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 

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
