I am working on a program and need to make an array of objects, specifically I have a 31x1 array where each position is an object, (each object is basically built out of 6 ints). Here is what I have but something is wrong and i could use some help thank you.

31x1 struct header"

const int days=31;

struct Arr{

    int days;
    int *M;
};
typedef Arr* Array;

31x1 matrix constructor:

void constr(){
    int *M;
    M = new Expe[31]; // Expe is the class 

class header:

class Expe {
private:
    //0-HouseKeeping, 1-Food, 2-Transport, 3-Clothing, 4-TelNet, 5-others
    int *obj;
}

Class object constructor:

Expe::Expe() {
    this->obj=new int[6];
}

help please... because i`m pretty lost.
