What language of C family does AGS scripting language resemble?

Hello, AGS community 

1) What of the three programming languages is AGS custom scripting language more similar to - C, C++ or C#?

2) Will learning C, C++ or C# help in adding more stuff to AGS game scripts like other genre mechanics?

Thank you!

C and C# mostly.
The basics of functional programming are from C, and the script commands were done in C-style in the old days.
The managed structs, managed pointers, attributes are resembling C#.

Learning other languages might also help, because many concepts are shared between languages even if their syntaxes differ. Besides learning a language on its own, it's also important to learn writing algorithms and structuring the code.

Hello, dear Crimson Wizard.

C and C# mostly.

So, does it mean scripting languages in say AGS and Unity games are not that different from each other? 

Besides learning a language on its own, it's also important to learn writing algorithms and structuring the code.

What's the most right (quickest?) way to learn writing algorithms and structuring the code?

Thanks a lot!
