Hi, I found that the autosuggestion provided by VS code is not working after I installed and enabled this C/C++ extension. (Only c or cpp files have this problem)
I have changed the config "C_Cpp.autocomplete" from "Default" to "Disable", but it still didn't work.
Without vscode-cpptools extension :

With vscode-cpptools extension :
No Matter "C_Cpp.autocomplete" is Default or Disable

I have found a similar issue : #189
But his autosuggestion works properly, though it seems like there is no IntelliSense.
Thanks!
