Just a question

[Naughty Albatross]

I am about to download and install Visual C++ 2015 community. My computer only has 1Gb RAM. Is it sufficent?

Also, is it flexible enough to support C++11 and C++14?

I hear that modern C++ compliers nowadays comsume lots of computer memory these days. Is it true?

You should be fine. Just idling (Not compiling, debugging, etc.) I am running it around 120MB for a single instance of VS. As for debugging I am running at around 200MB give or take for a smallish application.

Also, is it flexible enough to support C++11 and C++14?

You shouldn't have any troubles using C++11 and C++14 features with MSVC++ 2015. There is a few language features that aren't implemented for C++14* but I personally don't find that an issue. They also have quite a few features of C++17 implemented (And some Tech Specs like beta support for Modules).

I have no idea, though I don't think it would really make that much of a difference... There really should be no reason to not use a modern compiler (Unless for some reason you need to target a specific compiler version).

I really recommend you download the full ISO, not the webinstaller.

Mount the ISO with virtual drive software and do a custom install. Visual C++ is not installed when you do a default installation.

If you don't have virtual drive software you can get Virtual CloneDrive (it's free):

Why do I recommend the ISO? Easier to make changes to your VS installation without tying up your internet connection, and it installs so much quicker from start to finish with the ISO.

Never was true, isn't true now.

A compiler is different, one part of many, than an Integrated Development Environment (IDE). Visual Studio is an IDE.

An IDE provides a single interface -- simplified explanation to follow -- for creating, editing, compiling and debugging source code.

You might want to look at this link, it shows many of the details of compiling source code. Details using an IDE hides from you:
