Hi, I am writting a program that needs to read a file once, do some calculations, then read it again from the top and perform some new calculations. I have been able to read the file the first time using and then tried to read it again with a similar loop later in the program. The second time it didn't read the file. Am I going to have to close and re-open the file in between reads or is there are more sensible way?

Thanks

You should use the rewind() function immediately before your second loop:

Well you're lucky. The feof() function should not be used in loops. See this link in the tutorial for an explanation.

As sdeming said, use rewind(). Or close and reopen the file as you surmised. Either is acceptable.

Ok, thanks for your help. I've got it worked using the code in the tutorial and the review() function.

Thanks
