I'm using VS code as my IDE fr a small C++ project, and I'm using the terminal to compile it using G++ (I know I could set up a build environment but I find it easier for now).
g++ *.cpp -o main
Problem is, when I compile a bunch of files, and the compiler tell me that something is wrong, I go back to the editor, apply the changes, and then recompile, but the terminal shell (Powershell in my case), still "sees" the old file.
Only closing the terminal and reopening a new shell solves the issue.
This is very annoying, since I find VS code a great IDE.

So I just got into using VS Code. I am currently working with C++ and I am using Mingw as my compiler. So far I have been using the terminal at the bottom of VS Code to compile and run like this:
g++ program.cpp then doing ./program.exe
The process of using the terminal at the bottom is time consuming especially when I need to compile and run code frequently. This is also annoying when creating classes when you have to compile multiple files into .o extensions etc.
Can anyone help with this process? Am I doing something wrong, should there be an easier way? Maybe a makefile?
Thanks!
If you want to compile and run C++ code in visual studio code(Vs-code) in windows. This include following steps.
Download Visual studio code.
Go on Add extension Type C++ and install "C/C++" by Microsoft.
Go to Visual Code studio docs for "C++" OR https://code.visualstudio.com/docs/languages/cpp
Install MinGW-x64 vis MSYS2 website and run this on shell "pacman -S --needed base-devel mingw-w64-x86_64-toolchain"
Then go to windows setting and look for Edit environment variables for your account. Then in advance settings >> Environment Variable.
In "system variable" choose path and edit it and add a new path.
You can find a new path in your directory where you have installed the MinGW-x64. you might find it in C:\msys64\mingw64\bin. or where ever you have installed it.
When you have added the new path then go to any shell/cmd and Type g++ --version
if you get the version then you have succeded.
If you find something like command not recognized then please check where you have done wrong or skipped any step.
Otherwise startover.

I am programming in C in Visual Studio Code, but I can't compile, as VSC only offers three compilers built in - Node.js, C# Mono, and Extension development. After a little bit of digging I came across the Visual Studio Marketplace. This seemed like the right sort of thing, but only four uncommon languages were there.
I can only assume that C debugging support is built in, I just can't find it or I am going the wrong way about doing it. I attempted to create a new launch.json (the manifest that seems to hold the compiling/debugging settings for each file) and manually entering the GCC binaries that I have, but that didn't end up working. I'm currently stuck manually compiling the C source file I am working on through command prompt.
Would really help if someone could point me in the right direction on what to do.
tl;dr - Help from anyone debugging C in Visual Studio Code
Windows 8, if that matters
Cheers!
Caution
A friendly reminder: The following tutorial is for Linux user instead of Windows
Tutorial
If you want to debug your c++ code with GDB
You can read this ( Debugging your code ) article from Visual Studio Code official website.
Step 1: Compilation
You need to set up task.json for compilation of your cpp file
or simply type in the following command in the command window
g++ -g file.cpp -o file.exe
to generate a debuggable .exe file
Step 2: Set up the launch.json file
To enable debugging, you will need to generate a launch.json file
follow the launch.json example or google others
Step 3: Press (Ctrl+F5) to start compiling
this launch.json file will launch the configuration when you press the shortcut (Ctrl+F5)
Enjoy it!
ps. For those who want to set up tasks.json, you can read this from vscode official (-> TypeScript Hello World)
Press Ctrl + Shift + P to pull up the Command Pallette, and Type ext install cpptools. It will install everything you need to debug C and C++.
Debugging in VS code is very complete, but if you just need to compile and run:
https://code.visualstudio.com/docs/languages/cpp
Look in the debugging section, and it will explain everything.
There is a much easier way to compile and run C code using GCC, no configuration needed:
Install the Code Runner Extension
Open your C code file in Text Editor, then use shortcut Ctrl+Alt+N, or press F1 and then select/type Run Code, or right click the Text Editor and then click Run Code in context menu, the code will be compiled and run, and the output will be shown in the Output Window.
Moreover you could update the config in settings.json using different C compilers as you want, the default config for C is as below:
"code-runner.executorMap": {
"c": "gcc $fullFileName && ./a.out"
}
For Windows:
Install MinGW or Dev C++
Open Environment Variables
In System Variable select Path -> Edit -> New
Copy this C:\Program Files (x86)\Dev-Cpp\MinGW64\bin to the New window.
(If you have MinGW installed copy its /bin path).
To check if you have added it successfully: Open CMD -> Type "gcc" and it should return:
gcc: fatal error: no input files compilation terminated.
Install C/C++ for Visual Studio Code && C/C++ Compile Run || Code Runner
If you installed only C/C++ Compile Run extension you can compile your program using F6/F7
If you installed the second extension you can compile your program using the button in the top bar.

Just wanted to add that if you want to debug stuff, you should compile with debug information before you debug, otherwise the debugger won't work. So, in g++ you need to do g++ -g source.cpp. The -g flag means that the compiler will insert debugging information into your executable, so that you can run gdb on it.
You need to install C compiler, C/C++ extension, configure launch.json and tasks.json to be able to debug C code.
This article would guide you how to do it: https://medium.com/#jerrygoyal/run-debug-intellisense-c-c-in-vscode-within-5-minutes-3ed956e059d6
EDIT: As of ~March 2016, Microsoft offers a C/C++ extension for Visual Studio Code and therefor the answer I originally gave is no longer valid.
Visual Studio Code doesn't support C/C++ very well. As such it doesn't >naturally support gcc or gdb within the Visual Studio Code application.
The most it will do is syntax highlighting, the advanced features like >intellisense aren't supported with C. You can still compile and debug code >that you wrote in VSC, but you'll need to do that outside the program itself.
The title really says quite a bit, but let me give some context.
I am trying to work on coding without relying on an IDE like Visual Studio, so please don't suggest that I simply use an IDE to fix my problems.
Additionally, I will not accept suggestions that I use something other than G++ to compile my code with. That's not a solution to my problem, that's an alternative path completely, and not one I wish to use.
So far, I have installed MinGW-64, and am using g++64 to compile my software. For some reason, my code compiles flawlessly, but upon execution, Windows 10 tells me "This app can't run on your PC". Upon inspecting the Event Viewer, the error is that the program "cannot start or run due to incompatibility with 64-bit Windows." That doesn't make much sense to me, considering I'm compiling it with a 64-bit compiler. However, I am reasonably new to programming and to using the GNU toolchain, so perhaps I'm doing something incorrectly.
Here is my current command to compile from command line:
g++64 -c -Ic:\code\cpp\projects\git_test\include opengl_test.cpp -o opengl_test.exe
Perhaps there is something with OpenGL, FreeGLUT or GLEW that is causing the issue?
EDIT 1:
I took the suggestion to remove the -c option, and now I'm getting a lot of undefined reference errors. I tried to add the libraries, but it doesn't appear to work, even though the files are clearly in the folder I've added.
Here is my new command to compile:
g++64 -LC:\code\cpp\projects\git_test\lib -IC:\code\cpp\projects\git_test\include -lfreeglut -lglew32 -lglew32s opengl_test.cpp -o opengl_test.exe
I have just started to get experiment with C++ on my MacBook Pro, and am very new to it all. Through research, a few different people have suggested to use TextWrangler for writing the code. I have put together some of the code that the beginning of a tutorial has given me, but I am now unsure how to run it through TextWrangler. I know that you are supposed to compile it first, but that is mostly where I'm stuck. I have downloaded Xcode so I have gcc, but I don't know where to go from there. And after I have compiled it, is there a simple way to run the file? Like I said, I am very new to all of this and may be looking at it in the wrong way.
TextWrangler is only a text editor, you still need a compiler to compile your code and then you need to run your code.
Xcode (which is an IDE) does all that for you so the confusion is understandable.
for now opening a terminal and doing g++ filename.cpp to compile and ./a.out to run your program will get you going. But you really have to learn to use a IDE or how to write a makefile.
I've been programming on windows for about three months now and when my computer finally died I bought a mac. I'm really happy with it except I can't figure out how to run my c++ programs.
On windows it would open up in command prompt so I figured it would do the same thing except with terminal.
After I write my programs (in Xcode) I can compile them and it'll tell me if there are syntax errors but the run and run related buttons are all Grey and unusable.
It's incredibly annoying that I can't see how the program that I put 4 hours into runs and even more annoying that I don't know if I've made a runtime error. Someone please help.
Thank you very much, James
Assuming that you're trying to write a program that you interact with on the command line, you want to create a "Command Line Tool" project, found under "Application" in the Mac OS X section of the New Project dialog. Choose "C++ stdc++" from the "Type" dropdown, as well. This will give you a main.cpp that should look familiar to you, with a "Hello, World!" sample.
Note that when you Run this program, it might appear to do nothing - You need to open the Console (from the Run menu, or shift+command+R) to see your output.
Xcode deals in projects. If you're just opening the source file, there is no project. Create a project with the files in it and Xcode should let you run it.
Alternately, you can just use G++ on the command line to compile your files and run the resulting executable there.
Try compiling from the terminal as stated above. The a.out file should be created, and should run as long as Xcode has been installed. It should work fine from the terminal, and point out any errors in the compiler's output.
To runs the a.out file, ensure you are in the files directory in terminal and type ./a.out
