what is the Agent inside the Agent class? a constructor?

Yes, it should have been a constructor. I just missed the "( )" there. I read a basic book, but it did not help - the "detail" was invisible to me.

Need a personal instructor to help with college first semester coding . Preferably indian . Dm me if anyone wants to help . Thank you .

This is getting a little off-topic... You would fit in better over at the "Cwithme" Telegram group.

What do you mean?

The program is to print till the first non alphabet character My code is:

#include<stdio.h> #include <stdlib.h> int main() { char a[1001]; scanf("%[A-Za-z0-9]s",a); printf("%s",a); } but only 4/11 test case passed I know that I can use isaplha but I just wanna know why my code didn't work could anyone help me out

in theory, i know c++ well, but i had not used it directly since many years ago, and now i have a bit of dyslexia, which helped me (i guess) not seeing the silly mistake for a few days, and concluded it was another kind of problem - which is fairly common to me.

long have i suffered to make it work , but finally it works though something distubs me

What do they consider in alphanumeric characters? Because some characters like & and @ are also considered alphanumeric

yeah thanks for your previous reply it's actually only till alphabets.I'm Sorry

I don't actually know C++ and couldn't say if this has memory leaks or other badness. https://nekobin.com/tebukihota

No "s", only the "[...]" part. The test that seemed to pass would have had a final 's' character and truncated it.

Guys Hi, I have a problem with C

What is database admin utilities

How can we write in c language

Any one help me

I can't return result[] in method "percorso". I have an error here oordinate* per1[SO_HEIGHT * SO_WIDTHS] = percorso(ts, cord, mat,a); if(ts[a+1] != NULL){ coordinate per2[] = percorso(ts, cord, mat,a+1); a1 = contaPercorso(per1); a2 = contaPercorso(per2); } if(a1 < a2) { vicino = ts[a]; }

If I take result of percorso method I have error in; cordinate* per1[SO_HEIGHT * SO_WIDTHS] = percorso(ts, cord, mat,a);

Sry for very bad english

No idea what you're doing here, but you can return result* only

No idea what you're doing here, but you can return result* only

I'm creating a method for move a taxi in a map. I want to return the coordinate x and y of all calculated trip

So i can insert this value and move the taxi

No idea what you're doing here, but you can return result* only

This give me error

Hello guys any tips for learning C and books to read?

thank you so much king

in c++, If i initialize object variables outside the constructor, will it be equivalent to do these operations at runtime, "manually"? For example, for this class: class AClass() { public: AClass() { } private: int t[16] = { 0,0,0,0, 0,0,0,0, 0,0,0,0, 0,0,0,0 }; int n = 0; int p = 0; [...] // class funcions }

It will convert it to the default constructor with init list that does all of the above

good. for what i am doing now, just a few random things will be inside the constructor, so they are initialized at runtime when each object is created. thank you! (:

Init list and constructor does all its things at runtime unless it is constexpr context

The only difference is "when"

Init list is executed before getting into the body of the constructor

great!

i have a few defines for this class, but i am not sure it would be a nice idea putting them as constants in the object. would not that occupy more space than how defines are used, which can be contained in many CPU instructions?

Ever learnt what static's do? :P

class Foo { static constexpr int bar = 42; };

Ever learnt what static's do? :P

yes, i have, long ago - i forgot exactly what it is. so, i refreshed about it here: https://www.geeksforgeeks.org/static-keyword-cpp/ And static variables or properties would not be good here.

class Foo { static constexpr int bar = 42; };

mmm... constexpr together with it?? (( reading: )) https://stackoverflow.com/questions/13865842/does-static-constexpr-variable-inside-a-function-make-sense

And why so?

Are you just fond of storing constants in EACH object for no reason?

"And static variables or properties would not be good here" : because the objects have a few things that are based on fixed numbers, but their properties are not a copy of them. Based on them, but not a copy.

Are you just fond of storing constants in EACH object for no reason?

no, no! i am not storing constants for each object. there are "constants" that have a fixed value for one object, but this fixed value is not necessarily equal for all the other objects of that class.

Then make them const and initialize in the init list

mmm... const properties can be changed by an object instance at runtime?

No. You assign it once on creation of an object

Hello. How i must make copy constructor for a struct with anonymous union?

Thank you

Hello. How i must make copy constructor for a struct with anonymous union?

We're talking about C++ right? Is it exposed outside of your struct? If not, you should know currently stored in union type inside the struct?

Maybe i have wrong architecture, but it described in outside table. Struct carries index for this table. So than i must address to this table and get type. Just binary copy would be ok =\

Can you show the code of your struct?

I use this structs only for data encapsulation, nothing more. struct Device::Value { const char* const as_string; union { uint8_t as_byte; union { int32_t as_int; uint32_t as_uint; uint8_t as_array[4]; }; union { uint16_t as_word; struct { uint8_t lsb; uint8_t msb; }as_bytes; }; }; ~Value(){ if(as_string) { delete as_string; } } };

Yeah it hard shitty coded =)

I'm not 100% sure, but you probably can put your union into another struct and just copy it in your copy constructor

Pls note it is undefined behavior
