Hi everyone. I have experience with prog.languges such as C(c++,c#), Java and a little with python. My question is how to create a 2d array in ruby. I`ve searched around but did not found any normal solution... Also i would like to ask a few things like:
1. What does the self. does
2. What does super()
3. What is the purpose of Class exmaple < ex - ( the <ex ?????)

I read about the language , but it seems messy to me even after looking at some examples.

self is a pointer to the current object, used in class definitions to call a member function of that class instead of a global function by that same name, or access a member variable instead of creating/reading from/writing to a local variable by that name.

super() invokes a specific class method implemented by that particular class' parent class. For example, if class A has a function named foo(), class B inherits from A and overrides foo(), then class B can use super() to invoke A.foo() instead of B.foo() as would be the default.
