ifstream

[vsgdp]

Hello,

Suppose I use one ifstream object for the life of a program.

If the user opts to load/save I call

inFile.open(...);

....

inFile.close();

Whenever the menu item is selected.

However, this does not work. I was able to get it to work by calling:

inFile.close();
inFile.clear();

But my question is, why must I call the clear method?

Usually because you cause it to become bad somehow, like an attempt to
read beyond its end...
