error C2061

: error C2061: syntax error : identifier 'density'

I have done quite a bit of research about this error on the internet. It seems as if the common answer is that there are either extra brackets somewhere of that I am trying to define my variable in some incorrect ways. I checked my brackets and they seem fine to me and I moved all my variables outside the main function. The error occurs when I try to use density for the first time. This is in line 61. The code is not complete yet because I'm trying to find errors as I go instead of ending up with an overwhelming amount when the code is complete. Any help or advice is appreciated, thank you greatly.

A while loop is declared like this :

while()

As apposed to this:

do while()

At least thats what I found

[helios]

Line 36: It's while, not do while.

//checks at the start of the loop
while (/*condition*/){
    //code
}

//checks at the end
do{
    //code
}while (/*condition*/);

:P You stole my answer

Ha. Wow. Perfect answer. I completely missed that. I had been changing back an forth in between the two and apparently forgot to delete the do after copy pasting the while. Thank you very much (both of you), fixed the problem right up.
