there is no + after the select statement and before concat of the combobox1
Berkus
it depends on the operator _associativity_
Berkus
some operators associate left-to-righ, others right-to-left

hi,
is there a way in C++ to make a function automatically called when a virtual function return?
I have a pure virtual method that will be reimplemented and I would like that at the end of the method a function will called without who reimplement the method has to call the other function at end
Isc
class A { virtual bool x() { ... } }
class B : public A { bool x() override { ... + return A::x(); } }
AndrEEa
but who reimplements the class has to call A::x() manually
AndrEEa
I already do it
AndrEEa
I would like automatize the call
Isc
well, you can create a proxy class but i wouldnt recommend it
Isc
you know, base should always be called, everyone knows that
Isc
if im overriding your method, ill call base by instinct
Berkus
although it's a LOT of boilerplate just to "automatize" the call that should have been explicit always (remember, in C++ explicit is better than implicit)
Isc
struct MyClass
{
bool x();
}
struct ImplicitBase
{
virtual bool x();
}
template<typename TProxied>
struct MySuperProxy
: public TProxied
, public ImplicitBase
{
bool x() override
{
ImplicitBase::x();
TProxied::x();
// return what?
}
}
AndrEEa
btw what "override" means exactly? what if I omit the string?
Isc
MySuperProxy<MyClass> lol;
lol.x();
Isc
Berkus
btw what "override" means exactly? what if I omit the string?
it means this concrete function is an override of virtual function; not a separate function with the same name
AndrEEa
yes but it's optional I see
AndrEEa
I never used it but I will
Isc
yes but it's optional I see
yes it is, but is a good practice to use it, same as noexcept, const or final

I want to host online radio station, any help please
Berkus
yes but it's optional I see
it's recommended to use it on c++11 and later projects; it's optional only for compatibility with old code (and because it could be a non-override function overload with the same name)

i want your help please ⚠️
Write a program that reads a file named notes.txt that contains on each line a note (float) followed by a semicolon and a student's name and writes a file named birthday.txt that contains the same information with each note increased by 2 points (but not more than 20).
Here is an example of a notes.txt file. Note that the file ends with an end of line as the last character.

If the worst situation, which is brought by an attempt, is acceptable and repairable, then you could give a try.

Probably you can try voidlinux

there are some project of arch linux systemd free but are extreme instable. I switch to gentoo because it was more easy than erase systemd from arch. Btw systemd isn't the that bad
