In regard of performance, why should I rather use "immutable
string" over "const string*" (or just "string*")?
For example, as a function argument. When I have a loop which
calls a function with a string argument. (And to avoid function
inling in this example the function call is also used in several
other places.) It's better to use a pointer instead of every time
coping the content of the original string to a new immutable
string, right? Or is the optimizer somehow treating the immutable
string in another way I'm currently not aware of?
Is there an example of a usecase for better using "string" over
"string*"?
Just want to figure out how to do it the "right" way.
