Let's say I'm writing to a file a series of integers like this: 4 3 2 1 0 After writing the last number (or the last line), can I delete that last one?

can I open a file and then close it in a loop? I tried but it doesnt seem to work. :(

Can I change a file stream object's read position in C++? I mean I have a file with a series of integers separated by a newline character. Can I read the first five integers into some variables and then move the read position back to read the fifth integer one …
