C++: Syntax error C2061: Unexpected identifier

Question

What\'s wrong with this line of code?

bar foo(vector ftw);

It produces

error C2061: syntax error: identifier \'vector\'

Answer 1

On its own, that snippet of code has no definition of bar, vector or odp. As to why you're not getting an error about the definition of bar, I can only assume that you've taken it out of context.

I assume that it is supposed to define foo as a function, that vector names a template and that it is supposed to define a parameter called ftw but in a declaration anything that is not actually being defined needs to have been declared previously so that the compiler knows what all the other identifiers mean.

For example, if you define new types as follows you get a snippet that will compile:

struct bar {};
struct odp {};
template struct vector {};

bar foo(vector ftw);
