and login, it needs a password. so I cannot login anymore. What should I do? 
I just want to work and get familiar with the Salesforce DX features. 
If somebody has a good reference for creating an account (Get your own 30-day Dev Hub Trial Org), please share it. 

Hello, I'm a newbie to the Salesforce platform. 
Can anybody say why we can not use "int" in "for" clause and we have to use Integer in it?
for example 
for (Integer i = 0 ; i < 200; i++) { ... } is correct but 
for (Integer i = 0 ; i < 200; i++) { ... }  is wrong.
