Problem with passing input to std::cin during debugging C++ in VSCode

Question

Type: Debugger

OS: Windows 10
VS Code Version: 1.42.1
C/C++ Extension Version: 0.26.3
No other extensions installed
A clear and concise description of what the bug is: The main issue that I have is the inability to pass input to std::cin using VSCode debugging tool for C++. I tried different things that I found online, the main one was enabling "externalConsole":true in the launch.json, but in vain. In fact, when I do that, an external console appears, but it seems 'bugged', since it has a blinking cursor, but when I write into it, nothing happens.

Here is a screenshot of the 'bugged' external console:

Here is my launch.json configuration:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "g++.exe build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "C:\\MinGW\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "g++.exe build active file"
        }
    ]
}

Here is the code sample that I am trying to execute:

#include<bits/stdc++.h>
using namespace std;
int main() 
{
    cout << "Hello";
    string name;
    cin >> name;
    cout << "Hello " << name;
    return 0;
}

Have you always had this problem with cin? When was the last time cinworked in VS? — JohnFilleau

Actually cin works fine in 'normal' mode (without the debugging tool). The problem occurs when I use the debugging tool. — Mohamed Aziz Tousli

That's maddening. I'd just aim to reinstall and hope that fixes it. — JohnFilleau

Just do "externalConsole":true in the launch.json under the .vscode in your working directory. After that an external Terminal Window will appear, enter the input after you hit STEP OVER while on CIN!

Problem solved. I just needed to step over in VSCode debug interface so that the external console let me write in it.
