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?

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);

What's wrong with:

typedef auto_ptr<char> Char_ptr;
Char_ptr myAutoptrs[2] =
{
Char_ptr(new char('a')),
Char_ptr(new char('b'))
};

???

puts (myAutoptrs[0].get()); // a ?, no heap
corruption

return 0;
}

George
