I'm writing a header file by C++ in VScode, but VScode show me:
'iostream' file not found
In cpp file, it never happens. I think I should install all it need. And I never meet it before.So I don't know how to do with it.
Ok, I try to give more details.
I use vscode to write code. In last codes, I just used '.cpp' files, so I haven't get an error report. But in this time, I try to write my header file as above, vscode tell me:iostream' file not found. I can't correct it. So I ask someone for help.
You can try recognize the compiler. Open command palette CTRL+SHIFT+P, type C/C++: Edit Configurations (UI) and open, then choose your compiler path, for instance, C:/MinGW/bin/g++.
