Meaning of error "new types may not be defined in return type"

Urgent Help needed!


Hi there!

I am getting the following error on my compiler when i compile some programmes

"new types may not be created in return type".

These programmes are sometimes identical to the solution code provided in the tutorial letters.

I cannot trace this error.

A similr error that I cannot understand is :" extraneous int"

Please could someone help urgently.

I am using the dev IDE in vista. I am not sure whether that makes a difference.

thx.

Do you have any examples that you've gotten these errors with? The MinGW compiler has been known many times to give vague error messages so it helps if there's a context.

Thanks
the example is the solution code provided for question2 of Assignment 2

the solution code provided for question2 of Assignment 2 will solve your problem

but its not solving the problem.

I reproduce it hereunder. there may be very slight variances from the actual solution code but this should not affect compilation.
I'll really appreciate an experienced coder's help.
Thanks

There's no function called 'local'. If you are trying to call the constructor, you must do this at the time of creation (ie the previous line).

Thanks alot . Really appreciate the help.
but its still giving the same error.

do you think i should try and use another IDE like ms visual c++?

and by the way there is also another error that says: "main must return int"
I wonder what that means.
