I came from assembly, Python I still avoid like hell... I like C, now i am mostly going for a full C++, but still learning and asking people silly questions... Thanks to all of you guys for the help

Python is really helpful. You should give it more tries

Why don't you use smart pointers?

I have no idea, what is that?

Using raw pointers in modern C++ is mostly bad practice

Is it wrapper class for pointer with an operator overload ?

Yes

Using raw pointers in modern C++ is mostly bad practice

There're a few use cases, but smart ones should be the first one to be considered

That's makes sense now, I have learned about, but never dare to use... I will try now...

Of course But I said — mostly

Read Meyers book — Effective modern C++ He shows how to use them properly

But also much faster

There's always a drawback

But also much faster

unique_ptr is as fast as raw pointer in 99% times And I think it's a normal cost to avoid memory leaks and enhance code readability

Test it with a loop that loops 100000000 time and see the results by yourself

unique_ptr is as fast as raw pointer in 99% times And I think it's a normal cost to avoid memory leaks and enhance code readability

It is complicated. unique_ptr is about as fast and simple as a normal pointer in a no_except context but may have copy overhead and is not a trivial type

is this better, or not?

hello everybody, is ternary operator, more readable, than if/else ?

nullptr is not built in, but rather a variable of type nullptr_t, that's way safier than NULL

nullptr is built in

https://godbolt.org/z/pm0c18 What do you think? should i get rid of raw pointers, and switch to smart? And what's better to use for callbacks? How to impement singleton for ATimers in a proper way?

Hун! Working on a N-gram algorithm. The task is to make a map from the set of all (n1,n2,n3... n-1) words to the set of Nth words that follow the set of (n-1). Which collection should i choose to represent the set of (n-1). Doublicates must be allowed, thus set is not an option. Stack? List? Vector?

I want to learn c++ from starting i mean from basic can you guys plzz suggest me a website aur any other source from where i get the c++ knowledge from basic (beginners)

interesting. perhaps yes. if it had not existed what would have been my choice?

map( key, vector(value) )

@BOND_0O7 @unterumarmung @urinal In case you're interested, In the middle part the overhead of unique pointer is analyzed. https://youtu.be/rHIkrotSwcc

Can anyone help in (mobile price ) question in div 2

domain of the map (key) being what? either string or queue

string - may be but complicated addition of the last word and removal of the first word

i also think dequeue, remove from tail and add to head

Dequeue eats more memory, vector is slow in adding. But you must know number of trigramms for this particular word ,beforehand, so vector will do

But you can set enormous capacity of vector, then adding will be only O(1)

/ 100 and % 10

n / 100 * 10 + n % 10

Can anybody tell me why I'm getting that binary like code inside that box?

I didn't know this new rule

/warn read the rules (picture of screen + bad problem description with no code)

Program: Conversion of Infix expression to postfix expression using C

Am I allowed to ask that?😅

Will send code through Pastebin
