I tried to compile a simple Hello World in C++ to test that my Visual Studio 2013 on my Windows 10 works well but I've a problem. My program compile but when I run, it freeze. It's an empty Win32 Console Application with a "main.cpp" :
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world!";
return 0;
}
If I launch it from Visual Studio in debug (with "Run"), Visual Studio freeze and I need to kill its task.
If I launch it with the executable or with "Run without Debugging", nothing appear, "System" process doesn't want to free the execution and I can't recompile without restart the computer because of that.
I am confused. If somebody have an idea of what's happening, please help me.
Update 1 : I repair my installation. Same problem. Breakpoint doesn't help. It seems to freeze before. And also no trace of a task in the task manager when launched without debugging.
It was my antivirus' fault (in my case, Avast). I made it ignore my Visual Studio projects and it works. Solved by #Blastfurnace.

i am new and i was trying to learn c++, so i open my visual studio 2019, then create a new console application and click the run button.
This is the autogenerated code:
#include <iostream>
int main()
{
std::cout << "Hello World!\n";
}
any idea?
To fix the error, i go to Tools > Get Tool And Features...
Then i installed Windows 10 SDK (10.0.19041.0)
and now my program works! Someone know the reason why the SDK is not installed by default?
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.
Thanks,

I have this well known c++ program in my Visual Studio 2015 Prof:
#include <iostream>
int main(int argc, char* argv[]) {
std::cout << "Hello World!" << std::endl;
return 0;
}
As expected, it shows "Hello World!" if I hit Ctrl+F5. However, if I go to the directory within an cmd.exe and execute the HelloWorld.exe file, it doesn't show anything as output, but does quit (I can type in again).
According to a similar question I checked the settings of the project but I did not need to change anything, the Configuration Properties -> Linker -> System -> SubSystem already is at Console (/SUBSYSTEM:CONSOLE).
Flushing the std::cout also didn't help anything. It is reproducable on every freshly created project of VS2015 on my Win 7 64-bit machine and seems to be presistent after rebooting.
What is wrong with my IDE / settings?
After the hint of #Scheff I threw the exe file into "Dependency Walker". It gave me a missing UCRTBASED.DLL and lots of second and third level missing dlls (I think this is usually the case on every application?).
I somehow think my (recently installed) anti virus did interfere with that, because it shows some messages in the log regarding my HelloWorld.exe.
However, deinstalling anti virus and restarting machine did the trick. I can finally see Hello World! on cmd.exe.
It's been days since I try to make my IDE (Code::Blocks version 13.12, I tried on 10.05 too) work. Any program (including a simple Hello World! program) I would make would show a black console showing nothing but an " _ ". I have made an exception in my antivirus (Avast!) for the file containing the IDE) but the same thing happens . I have tried re-installing twice, i have tried resetting the compiler and debugger's settings to default, auto-detecting toolchain executables ,but the same thing happens.
I have tried rebooting my computer several times, same thing happens.
I would like to know what I can do to solve this problem , because I don't want to get another complicated compiler (I am a beginner,) , as Code::Blocks fits my needs perfectly.
The following codes produces a blank console:
#include <iostream>
int main()
{
std::cout << "Hello world!\n";
return 0;
}
I had the same exact problem, with Eclipse, Visual Studio and then with Code::Blocks (I tested them all). I suggest you follow this video tutorial after you confirm the problem persists with a second IDE : https://www.youtube.com/watch?v=zOGU8fC3bvU&index=6&list=LLHcXdIeBMN4XYRZAk4IeXmg&spfreload=10 . It will take you step by step on how to install a given compiler.
This question already has an answer here:
Running my C++ code gives me a blank console

Closed 7 years ago.
Whenever I press F5 to compile and run a C++ program in Visual Studio 2013, the program stops responding without outputting any error. The cursor becomes busy and the application just hangs.
Here are the steps:
Create a new Visual C++ console project
Unselect everything to make it an empty project.
Add the following code to a main.cpp:
#include <iostream>
int main() {
std::cout << "Hello World!" << std::endl;
std::cin.get();
return 0;
}
Compile: works fine
Run with debugger: Mouse turns busy and app becomes unresponsive.
It seems to work when I run without debugging, but there are no console outputs to check. Updated to latest VS2013 release and rebooted the computer just in case there's an error. Running in Windows 10.
There were at least two times here at Stack Overflow where others had something similar happen, and it was due to Avast anti-virus software. If you're using Avast, you might want to see if there's a workaround.
