In atom, when I write any code incorrectly I can view the errors immediately because the file is being scanned by a plugin.
I have the vs code plugin for c/c++ but I do not see this option to display errors. Is this available and I am just failing with my google skills? Or is this not an option with vs code?
The VSCode plugin for C++ does not support "intellisense" at the moment.
It supports debugging and some basic symbol parsing (with code completion) but it doesn't parse your code using a compiler.

so I recently got started with vscode and working with the c++ project when I noticed that some of the errors aren't displaying. Also, the program would run fine on vscode but when used it on repl.it it would show some critical errors like "signal: Aborted (core dumped)" and it would tell me at which line it encountered that problem.
Looking at vscode however it seems to me it doesn't detect subtle errors such as when I have a function that would return a string and I purposely return 0 instead of a string it still considers it a valid operation. I don't know if the issue is the IntelliSense or some error-checking aspects, but one thing for certain I know visual studio would show this with a warning sign that would appear on the number line.
I do have the squiggly lines enabled for errors and it does show errors if I have some keyword typed incorrectly. What I want to know is where the c++ would fail to run and tell me before the run, or even during runtime.

VSCode is pretty intelligent, and in theory it should be able to have all the IntelliSense that those other IDEs have. However, that does not come out of the box. What you need to do it install some extensions specific to the programming / scripting languages that you work with. For example, for C++ you can download C/C++ extension developed by Microsoft.
After installing the needed extensions please read some documentation and tweak them as needed.
Your IntelliSense issues will be solved.
I've figured out that it wasn't displaying the crash errors because my installation of msvc was flawed. I downloaded msvc again and used the Pacman commands to install all the necessary files and now my crash errors show. However, some syntax errors still don't show like int main {... without a closing curly brace. This code still runs, and the error is picked up during the run time. I would've expected the error to be highlighted before the run.
I want to build a C++ code but it errors. When I check the error message it's related with .NET. I have C# extensions but this isn't C# and I want to change this to g++ for C++ projects. I have g++ installed and added to path however I don't know how can I configure it to build with that for C++ codes.
Edit: I marked the answer as a solution but I also found an easier way for me:
https://code.visualstudio.com/docs/cpp/config-msvc
cl.exe basically.
One option (probably not the one you want to) is to build it from integrated terminal.
You can download c/c++ extension along with the cmake tools extension to have buttons for build/run configuration.
I can't compile any c++ code in VS Code. Whenever I try, it throws me to the settings.json file, where I see this:
{
"python.defaultInterpreterPath": "C:\\Users\\Pavel Sankin\\AppData\\Local\\Microsoft\\WindowsApps\\python.exe",
"python.pythonPath": "C:\\Users\\Pavel Sankin\\Anaconda3"
}
and nothing else. I did install the standard C/C++ extension and tried checking out the official website for help, but there seem to be other things there. VS Code doesn't throw any errors, it just opens this file whenever I try to compile any piece of C++ code.
Any help will be much appreciated.
Have you had this problems before?
Have you install the microsoft C++ compiler toolset? (other compiler works fine too; check VS docs)
Did you open VSCode using the Developer Command Prompt?
Also check this and follow the guide.
This is code for a template which i am trying to inherit. This is not giving any error in programme but what these warning are trying to suggest
Basically, VSCode uses linters tools to analyze code errors. Linters can show the errors and warnings you see there.
If the installed linter doesn't support the syntax/wasn't written for this syntax, it will throw an error/warning. It's common to see those, and you can force-ignore them on VSCode Settings (More info here).
You can also change and set the linter by yourself on settings, or you can install an extension that does that for you.
I'm mostly using VSCode. I have two questions:
In the case of having a compiler error, VSCode warns you while you are writing the code (before you compile/run your program.) How I can do this?
How I can have the environment so that when I click on run button it compiles, runs and shows me the output in the terminal section?
Maybe this extension could be of help: C/C++ Advanced Lint
Install Microsoft's C/C++ extension and have a look at the documentation. Especially the topic "Create a build task" should be of interest for you (after you've done all the prerequisites steps.
