Read from begininning and end same time..

[Josh]

Is it possible to read a file from the beginning and the end at the same time in C++? The reason why I am asking is because I have a file with over 200,000 words and I am trying to figure out the best and fastest way to read and store them in my program.

You could try multi threading. Or you could do something like..

(the following is pseudocode, so don't rage at me and tell me its not valid C)
for int i 0 to lengthOfFile/2
read(file)
read(file[length-i])
endfor

I think you'll find however that multi threading would be the fastest way to do this.

Is that some BASIC? o.O

You talking about VB(Visual Basic?) It is just psuedocode that can be used for any language I would assume...but I was asking about C++

I know what pseudocode is. I was just noting that it looks a lot like BASIC. That is, I was wondering if he wrote it having had experience with BASIC but not C++, hence formated it as such as opposed to for(x; y; z){}.

I said at the top of my post it was pseudocode.

I am fairly well versed in C++ but the pseudo-code seemed more concise and language portable + I'm pretty lazy.

Yours:
for int i 0 to lengthOfFile/2

BASIC:
For i as int = 0 To lengthOfFile/2

They're very similar. Hence I was asking if the pseudocode was influenced by BASIC as opposed to being completely made up. Jeez.

Ok, well you weren't being very clear so don't be upset you didn't get a clear answer.

My pseudocode would probably heavily influence by Blitzmax because I find the syntax really easy. (http://en.wikipedia.org/wiki/Blitz_BASIC) Although I don't think you'll find a catch all file read function like "read()" in any language haha.

PHP has file_get_contents('file-name.txt') which reads the entire file. I <3 PHP.
