Re: help reading binary into a vector for manipulation?

I feel like a dummy. That part with "iter ==" was a common mistake in c++ class that I usually spotted and corrected in other peoples code. Thanks for pointing it out.

Re: help reading binary into a vector for manipulation?

why did unsigned not work and what about the &?

It still gives "error...program has to close" unless I put the ios::ate back in. For some reason, that makes it stay open, but it's not printing out...

Re: help reading binary into a vector for manipulation?

Any good books specifically for this topic?

When you say "while (in.get(&byt);

Re: specify line of file to start reading?

I tried this and it is counting and skipping the first two lines but now the second "while" is not using commas as a delimeter. It's reading them into the vector. How can I delimit with '\n' and then...

Re: specify line of file to start reading?

sorry, I don't know anything about flags or how to use a boolean to check if the line already exists.
