What’s wrong with this line of code?

bar foo(vector ftw);

It produces

error C2061: syntax error: identifier 'vector'

try std::vector instead. Also, make sure you

#include <vector>

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);

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>

try std::vector<odp> or using std;

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);

Question
HI, thanks for the help.

I can’t use ‘vector’ in cli at all. I would like to make a vector of classes. I have the following code:

#include<cliextvector>

static vector<CEntry^>^ entry = gcnew vector<CEntry^>();

I get missing ‘;’ before ‘<‘ and missing type specifer — int assumed. Can you please help?

Thank you very much.

It’s in the cliext namespace:

static cliext::vector<CEntry^>^ entry =
gcnew cliext::vector<CEntry^>();

I am having a C2061 error on the private methods on my classifier.h file. As you can see, I have #include vector, and i am using it for a public struct. Can someone please help me understand what I am overlooking?

#ifndef CLASSIFIER_H
#define CLASSIFIER_H

#include "patient_data.h"
#include <QObject>
#include <vector>
#include <stdlib.h>

    Q_OBJECT
public:
    explicit Classifier(QObject *parent = 0);
    ~Classifier();
    void classify(std::vector<patient_data>data, patient_data i);


    struct CreateSDTable
    {
        std::vector<int>sum[3];   //element 0 = Tumor, element 1 = Stage, element 2 = Adjuvant
        std::vector<long>mean[3];
        std::vector<long>error[3];
        std::vector<long>SDL[3];
        std::vector<long>SD[3];
    };

    CreateSDTable CurrentvsNeutropenic;
    CreateSDTable CurrentvsNonNeutropenic;
