From pointers and references; which one is more efficient in terms of memory usage?”

[itguy310]

Hello,

From pointers and references; which one is more efficient in terms of memory usage?

[Lindley]

There's no significant difference, especially once the optimizer gets involved.

Technically references are implicit pointers. There should not be differences.

thanks but what is difference in terms of memory? Detail please.................?

[Lindley]

How a compiler chooses to implement references is not defined by the standard, as far as I know. Thus there's no way to answer your question.

For all intents and purposes, you should consider them equivalent in terms of memory usage.

As Lindley pointed out, there is no standard way that references are implemented. If you have the C++ specification, the only thing that is mentioned about references is how they are supposed to behave, not how they're implemented.

There are no null references.
