Binary '+=': no operator found which takes a right-hand operandi of type 'const std::chrono::duration<double,std::ratio<1,1>>'(or there is no acceptable conversion)

after a good sleep, I kinda got it to work with std::vector <int*> d {&a,&b,&c}

my ultimate purpose is to search from the vector for particular values and id them for further processing later. I might use map instead though. I'm not sure

sorry, it was something else, it was std::string foo()

Thanks, I've tried using debugger, but since i'm no expert using debugger, still couldn't explains why that bit of line behave certain way. It might as well I didn't use any :(

It kinda work but not 100%. Anyway, what just happen? what is this line? never seen one.

There's not much point to this code except for me understand the related C++ rules. I read few pages of C++ book and try writing some code of my own. The process repeated until I finish the book. Since the book couldn't answer some questions I have, so here I am, asking question, while trying to learn some new points you might kindly points out to me.

I passed playerNum as const ref to show that it won't return any value to it. From what I've read, it just a good practice.
If i'm wrong, tell me I'm wrong.

Enter name for player1: Enter name for player2:

This is the result in my code. It doesn't give me chance to enter name for player1 but instead just display it and skip it straight to player2.

Thank you :-)

Able to trim down the 1k lines of code to just 125 retaining the core functions.

Can I get new honest comment?
Please, I'm learning.

I mean standard C++ containers.

Nah it's ok. I expected that.
Originally, I did class inheritance from two base classes, but face some linkers error (my bad). So I just put that inheritance idea aside for a while and copy away those classes.

I will review my code and try to shortened it.
Thanks for the honest answer.
sigh.. I still have lots to learn.

Thanks for your feedback. I really appreciate it.
I should've use deque from the beginning.
I got it to work. The logic also have been fixed.
Take a look.

Can you comment a bit on my code. What can I do to improve it?
note: a lot of other code such as the operators are from initial testing when I first created those classes. Is it OK to leave it there?

Thanks, I'll look it up.
I also think that deque would be better since it is easier to access and pop the first element.
I also removes all the smart pointers and use basic deque because someone commented that STL containers put their elements on the heap anyway.

I updated the question. Hope it helps.

The problem didn't occur if I do push_back() within main() itself. It only happen when I move it inside a templated function.
template <typename b="" typename="" a,="">
void battle(vector &human, vector<b> &zombie){

while (!human.empty() || !zombie.empty()){
human.pop_back();
}
}

I initialize the vector like this:
vector<unique_ptr<warrior>> warriors;
vector<unique_ptr<knight>> knights;
vector<unique_ptr<goblin>> goblins;
vector<unique_ptr<orc>> orcs;

should I not use unique pointer then?

Are all STL containers dynamically allocated?

Thanks

Why it works when I write a constructor which didn't take any value?
Warrior(){
_health = 100 * randomize(0.7,0.85);
_attack = 100 * randomize(0.7,0.85);;
}
I will update the question above.

thanks, I regularly read that website and cplusplus.com
It just sometime (or usually) they explaining something using too much technical words and I ended up needed to reread the same sentence more than twice to really get the meaning :-)

Thanks.

Sorry about that. I posted new question though this time is about prefix increment and postfix increment operator of the same project.
I hope you're kind enough to look through it.
Thanks

Thanks, after fiddling around a bit i got it to work. I forgot add function that return the _armor value.

Warrior::Warrior(const Warrior& v):
Human (v),
_armor {v.getArmor()}
{}

I've updated my question.

I've updated my question. Sorry for wrong choice of word.

I already did ;-)

I agree that C++ is a tool of programming in general.
I also agree that I need to learn few programming language. Before C++, I learned Python for about a month.

The reason why I brought up the question is because I got stuck.
In my case, I stuck understanding the basic of:
1. User define type (class)
2. Function overloading
3. Pointers
Which really slow me down to the point that I stuck. These are very important to allow me to advance a little bit more in learning C++.

I'm pretty competent at computer (Techs articles is all I read everyday), you can name any productivity software, I've used it, Apart from the programming and other coding things .

I taught myself C++ through book and video tutorials.
I use both PC and Mac.
In PC I use Visual Studio 2015, and XCode in Mac.
Programming is the whole different beast though.

I'm still looking for the best way to learn C++ though.

Thanks, I've begun reading a thousand pages book on C++. I guess I've haven't reach the part yet.

Does 'template' means reading others sample code?
I practice coding using Visual Studio 2015.
What do you mean by managed and unmanaged?

Your condition works.

if ((input_diff > -2.0) & (input_diff < 2.0)) {
cout << "The value between the two is almost equal" << endl;
}

I never thought of that. Clearly I need more practice.
The reason for 0.1 and 2 is I changed it to see whether double is the reason it fail (and forgot to change it back).

I was reading the if statement like this: if input_diff is larger than -2 and smaller than 2, then cout the string (ignore the x=true;, it was from previous experimenting to make it work).

As for the '&', I copied it from another place, it should be a '&&'. But that didn't work too.

Thank You, I learned something here.
