I am building a project in C++/Fortran and I am using Visual Studio. However, I am facing an issue. When I try to print a value either in C++ or in Fortran, the value is printed on the console of Visual Studio but the console is quickly closed automatically after opening so I cannot see anything.

For example, when I do this in C++:
std::cout << "text to print" << std::endl;

I cannot see the printed text since the console does not stay open.

Is it possible to redirect all outputs from Visual Studio to somewhere else or a file instead of printed them on the console without changing the code?
Thank you.

Hello ExaSec! 🙂

To redirect all standard outputs to a text file in Visual Studio without changing your code, you can modify the properties of your Visual Studio project.

You can do the following:
  • right-click on your project
  • go to Properties
  • go to Debugging in the left panel
  • add an instruction in the "Command Arguments" field

For example, you can add
> test.txt

to redirect all standard outputs to a file named "test.txt" which will be created if it does not already exist or overwritten if it already exists.

You can of course do the same for the standard errors.

I hope it helps.
