The present is a c++ source program containing two lines commented
respectively CASE1 and CASE2.

Until this moment I can't find an explanation why CASE1 does not work.
I thing that POINTR1 and ARRAY1 are exactly the same type variables with
the same data.

The puzzle even grows by the fact that if we eliminate the & from the
parameter ARRAY in the prototype of FILLARRAY (changing ARRAY from
POINTER REFERENCE  to the older style POINTER TO INTEGER,  CASE1  works
fine.

Thank you for your help
Uri.





#include <iostream>
// #include <iomanip>
// #include <stdio.h>

void fillarray (int* &array)
{
for (int i=0; i < 10; i++)
array[i] = (2 * i);
}

int main()
{
int array1[10];
int* pointr1= array1;

 /* at this point array1 and pointr1 are the "same"
    and should be completely interchageable
*/

/*******************************************************************/

// fillarray (array1);   // CASE 1: compiler flags error/*

 fillarray (pointr1);    // CASE 2:  no errors as well as does the job

/********************************************************************/

for (int i=0; i < 10; i++)

cout << "   " <<  (array1[i])<< endl;
return(0);
