What does "expected unqualified-id" mean?

Warrax

I am currently doing online tutorials for C++, and am pretty much stuck in a rut about this problem. It is saying that there's an expected unqualifed-id before '{' token (I will post the code in just a second) on line 11, and an expected ',' or ';' before '{' token also on line 11, however I don't have a clue what the first one means. The program is meant to save a user's name in a string variable within a structure, and to then show that name without the need to assign a pointer to it. Also, note that I am compiling this with the Dev-C++ (aka Devcpp) compiler, on a Windows XP system.

11 C:\Documents and Settings\Main\My Documents\substring and structures.cpp expected unqualified-id before '{' token
11 C:\Documents and Settings\Main\My Documents\substring and structures.cpp expected `,' or `;' before '{' token

Could someone please explain to me what the "unqualified-id before" means, how to fix it, what I did wrong, and why it is the way that you say is the correct code?

Ok first let me post your code:
There are a couple of errors:
1. You have two mains
2. Structs should be declared outside of main

I think you need something like this:

When I put the struct before main and get rid of the 2nd main, this appears:

14 C:\Documents and Settings\Main\My Documents\substring and structures.cpp expected primary-expression before "name"
14 C:\Documents and Settings\Main\My Documents\substring and structures.cpp expected `;' before "name"
14 C:\Documents and Settings\Main\My Documents\substring and structures.cpp At global scope:
17 C:\Documents and Settings\Main\My Documents\substring and structures.cpp expected unqualified-id at end of input
17 C:\Documents and Settings\Main\My Documents\substring and structures.cpp expected `,' or `;' at end of input

Any ideas?

Could you please post the exact code that you used?

You never put the closing brace on the struct. Also, remember that you need a semicolon as well. Did you see the code I posted in my previous reply?

sorry, I have no idea - all replies to this question give alternative codes, but don't explain what unqualified-id means.

my850+ page book on C++ does not mention either id or unqualified in its index.
