Hi guys,
Does anybody know how to write all output to a file please? But trick is I am using Micosoft Visual C++ 2010 Express. There must be an options somewhere? I've not used it very long and don't know how to do this.
Thank you

What do you mean - write output to a file?

Thank you,
cout is made to, by default, output to the console. You shouldn't change that.
You should instead learn to use iostreams, ofstream to write to a file.
OK, I didn't know it was bad practice to do that, will keep it in mind.
Currently I am using an ofstream for 1 of the outputs:
But I also need to output a few other things to a file.Code:ofstream outputFile; outputFile.open ("MSE.xls"); // code outputFile << MSE << endl; outputFile.close();
So can I output several things to different files like this:
Is that correct?Code:ofstream outputFile; ofstream fileTwo; outputFile.open ("MSE.xls"); fileTwo.open("weights.xls"); // code outputFile << MSE << endl; fileTwo << weight[i] << endl; outputFile.close(); fileTwo.close(); // etc like this for several files to which I'd like to write
Thank you Elysia,
Yes, but you should also be able to shorten the code into this:
Note that there is no need to close. The files will automatically close once they go out of scope. This is an important technique called RAII.Code:ofstream outputFile("MSE.xls"); ofstream fileTwo("weights.xls"); // code outputFile << MSE << endl; fileTwo << weight[i] << endl; // etc like this for several files to which I'd like to write
OK thank you! Will greatly help.
Kind Regards,
