Umm... I have a question.(C) 1.Why can't an array be assigned value after being declared? 2.Is it necessary to initialize the array while declaring to store value in it if I don't want to use strcpy ()? (Just wanted to know if any other way existed) 3. (Last question) Can I declare and initilaize an array inside a decision control box? Thanks in advance :-)

In case of 'char' ?

1. what do you mean can't be assigned a value after being declared?

2. no, you can store values in the array without initializing it during declaration with a for cycle, as long as you fill all and only the slots allocated to the array, otherwise you will read garbage data or access forbidden memory

Can you please be more elaborate. Sorry for troubling you.

for (i = 0; i < ARRAY_SIZE; i++) { array[i] = someValue; }

this fills the array with the variable someValue without you having to write the initialization fully

O i get it Thanks a bunch

#include<stdio.h> #include<stdlib.h> struct array { int A[10]; int size; int length; }; void display (struct array s) { int i ; for(i=0;i<s.length;i++) { printf("%d ",s.A[i]); } } void append (struct array *p,int x) { if(p->length<p->size) { p->A[p->length++]=x; } } void insert (struct array *p,int index,int x) { int i; if(index>=0 && index<=p->length) { for(i=p->length;i>index;i--) p->A[i]=p->A[i-1]; p->A[index]=x; p->length++; } } int main() { struct array s={{1,2,3,4,5},10,5}; insert(&s,3,7); display(s); return 0; }

will this be better way of inserting array

or without using pointers and structure would be fine?

Element to array*

I'd use dynamic array

list with malloc, allocate a block of memory one time

O i get it Thanks a bunch

mind you, ARRAY_SIZE is not a const int in C, it has to be a define or a number iirc

in C++ you can use a const int

Well, you can if you have c99 or up

Even more so, you can use VLA

Well, you can if you have c99 or up

yea right

I assumed c89 for some reason

they thought us strict standard c89

so it stuck with me. It's always a wonder being able to use // for line comments or declaring indexes inside for loops

Ok..sorry...i just wanted to help..

And you're a pathetic troll!

You should be flogged 260 times

With no rest

And should made to compile a large C++ code base by making the assembly with Notepad, while your legs are tied with your earpiece!

Same in Brazil, Java is only rivalled by C# on Microsoft platform. C and C++ are mostly used on embedded systems companies.

The only place Java is not used is in nuclear power plants.

ewww java

I do not make the TIOBE index. If people could choose instead of following market demands, what language would they elect? Or what tools will they use for personal projects? 🤔

Idk. people want easy money

This group is trash .. Nothing to lean or gain here .. No coding, no programing or c++ related issue

I agree somehow. We should have better issues than just the standard how to learn C++ beginner stuck where the answer is always the same

I created a C++ experts group. I wanted to send the link... how can I share it now?

its here already, no?

we already have one

you should’ve asked lol

hold on

Bruh... xD

Where can I see my warnings and how many I've left?

Oh damn.. 😅

I was asked in the interview, about what to take care of when trying to send a struct over a network, between a windows and Linux machine, assuming that the receiver knows how it is structured. I answered on care in 32/64 bit data type difference, big and little median. But the interviewer seem to expect more... could anyone elaborate?

Os might provide library function transfer between host byte order and network byte order, like linux htons

padding

Also alignment

But I assume that the struct always comply to memory alignment automatically isn’t it?

But it doesn't mean that they will match on different pc's if you send it via network

Oh, you mean one can interpret the bytes differently? I didn’t read about this details🙈 but I get to know that the memory padding on struct might work differently on different compilers.

Are you talking about endianness?

I mean that the sizeof of an unpacked struct could be different

On different machines

Hi

i have a vector of union. if i want to iterate and print all values. how can i achieve it?
