auto Vs auto*

I am aware that auto does not hold reference, constantness and volatile until explicitly specified for auto What about auto and auto* Refer code below : I am holding reference of pointer pp into auto p as well as auto* p Both shows same result ... Why so ? Auto and auto* is same ? I thought auto p means pp and auto* p means &pp... Isn't it ? https://code.sololearn.com/c9DBnEl76iJM/?ref=app

There is no difference between "auto" and "auto*" here as compiler is smart enough to deduce the correct type of "p" as a pointer to integer in both cases. difference between auto and auto* becomes apparent in use cases where you want to make sure that the deduced type should strictly be a pointer. For example, when you want to declare const pointer ``` const auto* const p = something ``` Or when you want to make sure that the value that you are initialising is a pointer. ``` int c = 10; auto *p = c // this will throw error auto p = c // this will work and "p" would be deduced to "int" type ```
