C++ Importing and Renaming/Resaving an Image
Greetings all,
I am currently a rising Sophomore (CS major), and this summer, I'm trying to teach myself C++ (my school codes mainly in Java).
I have read many guides on C++ and gotten to the part with ofstream, saving and editing .txt files.
Now, I am interested in simply importing an image (jpeg, bitmap, not really important) and renaming the aforementioned image.
I have googled, asked around but to no avail. 
Is this process possible without the download of external libraries (I dled CImg)? 
Any hints or tips on how to expedite my goal would be much appreciated
