Question

I need to write all my program output to a text file. I believe it’s done this way,

sOutFile << stdout; 

where sOutFile is the ofstream object that creates the file like this:

sOutFile('CreateAFile.txt' ); // CreateAFile.txt is created. 

When I insert the stdout into the sOutFile object, I get some code which seems to resemble octal [hexadecimal] code or an address of some kind in the text file that I created.

0x77c5fca0 

But what’s confusing to me is that in my program I use cout several times. Mostly just literal statement. If I’m not mistaken that is the program output.

If this code is an address, would it contain all of my output? Could I read it back in to the program and find out that way?

What can I do to get ALL of my program output written to a text file?

This is a duplicate of: this question

You can redirect stdout, stderr and stdin using std::freopen.

From the above link:

/* freopen example: redirecting stdout */ #include <stdio.h>  int main () {   freopen ('myfile.txt','w',stdout);   printf ('This sentence is redirected to a file.');   fclose (stdout);   return 0; } 

You can also run your program via command prompt like so:

a.exe > stdout.txt 2> stderr.txt
