Don't ask meta questions. In other words, don't ask to ask. Questions like "Does anyone know XYZ?", "Has anyone used XYZ?" or "Can someone help me?" are all considered meta questions because they don't specify what your actual problem is. These questions give the impression that you want people to approach you and offer their help as if they don't have any other work to do. Now doesn't that expectation make you look like an idiot? If you have a question ask it directly. You are more likely to get a response that way.

Specify the problem, that's what the bot is saying.

yeah, because you are spamming with unrelated question to this group. wake up

U can tell me i am new

Chaudhary: I have a silly question...buy still I am not getting it When we "." (Dot) Operator and -> (arrow) Operator. When we re accessing the elements of structure in c

When we use "." (Dot) and (arrow)-> in c while accessing structure elements

Basically -> does (*pointer). I think ... It's supposed to be just a syntax sugar

What do you mean by syntax sugar.?

And dot I guess For accessing specific data type in the structure Am I right?

To make syntax easier

Hi

Hi

hii

Hey

hello can someone explain to me maps/unorder maps ?

hello can someone explain to me maps/unorder maps ?

Unordered maps are hashed. Ordered use trees

Hi

I am curious, what made you write 'hi' here after reading and accepting the rules?

what is hashing tho

what is hashing tho

There is tons of material online. But basically it uses some maths to get new number, it is usually one-way too (since it reduces the data onto smaller bitsize)

Why it is not allowed in C++ to assign a c-string to an array of characters like in the code below #include <iostream> #include <string> using namespace std; int main() { string s("ABC"); char list[4] = s.c_str(); return 0; }

Why it is not allowed in C++ to assign a c-string to an array of characters like in the code below #include <iostream> #include <string> using namespace std; int main() { string s("ABC"); char list[4] = s.c_str(); return 0; }

Look into reference or just read what compiler writes to your but I guess c_str returns const char* and you variable is char*

Why it is not allowed in C++ to assign a c-string to an array of characters like in the code below #include <iostream> #include <string> using namespace std; int main() { string s("ABC"); char list[4] = s.c_str(); return 0; }

oh there is even more :D

Why it is not allowed in C++ to assign a c-string to an array of characters like in the code below #include <iostream> #include <string> using namespace std; int main() { string s("ABC"); char list[4] = s.c_str(); return 0; }

so: char list[4] allocates array and list is pointer to beginning of that array s.c_str() just returns pointer to the beginning of internal buffer of string object Your code might mean something like allocate memory then forget about it and access internal string buffer or it might mean allocate memory and copy data string buffer into it which plain array cannot do. So compiler is not happy

If you want to have modifiable independent copy of "ABC" then somehow copy data from string into list

If you just need to have handy pointer to const data use const char list* = s.c_str(); or let compiler to distinguish type automatically auto list = s.c_str(); maybe you will need to prepend const before auto i am not sure

Why it is not allowed in C++ to assign a c-string to an array of characters like in the code below #include <iostream> #include <string> using namespace std; int main() { string s("ABC"); char list[4] = s.c_str(); return 0; }

It would not be allowed in C either. C-style arrays are a bit confusing in that they automatically decay into pointers to the type they hold. But a pointer is not an array, and hence pointers cannot be assigned to arrays and vice-versa. Pointers are just memory addresses, arrays are memory spans with a compile time known size. This means that while arrays represent a resource with bounds and a strict lifespan boundary in its scope, pointers only represent the positional aspect of the array: where it is

Nope...explanation was wrong

Correct explanation is When we access using pointer we use arrow And by accessing the elements by reference we use dot

foo->bar = (*foo).bar

foo->bar = (*foo).bar

.?

.?

That's what he meant, and he's right.

foo->bar = (*foo).bar

Does not get what you are trying to explain

Does not get what you are trying to explain

foo->bar is equivalent to (*foo).bar... it gets the member bar from the struct that foo points to. It is indeed syntax sugar. If you're into eerie explanations, read the C23 spec for it: A postfix expression followed by the -> operator and an identifier designates a member of a structure or union object. The value is that of the named member of the object to which the first expression points, and is an lvalue.93) If the first expression is a pointer to a qualified type, the result has the so-qualified version of the type of the designated member.
