1 1 2 1 1 3 3 1 1 4 6 4 1 Can it be printed using a loop?

First line is 11 I think

Ah 1 then 1 1 the 1 2 1

for(int i=0; i <= max; ++i) cout << pow(11, i) << endl;

for(int i=0; i <= max; ++i) cout << pow(11, i) << endl;

It will print the list

for(int i=0; i <= max; ++i) cout << pow(11, i) << endl;

How is it in C?

printf("%f\n", pow(11, i)

You have an obligation to ask straightforward, specific questions that fully address the heart of the problem

i need compare two datas, but it's one iterator..... do i need use overloading operator like <=?

Clarify what you need to compare. Data or iterator? Bidirectional Iterators can be compared as is. Data from iterators can be compared as (*it1 < *it2).

um my fuction return data like that std::vector<value_subject>::iterator

and then I use auto x = namefunction(data)

and then I compare if (x->value > y->value)

and then I compare if (x->value > y->value)

How to get the value from subject? value_subject x; val = x->value; ?

yep

yep

try if (*x->value > *y->value) it should work in my mind

try if (*x->value > *y->value) it should work in my mind

i tried but it doesn't work

Ok. Waiting for more skilled guys

I figured out the problem

try if (*x->value > *y->value) it should work in my mind

It should be if ((*x)->value > (*y)->value) This would only work if *x returns a pointer or a class instance that has overloaded operator->. I am assuming that is the case here

I don't understand your situation

Is it possible to locate a guy's location with c++ using his/her ip address?

Idk but you could get infos about socket libraries

so all tcp packs has metadata about start of route and end.

Is it possible to locate a guy's location with c++ using his/her ip address?

First of all, the IP address you get may not be actually the person's IP address unless you are establishing a direct connection to his computer. Most often the IP address you see will be that of an ISP remote hub (a NAT service provider) or maybe a VPN service provider. And with that IP address you can use Geolocation APIs to locate the IP address.

I got it.

So the structure of an ip address from vpn,proxy or dns can not be even a little bit as same as that person's actual ip adress.

If I connect to a VPN service provider in Switzerland from my home in Africa, the IP address will be of the VPN provider in Switzerland.

dunno, it might be possible

I doubt that you can easily get it tho... i think it's implemented via lookup databases

well but i wouldn't consider this as "getting location via c++" this is getting it from google api

Yes. That is what I suggested earlier to him. I suggested using some API instead. The C++ standard won't provide some facilities for this. Neither would the OS. You have to definitely use some 3rd party API

since c++ is compiled it can be more fast, but under the hood python functions are c/c++ so with libraries like numpy python is only a glue between c++ calls (so it won't be that slow)

hi, I'm reading "The C Programming Language" and this phrase is not 100% clear for me:

"In the absence of explicit initialization, external and static variables are guaranteed to be initialized to zero; automatic and register variables have undefined (i.e., garbage) initial values." what are automatic variables?

"In the absence of explicit initialization, external and static variables are guaranteed to be initialized to zero; automatic and register variables have undefined (i.e., garbage) initial values." what are automatic variables?

variables created with auto, for example: http://web.archive.org/web/20130927234242/http://itee.uq.edu.au/~comp2303/Leslie_C_ref/C/CONCEPT/storage_class.html

"In the absence of explicit initialization, external and static variables are guaranteed to be initialized to zero; automatic and register variables have undefined (i.e., garbage) initial values." what are automatic variables?

In C, auto and static defines the behaviour of the variable lifetime

Precisely Because of the combination it's hard to get a result.

Hello. I'm trying to implement Server and Client app in C The server must be able to handle multiple clients at once. The main task of the Server is accepting numbers from Clients and processing them. The server does not respond to clients but only works as a receiver. I'm new to socket programming and don't fully understand how to implement it correctly. But I read that when processing data from clients, it is better to use select (), and not threads. Is it so? What about multiprocessing + select()? Where can I read this without going too far into the theoretical basis. Where can I see realizations of productive servers?

Why you not use push_back() instead of assign the temp vector ?

I want to find max value in the subarray temp actually 😅

i'm truly, why do you do so?

you could sort just using iterator

sort(vec.begin()+2, vec.end());

I want to find max value in the subarray temp actually 😅

possible reason for segmentation fault not returning value. when you create vector temp the inner array located in class vector could be lesser then 3 and that's why you just tried to get access to memory which isn't available for you program the easiest way to check my suggestion vector<int> temp {0, 0, 0};

in this case the size of inner array in std::vector will be exactly 3 have fun in leetcode :)

example

std::vector<int> data = { 10, 9, 8, 7, 6}; std::vector<int> ::iterator it; it = std::max_element(data.begin() +2 , data.end()); std::cout << *it;
