ExaSec56 Member	Posted on 30/11/2021 at 14:33:44 by ExaSec56 Member Hello, 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.

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. --------------------------

Hello,

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.

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.
