What is file mode in c++ ?

Question

anyone explain this to me guys..

Answer 1

What exactly do you mean by file mode? Do you mean things like fstream objects?

Answer 2

no it's iOS concept..

Answer 3

you mean 'read-only' (you cannot modify the file contents, only read them), 'write' (you can overwrite the file contents in this mode), 'append' (when you write to the file, the new content is appended to the old contents), 'binary' (you work with the file in non-text mode - for instance, editing a music file).
