Question

I have problem i need to convert from my “Array” structure to std::vector<int>… the point is i have a dynamic matrix who purpose is being Database. But at some point i need to move some values from the ‘Array’ to a vector. and i get the fallowing error

 c:\mingw\bin\../lib/gcc/mingw32/4.6.1/include/c++/bits  /stl_iterator_base_types.h:166:53: error: 'int' is not a class, struct, or union type

Anyone has some clue how to achive this thing?

structure:

const int days=31;
const int exp=6;

struct Arr{
    int days;
    int exp;
    int **M;
};
typedef Arr* Array;

vector:

 vector <int> vec(31);

EDIT:

int dayExp(int day, Array &M){
    int s=0;
    for(int i=0;i<6;i++){
        s += M->M[day][i];
    }
    return s;
}

void srtDesc(Array &M){
    vector <int> vec(31);
    for(int i=0;i<31;i++){
        vec[i]=dayExp(i, M);
    }
    sort(vec[0],vec[1]);

    for(int i=0;i<31;i++){
        cout<< vec[i];
    }
}

Your Arr struct does not implicitly convert to int. First of all, your struct contains 3 int types, whereas a vector<int> is one int at a time.

If you want to put your Arr into a vector, you should create a std::vector<Arr> and then call push_back on it to put your Arr structs in it.

std::vector<Arr> myvec;

myvec.push_back(someArr);

You will need to create for loop that goes through the length – 1 of your array and calls push_back to put each item in the vector
