This actually appears correct ...
The 1-st example:
Each call to makeCalculator() increments a static (i.e. shared
among all makeCalculator() instances) variable - context.
In addition, makeCalculator() generates a random variable.
Whereas the delegate merely captures these variables, and the
displayed results reflect this.
The 2-nd example:
There is a single call to makeCalculator().
After this call, context == 1, randy == _apparently 2_.
Now the delegate, as has already been said, merely captures
these values, so consecutive calls do not change the result.
Thanks. So,
auto calculator = makeCalculator();
is the actual call of the delegate? "Delegate is function pointer
with context"
But what is
...calculator(0));
Or maybe another approach would be to ask, what type is the
compiler replacing auto with.
