I have a very simple hello world code as shown below:
#include <iostream>
int main()
{
std::cout << "Hello World!";
return 0;
}
I am trying to compile it in VSCode powershell terminal of Windows 10. I am using VS Community 2019.
Here is my directory structure:
When I do a cl triplex.cpp I get this:
but then at the next step when I try to run the program:
triplex
I am getting this error:
I have seen many posts with this error but none of them actually solved up my issue. Someone please help me getting out of this problem.
As suggested by #d4rk4ng31, It executed using ./triplex. Thank you so much guys.
its very simple download mingw installer ,set its path in environment variable,for compiling in vscode just type command:-
g++ (name of file).cpp
2nd command :-
a.exe

So I am really new when it comes to C++, and have tried learning it.
So far I have installed the MINGW64 MYSYS2 thing for the gcc, gdb and g++ (compilers?). And have created my workspace.
Whenever I try to print the "Hello World" statement, it won't print it for some reason? I really have no idea what I am doing wrong. Can someone please help.
Code:
#include <iostream>
int main() {
std::cout << "Hello World";
return 0;
}
Output:
* Executing task: C/C++: g++.exe build active file
Starting build...
"C:\Program Files\Haskell Platform\8.6.5\mingw\bin\g++.exe" -fdiagnostics-color=always -g "C:\Users\bsdwi\Documents\Visual Studio 2017\C C++\HelloWorld\HelloWorld.cpp" -o "C:\Users\bsdwi\Documents\Visual Studio 2017\C C++\HelloWorld\HelloWorld.exe"
Build finished successfully.
* Terminal will be reused by tasks, press any key to close it.
Followed by this pop-up message:

Has it got something to do with the Haskell thing? I am so new to Visual Studio Code and C++ so I'd really appreciate any help.
And apologies in advance if I have missed something out that you guys need in order to help me. Please let me know if you require more information.
I'm a beginner in learning C++ programming and just started to use IDE VS Community 2022.
I've created the new project corresponding to tutorial and when i run it i get the messege in the console:
C:\Users\??????\source\repos\HelloWorld\x64\Debug\HelloWorld.exe (process 12192) exited with code 0.
The code is
#include <iostream>
int main()
{
std::cout << "Hello, world!";
return 0;
}
I know it's not an error, but is there some of solution to remove this message?
Thank you in advance!
This is a feature of the IDE you are using. Try to run your program using the command line prompt directly and the message will not be displayed.
I've tried using Notepad++ to code c++ and followed a few tutorials on youtube, here's what I did:
-Installed gcc/g++ compiler using mingw64
-Installed NppExec plugin on N++
-Typed in the following compilier script and saved as C++:
NPP_SAVE cd $(CURRENT_DIRECTORY) g++ $(FILE_NAME) cmd /c $(CURRENT_DIRECTORY)\program.exe
Anyways whenever compiling a program, for example a simple program
#include <iostream>
using namespace std;
int main(){
cout << "Online\n";
system("pause"); //So that cmd doesn't disappear immeadiately on running.
return 0;
}
The console displays the following warning:
"C:\Users\pc\Desktop\Courses\Projects\C\program.exe' is not recognized as an internal or external command, operable program or batch file."
My question is, When I run the program on cmd, it runs perfectly but the error displayed during linking says that the folder does not exist in %PATH%
Any explanation?
Thank you!
Ok so, what I basically did was change the script,
cmd /c $(CURRENT_DIRECTORY)\program.exe
To be later
cmd /c $(CURRENT_DIRECTORY)\a.exe
the console worked fine and even received input
Here is a link to a similar problem:
How to compile/execute C++ code from within Notepad++
I am a first time C++ user, and I have been working for 8 hours trying to build and compile the simple "Hello World" program with C++ in Visual Studio Code. I have CygWin64, but I'm not sure if it's connected to my VSCode. I have installed the extensions C/C++, C/C++ Compile Run, C++ Intellisense, Clang-Format, and Easy C++ projects.
So far I have tried
#include <iostream.h>
main()
{
cout<< "Hi there";
return 0;
}
and
#include <iostream.h>
int main() {
std::cout << "Hello Easy C++ project!" << std::endl;
}
Using iostream.h helped me to get to work (it wouldn't at first), but I'm not sure if that is helpful, since other posts say that .h is very archaic. I have also tried editing my c_cpp_properties.json file. Sadly, I still get the message:
"> Executing task: bash -c "make run" <
'bash' is not recognized as an internal or external command,
operable program or batch file.
The terminal process terminated with exit code: 1
Terminal will be reused by tasks, press any key to close it."
I am not sure if I need to install an alternative to Clang (I haven't found one), or run something initially on Cygwin64.
I have been looking online for suggestions and following pages such as https://dev.to/acharluk/developing-c-with-visual-studio-code-4pb9 and https://github.com/Microsoft/WSL/issues/1598, but I still can't seem to get around this problem.
Any help would be very appreciated.

i wrote a program in my mac using sublime text as the plateform..
#include<iostream>
using namespace std;
int main()
{
cout<<"HELLOW WORLD";
return 0;
}
this was my program..
i saved it in desktop as hellow.cpp
while compiling on mac terminal as g++ hellow.cpp, i found an error
adarshs-MacBook-Air:Desktop adarshak$ g++ hellow.cpp
xcrun: error: invalid active developer path
(/Library/Developer/CommandLineTools), missing xcrun at:
/Library/Developer/CommandLineTools/usr/bin/xcrun
anyone plese help me to find out the error
It sounds like you don't have the command line developer tools installed. Run this command from Terminal once:
xcode-select --install
This will bring up the download & installation UI. Follow this through to the end. (It may take a while depending on the speed of your internet connection.)
From then on compiling should work.
