Hi
I dont think that using pointers can be faster than
using local variables.
In some case,s it might be equal but can never be
faster.
In case of accessing the memory for pointer needs to
access the data on the heap and there is one
indirection also involved.
Bit on case of normal variables they are accessed
using direct stack memory.
Please give your comments.
Thanks
