[cppvsdbg] Allow stdin to the debuggee

Type: Debugger

Describe the bug

• OS and Version: Windows 10 (1903)
• VS Code Version: 1.39.2
• C/C++ Extension Version: 0.26.1
• Other extensions you installed: CMake Tools (1.2.1)
• A clear and concise description of what the bug is.
  When launching the console debugger, COUT text is displayed correctly. CIN input is not passed to the program.

To Reproduce
launch.json:
launch.json.txt

main.cpp:
main.cpp.txt

Debug console output...

Additional context
I'm teaching a C++ data structures class in January. I'd really like to use VSCode (instead of VS and XCode). But I need local debugging working.

Riproduci il problema con i file launch.json e main.cpp allegati su Windows 10, quindi analizza il percorso di input della console cppvsdbg. Conferma che l'input immesso durante una sessione di debug della console raggiunga il cin del debuggee; completato quando il programma di esempio riceve ed elabora stdin invece di uscire senza di esso.
