Hello, so I am new to coding and wanted to use VS Code to code in C++, so I installed it, installed C/C++ IntelliSense v0.12.4 and followed instructions on the VS Code website to make a c_cpp_properties.json file and copied the code into it like they said. When I open my .cpp project that I had made in notepad++, I get the error:
"#include errors detected. Please update your includePath. IntelliSense features for this translation unit (directory\file.cpp) will be provided by the Tag Parser. (9, 1)
cannot open source file "iostream" (9, 1)"

My .cpp code
`#include

using namespace std;

int main()
{
string firstName, lastName;
double hourRate, numHours;

    cout << "+----------------------------------------+" << endl;
    cout << " Your first name and last name: ";
    cin >> firstName >> lastName;
    cout << " Your hourly rate: ";
    cin >> hourRate;
    cout << " Number of hours worked last week: ";
    cin >> numHours;
    cout << endl;
    
    double regPay, overTPay, gPay, socSec, med, netPay;
    if (numHours <= 40)
    {
        regPay = hourRate * numHours;
        gPay = regPay;
        overTPay = 0;
    }
        else
        {
            double oTHours;
            oTHours = numHours - 40;
            regPay = hourRate * (numHours - (numHours - 40));
            overTPay = (hourRate * 1.5) * oTHours;
            gPay = regPay + overTPay;
        }
    socSec = gPay * 0.062;
    med = gPay * 0.0145;
    netPay = gPay - (socSec + med);
    cout << "+----------------------------------------+" << endl << endl;
    cout << " Pay Stub\n" << " Regular pay  $" << regPay << endl;
    cout << " Overtime pay $" << overTPay << endl;
    cout << " Gross pay    $" << gPay << endl;
    cout << " Social Sec.  $" << socSec << endl;
    cout << " Medicare     $" << med << endl;
    cout << " Net Pay      $" << netPay << endl << endl;
    cout << "+----------------------------------------+" << endl << endl;
    cout << " Pay to: " << firstName << " " << lastName << endl;
    cout << " Total Pay: $" << netPay << endl << "\t\t\t   ";
    cout << "Signed: P inc." << endl;
    cout << "+----------------------------------------+" << endl;
    
    return 0;
}`

Your includePath only has ${workspaceRoot}. You need to add the path to your system directories. If you're using MinGW, see https://github.com/Microsoft/vscode-cpptools/blob/master/Documentation/LanguageServer/MinGW.md .

If you are using Linux you have to add the path /usr/include/linux

I had same issue on windows, after I add the "C:\\cygwin64\\lib\\gcc\\x86_64-pc-cygwin\\6.4.0\\include\\c++" at includePath, I got this error: cannot open source file "bits/c++config.h" (dependency of "iostream")

What does gcc tell you the include path should be? Run this command and make sure all of the paths printed out are listed in your c_cpp_properties.json: gcc -v -E -x c++ -

@sean-mcmanus after adding the code from the link you gave it still complains, I didn't add "C_Cpp.intelliSenseEngine": "Default" to my settings.json file because I have no clue where it is. Anyway, this is the new error I am getting.
"#include errors detected. Please update your includePath. IntelliSense features for this translation unit (E:\\program.cpp) will be provided by the Tag Parser. (9, 1) cannot open source file "iostream" (9, 1)"

@NikoGP Go to File->Preferences->Settings and search for "intelliSenseEngine" to find the setting. You have "Default" set already though. Did you run the gcc command @bobbrow mentioned? Can you provide your updated c_cpp_properties.json? You basically need to find where your iostream header is getting pulled from by your compiler and add the path to the includePath setting (and make sure the defines are correct). Does Go to Definition work on the header file? If so, that means the iostream file was found via a recursive search of your browse.path setting.

Here is my current c_cpp_properties.json file, when I hover over the "{" before configurations Win32 it says "missing property "name""
Also, I installed cygwin before installing MingW, I'm not sure if that messes anything up or not

I reformatted your comment. There is a "configurations" element inside your "configurations" which is invalid syntax for the c_cpp_properties.json file. Fix it like below:

Even using the code above @bobbrow VSC still complains and says;
"#include errors detected. Please update your includePath. IntelliSense features for this translation unit (E:\program.cpp) will be provided by the Tag Parser. (9, 1) cannot open source file "iostream" (9, 1)"

What version of MinGW are you using? In your first post, it looked like you had 6.3.0 in your include path. In your most recent post, it looked like you pasted in include paths for 5.3.0 from our MinGW page.

Okay, I think that my problem lies in the fact that I had installed cygwin prior to MingW, and then I incorrectly installed the required packages for MingW to properly function.
Is there somewhere that I can find what packages I need to install for VS Code to work properly with MingW?

I am also having the issue seen by @NikoGP with my Intellisense after upgrading to v0.13.0. When I turned on the "Default" setting on the Intellisense engine, I keep receiving an iostream include path error (see attached files). I'm running MacOS 10.12.6, and have updated the LLVM engine as well.

The error under the iostream include is:
#include errors detected. Please update your includePath. IntelliSense features for this translation unit /pathToProgram/) will be provided by the Tag Parser.
cannot open source file "wchar.h" (dependency of "iostream")

Simple "Hello World" example showing the error:
helloworld_example

My c_pp_properties.json file:
c_pp_properties

@smithalexk, for me, this file resides in /usr/include. What does clang -Wp,-v -E -xc -x c++ /dev/null show as your include path? The "includePath" in your c_cpp_properties.json file should match that.

Note to MacOS users, if you are using gcc version 8.1.0 (for example) from Homebrew, your MacOS configuration should look like this:

{
    "name": "Mac",
    "browse": {
        "path": [
            "${workspaceRoot}"
        ],
        "limitSymbolsToIncludedHeaders": true
     },
     "includePath": [
         "${workspaceRoot}/**",
         "/usr/local/Cellar/gcc/8.1.0/include/c++/8.1.0",
         "/usr/local/Cellar/gcc/8.1.0/include/c++/8.1.0/x86_64-apple-darwin16.7.0"
     ],
     "defines": [],
     "compilerPath": "/usr/local/Cellar/gcc/8.1.0/bin/gcc-8",
     "cStandard": "c11",
     "cppStandard": "c++17",
     "intelliSenseMode": "clang-x64"
}

Very simple. You do not need to include headers from XCode. Do not set compilerPath to /usr/local/bin/gcc-8, as this is a symbolic link that may mess up IntelliSense. If you are still having issues as I did, set the following user setting in settings.json as others have to get around a recent issue: "C_Cpp.intelliSenseEngine": "Tag Parser",

What include files needed to run my code using cl.exe from MSVS 2015?

I've included these folders in c_cpp_properties.json:

"C:/Program Files (x86)/Windows Kits/8.1/Include/shared",
"D:/Program Files (x86)/Microsoft Visual Studio/2017Community/VC/include",
"D:/Program Files (x86)/Microsoft Visual Studio/2017/BuildTools/*",
"D:/Program Files (x86)/Microsoft Visual Studio/2017/BuildTools/VC/Tools/MSVC/14.13.26128/include",
"D:/Program Files (x86)/Windows Kits/10/Include/10.0.10240.0/ucrt",
"D:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Tools/MSVC/14.13.26128/include",
"D:/Program Files (x86)/Mirucrosoft Visual Studio/2017/Community/VC/Tools/MSVC/14.13.26128/atlmfc/include",
"D:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Tools/MSVC/14.13.26128/crt/src/x64",

But still I get an error while try to build:

> Executing task: & 'D:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Tools/MSVC/14.13.26128/bin/Hostx64/x64/cl.exe' 'h:\C++ Programs\ExBox01.cpp' <

@adam-erickson There's a crashing bug with gcc 8.1 you may be hitting (#2328 ) -- our latest insider release has the fix: https://github.com/Microsoft/vscode-cpptools/releases/tag/v0.17.8-insiders .

@prdas31 Our extension doesn't currently support any build features -- the c_cpp_properties.json is for the IntelliSense feature and not actual compiling. For building with MSVS 2015, you may need to build from the developer command prompt that ships with VS.

Thanks a lot for the clarification and suggestion. I now use build files to include the paths like this:

if exist "D:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Auxiliary\Build\vcvarsall.bat" (
    call "D:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Auxiliary\Build\vcvarsall.bat" x64
) else (
    call "D:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat" x64
)

This idea is taken from an VSCODE extension called Easy C/C++ Project.

Thanks.
