I've looked at multiple tutorials + the book i'm reading and i still don't full understand what namespaces are and what they're used for.....


From my understanding, namespaces are used as a container to hold names for classes, that might use the same name? idk.....




Would appreciate if someone could go very indepth about what they are and what they're for.... the tutorial and book i'm using didn't say much

Its not a big deal, here we go:



so, as u can see the namespace (as the name namespace itself says) declared a special room for variable names
you can declare multiple namespaces and use them by "using namespace ferf-one" (whole room) or "ferf-one::jsp" (single variable)
namespaces can be used in complex structures as well

hmmm thanks, that bettered my understanding a bit



so they're basically to hold anything with the same name, variables, classes, etc....Sounds kind of dumb, why not just use a different name

first of all im new to c++ as well, so maybe there are mistakes in my knowledge.

till now i used only one time activ namespaces in a project. but normally you use it in a indirect way.
nearly every method that you callup in your projects use namespaces. if they wont you could have a problem...

for example your using a method to give something out on a display and this method use the variable "n"

"n" is used in many programs and these method would overwrite your variable "n" if it wouldnt use a another namespace.

you're absolutely right. before you write any code, you should call the thousands of C# developers out there and ask what their classes are named so that you can pick a different name.

i was going to tell you what they were used for, had it all typed out

but then i realized just how stupid this question really is

This is one of the most common issues beginners learning .NET run into. This is far from a stupid question.

I will say it's quite a lazy question though. They're literally hundreds of resources online that can better answer this question.

@OP If i can give you one piece of advise, It's... Google is your best friend when it comes to learning.

On Topic - I personally hate learning from books. I'm a visual learner and i prefer learning from example. With that said, here is a site that has links to 200 SHORT (youtube) C# tutorials for entry level. Video #19 touches on Namespaces but i would suggest you start watching from #1.
