In C++, how can I find the size of a function?
Assume I have a function:
... By "size of f," I mean the length of the code that will /*do something*/ beginning at the location specified by a reference to f.
This method worked for me.

In C++, how can I find the greatest or minimum value in a vector?
Is it correct to assume that it would be similar with an array?
Do I require an iterator?

Replace pow() with the previous iteration's value.
There is no need for code to call pow ().
Pow(x, 5 * I - 1) and pow(-1, I - 1) may be formed since both have an int exponent dependent on the iterator I from the previous loop iteration.

It's a little perplexing.
Function type and pointer to function type are distinct kinds (no more similar than int and pointer to int).
However, in virtually all cases, a function type decays to a reference to a function type.
In this context, rotting roughly refers to conversion (there is a difference between type conversion and decaying, but you are probably not interested in it right now).
What matters is that practically every time you use a function type, you end up with a reference to the function type.
But take note of the nearly - almost every time is not always!
And there are rare circumstances where it does not.
functionPtr fun = function;
This code tries to clone one function to another (not the pointer! the function!)
However, this is not feasible since functions in C++ cannot be copied.
The compiler does not let this, and I'm surprised you got it compiled (you say you got linker errors?)
Now for the code:

Hello, let's say I have an abstract class with a few pure abstract functions and a few classes that derive from it, and all of the data from these classes eventually becomes similar, I was wondering if it would be wise, or even possible, to declare a vector under protected in the abstract class to collect the data so something like that.
