MVECTOR(int siz)
	{
	size=siz;
	A=new int[size];A=A+1;
	}

int  &operator [] (int i) {
if (i>size) std::cout<<"Index exceeds matrix dimensions."<<std::endl;}

};
////////////////////////////////////////////////////////////////////

ARXEIO main.cpp

#include <iostream>
#include <new>
#include <memory>

#include "mvector.h"

int main()

std::cout<<"Start"<<std::endl;


aaa[12]=3;


std::cout<<"END";

}

Oriste to output
