Yes it is, none of the Visual Stdio editions have C mentioned, but it is included with the C++ compiler (you therefore need to look under C++). The main difference between using C and C++ is the naming system (i.e. using .c and not .cpp).

You do have to be careful not to create a C++ project and rename it to C though, that does not work.

Coding C from the command line:

Much like you can use gcc on Linux (or if you have MinGW installed) Visual Studio has a command to be used from command prompt (it must be the Visual Studio Developer Command Prompt though). As mentioned in the other answer you can use cl to compile your c file (make sure it is named .c)

Example:

cl myfile.c

Or to check all the accepted commands:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community>cl
Microsoft (R) C/C++ Optimizing Compiler Version 19.16.27030.1 for x86
Copyright (C) Microsoft Corporation.  All rights reserved.

usage: cl [ option... ] filename... [ /link linkoption... ]

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community>

Coding C from the IDE:

Without doubt one of the best features of Visual Studio is the convenient IDE.

Although it takes more configuring, you get bonuses such as basic debugging before compiling (for example if you forget a ;)

To create a C project do the following:

Start a new project, go under C++ and select Empty Project, enter the Name of your project and the Location you want it to install to, then click Ok. Now wait for the project to be created.

Next under Solutions Explorer right click Source Files, select Add then New Item. You should see something like this:

Rename Source.cpp to include a .c extension (Source.c for example). Select the location you want to keep it in, I would recommend always keeping it within the project folder itself (in this case C:\Users\Simon\Desktop\Learn\My First C Code)

It should open up the .c file, ready to be modified. Visual Studio can now be used as normal, happy coding!

Yes, you can:

You can create a C-language project by using C++ project templates. In the generated project, locate files that have a .cpp file name extension and change it to .c. Then, on the Project Properties page for the project (not for the solution), expand Configuration Properties, C/C++ and select Advanced. Change the Compile As setting to Compile as C Code (/TC).
