Red underlining on iostream (C++ Ext. Installed, compiler path correct)

[DigitalGreenTea]

Hi all,

I’m a complete beginner to C++ and programming and I followed the Unreal C++ Udemy course up until lecture 18.

I have a red underlining on #include iostream despite me installing the c++ extension. The complier also gets found and the path in the .json file is correct.

While compiling, I do get the warning “C4530: The code uses C++ exception handling, but [/EHsc] wasn’t included in the compiler options.” If compile with cl triplex.cpp /Ehsc, it works without issue.

I have been fighting this issue for hours now. Please help me.

Could you show screenshots of the json and the path to cl?

Here’s how the full path looks like. For some reason, it’s not working.

I did install the C++ modules during the Visual Studio Installation and I also downloaded the C++ expansion by Microsoft on Visual Studio Code…

And to be clear you can compile and run the program successfully?

@DigitalGreenTea

cl triplex.cpp /Ehsc

Yes, I was able to compile using cl triplex.cpp /Ehsc and run the programm afterwards. The red underlinings are still present though… I’m guessing I can continue the course without any issues?

You should be able to. Not sure why IntelliSense isn’t working for you though sorry.
