Allocating an array of C++ objects

Question

I want to allocate an array of C++ objects using the following code:

class myClass {
public:
    myClass(int userValue)
    : value(userValue)
    { }
}

private:
    int value;
};

int main(){
    myClass* objArray = new myClass(22)[5];

    return 0;
}

But it gives me the following error:

In constructor ‘myClass::myClass(int32)’:
error: expected ‘;’ before ‘[’ token
         objArray = new objArray(22)[5];

How should I create an array of objects then while passing parameters to them?

**-1** not the real code. in the code you have manually written here, there's a missing semicolon after the `}` of the class definition. please always copy and paste real code. — Cheers and hth. - Alf, Nov 08 '14 at 15:20

Use std::vector.

std::vector<myClass> objArray(5, 22);

**+1** for `std::vector`. – Cheers and hth. - Alf Nov 08 '14 at 15:20
Thanks. But could you tell me the reason why it is not possible to allocate the objects array in regular way? – Arya Mz Nov 09 '14 at 05:03
