I've been looking for a tutorial like this for weeks. You seem to be the only guy ON INTERNET who doesn't take anything for granted and actually explains every single aspect of the programming language with knowledge and clarity. Most people don't understand that even the smallest insignificant detail could be very confusing for a neophyte if they don't explain what it does and why it behaves that way. Thanks for going so in depth on each topic!

@@programmingwithmosh The only aspect I'd like to point out is if you could explain a little simpler than that, because you go into defining the beginning lines of code in a technical manner and I could not understand it all. Can you explain a little more simpler why do we have the beginning code and what is it used for and if it needs any changing? Thank you and aside from that, your video is great! :)

[@CalebDiT]

Wow, finally somebody who knows how to pronounce "pi" correctly! OK, that's a useless comment for your great contribution, here, Mr. Mosh. I will try to add at least one useful thing, then: In the new C# 6, the string placeholders can be written like this, which can be a little cleaner: Console.WriteLine($"{byte.MinValue} {byte.MaxValue}") Cf. the example at 39:35. Thanks for sharing your time and knowledge!

[@ScooterFXRS]

Pie and pi are two words that are pronounced in the same manner but are spelled differently and have different meanings, which makes them homophones. It is correct if he was speaking a language where this is supported. The word pie is assumed to be connected to the Latin word pia meaning pastry or pie, and the Old English piehus meaning bakery. Greek classic spanakopita (spinach pie). Hence it became a literal translation.

[@Nightcore_Paradise]

How is it now?

[@Orken1]

Hey! Love the tutorial, will definitely purchase the full course. Was just wondering though, isn't it easier (generally speaking) to read the code if "correct" type is used instead of "var"? Personally i find it easier and faster to read the code with strings named string, ints named int etc. Thoughts?

[@ToskersCorner]

Depends. As a beginner it probably is good to not use var especially when working with unfamiliar types(That's just from my experience). However as you progress, it becomes much quicker and even easier to read when using var instead. I only think specifying types is good when you are still familiarizing yourself with them. Generally the right side of the operator will give you a answer to what type the var is.

[@ToskersCorner]

I guess all I was really trying to say is as a beginner I found it helpful in regards to learning. You do not always need to know the type, but I think by specifying type it helps you stay aware of what types are and how to use specific ones and how they are different. Of course this is not necessary for anyone near intermediate, but I think it could be helpful in regards to the perspective of a day 1 beginner. In a nutshell I think association is good for learning. Using var is good when you are beyond that level of learning. I'm just speaking from what I feel helped me as a beginner. Other people may be different.
