Why is visual studio code telling me that cout is not a member of std namespace?

Question

I am trying to setup visual studio code to program in c++. I have already installed the extensions C/C++ and C/C++ Intellisense

Following is my code:

#include<iostream> using namespace std;  int main() {  cout<< "hello" ; } 

The error I'm getting is identifier cout is undefined and when I write it as std::cout the error I get then is namespace std has no member cout . Following is my task.json file:

{ "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 do i fix this?

Answer 1

Its a bug.

There is a workaround for this bug, go to File -> Preferences -> Settings in VS Code and change

"C_Cpp.intelliSenseEngine": "Default" to "C_Cpp.intelliSenseEngine": "Tag Parser"

Answer 2

I am using VSCode version 1.22.2 with MinGW compiler and below config 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 }
