Why does Visual Studio code tell me that cout is not a member of the std namespace?

Question

I am trying to set up a visual studio code for programming in C ++. I have already installed the C / C ++ and C / C ++ Intellisense extensions

Below is my code:

#include<iostream>
using namespace std;

int main()
{
 cout<< "hello" ;
}

The error I get is identifier cout is undefined, and when I write it as std::cout, I get an error namespace std has no member cout. Below is my file task.json:

{
"version": "0.1.0",
"command": "make",
"isShellCommand": true,
"tasks": [
    {
        "taskName": "Makefile",
        // Make this the default build command.
        "isBuildCommand": true,
        // Show the output window only if unrecognized errors occur.
        "showOutput": "always",
        // No args
        "args": ["all"],
        // Use the standard less compilation problem matcher.
        "problemMatcher": {
            "owner": "cpp",
            "fileLocation": ["relative", "${workspaceRoot}"],
            "pattern": {
                "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                "file": 1,
                "line": 2,
                "column": 3,
                "severity": 4,
                "message": 5
            }
        }
    }
]
}

How to fix it?

I have the same problem and I found this to be a vscode error. See the link below.

Answer 3

I am using VSCode version 1.22.2 with the MinGW compiler, and below the configuration works for me:

{
"configurations": [
    {
        "name": "MinGW",
        "intelliSenseMode": "clang-x64",
        "compilerPath": "C:/MinGW/bin/g++.exe",
        "includePath": [
            "${workspaceRoot}",
        ],
        "defines": [
            "_DEBUG"
        ],
        "browse": {
            "path": [
                "C:/MinGW/lib/gcc/mingw32/6.3.0/include",
                "C:/MinGW/lib/gcc/mingw32/6.3.0/include-fixed",
                "C:/MinGW/include/*"
                "${workspaceRoot}",
            ],
            "limitSymbolsToIncludedHeaders": true,
            "databaseFilename": ""
        }
    }
],
"version": 3
}
