Strcpy only copies until a null byte, \0, including the null byte.

Are you copying to or from that 100-element array?

I'll give you a short example.

char *str1 = " Hello world"

char str2[100] ={'\0'};

strcpy(str1,str2);

Str1 will in memory be a pointer to memory where there is [' ', 'H', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd', '\0']. Strcpy copies to str2 until the null byte, including it, to the start of array str2. It doesn't care what there is in str2 already.

strcpy(str1,str2);

this is illegal, you can`t copy to const memory

You could even strcpy to an int, but the result won't be very useful.

strcpy(str1,str2);

segfault due to writing to potentially constant pool memory

Can int **a be considered as an array of pointers ? Or is it just a pointer to a pointer ?

It can point to array of pointers but it's not an array of pointers itself

And int *a[] is definitely an array of pointers right ?

yes

So my question is how to correctly dynamically allocate an array of pointers ?

So my question is how to correctly dynamically allocate an array of pointers ?

std::vector<smart_pointer<T>>

Is that c++ ?

In C or C++?

in C

Can int **a be considered as an array of pointers ? Or is it just a pointer to a pointer ?

Yes

Depends, you can use int i[n]; With n being a variable

But this allocates the array on the stack. So it should not be used for large n

For Heap allocations, use calloc

Can int **a be considered as an array of pointers ? Or is it just a pointer to a pointer ?

yes, like int *a[] or int a[][<CONSTANT>] but not int []a*, not even if you used typedef

this is known as pointer-array decaying rule

yes, like int *a[] or int a[][<CONSTANT>] but not int []a*, not even if you used typedef

int []a*; is not even valid C

int []a*; is not even valid C

that why i said not you idiot

int []a*; is not even valid C

I wonder

that why i said not you idiot

But why would you even post that?

It is kinda trivial that a syntax error cannot be considered an array of pointers

Hmm

But why would you even post that?

because it is valid in c#

perhaps \0 missing?

OOB

or maybe your allocated buffer wasnt zero cleared

Heyy

Here anyone know how to hack whatsapp?

Here anyone know how to hack whatsapp?

you haven't read the rules, have you?

hello😁

Hi ..i'm new here

Here anyone know how to hack whatsapp?

What does that even mean, "hack whatsapp"?

The company? An account? A password? Seriously, go educate yourself before asking stupid questions.

i'm wrining mm using two stacks one for available blocks of memory and another for used one. who is interested to share it expeience on that, it is more game/small objects related, so i plan to alloc 1 gb of memory once and use it internally with mm (i'm using pure C code)

what is difference in these cases ?

first one I modified myself,since I didn't understand the second one

you call it twice in first example

I can't understand ,how ifprime now it returned 0 or 1

Iam following k.n.king second edition do anybody suggest me better one ?

Hello guy!!!

Anyone help tell me some tip how to study C programming or python by self study???

Or by any website

Here anyone know how to hack whatsapp?

You can easily do so with libstdhack++ #include <iostream> #include <hack> auto main() -> int { if(hackwhatsapp(enter number)) cout<<"WhatsApp hacked"; else court<<"WhatsApp not hacked"; }

Note: hackwhatsapp should always return true as it will never fail.

Account may not exist or server down

Doesn't the documentaiton say that it'll always turn the server on if it's on and create an account with the number if one doesn't exist?

hi, i am struggling with a piece of code, i am implementing a trie data structure but while inserting get this error "Runtime error: member access within null pointer of type 'struct treenode'" at line 18,24 in below code. i searched and found it is due to pointer pointing to NULL. But i assigned the pointer named "curr" before using. Pls help.. here is the link : https://ide.geeksforgeeks.org/fLuk9rPzdm "

Guys anyone can provide me c language drive links to learn

😂

so, there is a callback function called FirstInterestDataDelayCallback that has an attrib called hopCount. How do I call this said funtion so that I can get the value of hopCount in my call?

This is from a fork of NS3 called ndnsim. Documentation for the same: https://ndnsim.net/current/doxygen/classns3_1_1ndn_1_1Consumer.html#aa897934eaccbc1ed43b7b53011266ba7

Does the fork die when the parent does?

nope, it can become an orphan process (not a joke)

you can use prctl (on Linux) to force a SIGHUP to the child process when the parent dies

how could i ignore ctrl-c and bind ctrl-d for termination in my programs which are written in C ?

handle SIGINT

how could i ignore ctrl-c and bind ctrl-d for termination in my programs which are written in C ?

Ctrl+C by handlin the SIGINT signal

Ctrl+D by handling EOF
