What\'s wrong with this line of code?
bar foo(vector ftw);
It produces
error C2061: syntax error: identifier \'vector\'
try std::vector<odp>
or using std;
try std::vector instead. Also, make sure you
#include <vector>
Do you have:
#include <vector>
and
using namespace std;
in your code?
<vector>
defines the std::vector
class, so you need to include it some where in your file.
since you're using vector
, you need to instruct the compiler that you're going to import the whole std
namespace (arguably this is not something you want to do), via using namespace std;
Otherwise vector should be defined as std::vector<myclass>
Probably you forgot to include vector and/or import std::vector
into the namespace.
Make sure you have:
#include <vector>
Then add:
using std::vector;
or just use:
bar foo(std::vector<odp> ftw);
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<class T> struct vector {};
bar foo(vector<odp> ftw);
