And here is my error:
error C2061: syntax error : identifier 'newWeight'
I have gone back to assignments like this one and I never got that error, could someone please point me in the right direction, thanks

am I missing something or have you missed something, what type is newWieght?
int, double?

Don't try to call main(); from within main().
Use the normal control structures such as the while loop, or an if statement to achieve the processing you want.
