Operand >> illegal

Trying to find which section has a higher average from 2 existing files (notepads)then writing the result to a third. However i'm getting that last 1,last 2, first 1, and first 2 are illegal function definitions or some such error. This is the first time i use files so any hints would be appreciated.

#include <iostream>
#include <fstream>
#include <iomanip>
using namespace std;

There's other errors I think but foremost, you should change void main() to int main().

You should also put your code around code tags [code](code here)[/code] for proper readability and indentation.

Other stuff:
* can't be used in a file name is most OSes, so your file streams will most likely fail to open.
~line 57, is_open needs to have parenthesis after it, it's a function.

and what are you trying to here?
 
 
while (first1>>" ">>last1>>" ">>grade1)

That was trying to add the spaces, although come to think of it i shouldn't have added them. That's trying to read the file

See the format section to the left right (edit: wow...) of your post when you click edit? Highlight your code and then press the [<>] button.
