I'm making a program that can write RSS files. Now so far everything works right, except one thing, whenever I create a new RSS file (it can open or create a new one), it either doesn't save the file until it exits, which is bad because I need to read the file afterwards. This is my code:
The problem seems like it's not saving the file directly after I close it, because if I take out the check of the first line, it couts nothing, but if I leave it in it only couts the first line. And when I open the file it's the way it's supposed to be. So is there a way I can manually save the file? Thanks.Code://Headers
