I am using ofstream to output something to a file called outFile2, however, when I need to call another function named "prettyPrint" that I pass in the outFile2 as a parameter in order to read from that outFIle2 again, the error message of "No matching function for call to 'prettyPrint' " shows up.

I first declared ofstream outFile2, then outFile.open(argv[3]);

then I closed it after finished using outFile2.close();

now, I want to reopen it again as a istream to pass into another function as a parameter.

How do you pass the outFile2 as a ifstream into another function as a parameter if it is declared as ofstream before?

This question is surrounding c++.

Thank you!
