I regret seeing that

I love abusing C++ tho

Guys... I'm currently working with 'c in depth' book... Is this a good start for me as a beginner.

C is an old language

You should learn C++ first
BinaryByter
and learn C later if you really need to
olli
while ++i + ++i isn't
Well I consider it UB as well, although you probably gonna see the same result in every compiler.
Left or right side first?

doesnt matter since addition is commutative, or am I wrong?
Mark

So should i start learning c++ first... Ok any suggestions about sources books anything.
BinaryByter
Mark
That'll be great
BinaryByter
effective c++ is very good
BinaryByter
"effective C++"
BinaryByter
or the "C++ primer"
olli

That's why I would expect to see the same result everywhere although technically UB...
Mark
That's it...

"technically UB"?
BinaryByter
why is it?
BinaryByter
sure

Hi,
I have developed a project called ezored (https://github.com/ezored/ezored or https://ezored.com), that is a ready to use project that join C/C++ for mobile and desktop platforms. I have added more docs and more fixes. You can check repository and if you can STAR our project on github to help us. The main goal is use same base code in C/C++ on all platforms and let the teams only make specific platform code, like interfaces, dialogs, screens etc.
Thanks.
Anyone looking to announce a project can do it using this group. Feel free to redirect anyone here:

"technically UB"?
because the + operator does not define a sequence point. So the side effect is unsequenced relative to the value computation yielding UB

just "Undefined sequence of operation" doesnt make UB
BinaryByter
else every op would be UB
BinaryByter
and every funciton call before cxx17

it does if there are side effects. ++ is a side effect

olli

What's the result?
struct Foo {
int x;
friend Foo operator + (Foo a, Foo b) {
return { a.x / b.x };
};
Foo& operator++() {
++this->x;
return *this;
}
};
int bar() {
Foo f1{1};
Foo f = ++f1 + ++f1;
return f.x;
}
BinaryByter
oh THATS why its undefined

Guys how to write a c function to add two fractions using structure and integer as data types
BinaryByter
We won't code for you
BinaryByter
Instead, ask more specific questions
BinaryByter
there is no concept that makes that problem different
Anonymous
Can u ellobrate how to do I not getting it so
Anonymous
Plz
BinaryByter
no, ask a specific question
BinaryByter
help me with helping you

- get the same denominator
- add them

i am new to C++... ai using codeblocks...but it doesn't seem to recognise the #include <iostream> or #include <iostream.h> directives....is it an issue that can be resolved or i just switch to another IDE?

hi
Pavel
Can I make a variadic that process elements of different type than the given ones?
Something like this:
template<typename... Args>
std::tuple<Args...> getValues(const std::tuple<std::vector<Args>&...>& containers)
{
...
}
But I want my input parameter to be typle of std::vector<BaseClass>...>&
for any given types
E.g. if I use <int, float> as template arguments, I want the signature to be
std::tuple<int, float> getValues(std::tuple<std::vector<BaseClass>&, std::vector<BaseClass>&>& containers)
But not
std::tuple<int, float> getValues(std::tuple<std::vector<int>&, std::vector<float>&>& containers)
as it now.
How I can achieve that?

Wow creepy name
Pavel
Are you sure that's the only way? Because it looks unreadable
It's a simplified version. The real one looks not readable at all :)
I don't see better way than templates to achieve that I want. all the implementations that I saw made on templates
Pavel
I'll refactor it later, for now I want it to work as I expect
Francisco

Trust me, you won't be able to read it in the future
Pavel

Yes, but that doesn't matter in this case, I do it for educational purposes. I can't afford to make a good-looking scalable and readable solution to throw it away right after that.
I want to shoot my leg enough times to be aware of what I should or shouldn't do. And now I can't load my revolver to do another try :)

Not the best way, but okay. I'll check it out later
