How to output in a .txt file?

[helfer]

Hi,

I have a programme that shows me a lot of values in the console. I would like to have the output information in a .txt file?

Can somebody explain me in a simple way how I can do this? Which commands do I have to add exactly?

I'd be grateful for answers!

If you're primarily using printf, open a file with fopen and write to it instead with fprintf().

If you're primarily using cout, open a an ofstream and write to it instead of cout.

Additionally,

1) you can run from the command prompt :

your_code.exe >output.txt

2) If using cout, you can redirect the output by appropriately
setting its rdbuf() to that of a file's rdbuf(). The main
advantage in this message is that you can switch between
outputting to the console or to the file at any time during
the running of the code.

Some error messages may be output to the stderr stream.

IIRC, you can redirect both stdout and stderr to file using.

prog.exe >2> out.txt

or possibly

prog.exe 1>2> out.txt

You probably can use SetStdHandle with a handle to the .txt file opened in write mode.
