as it states "Long code snippets", and his code is like what 10 or 20 lines?

in this code error is b.func not in the scope

well, its debatable if his case violates the rules

What is debatable?

What is debatable?
its still in the same sentence, does not explicitly state that the "long code" thing doesnt apply on that

oops same

why are you so mean? to me just trying to help, aswell as him.
ask yourself whats worse, someone asking "please hack facebook" or him actually asking a question that isnt completely made up..

Why we using pointers
A function can modify the objects through pointers, which is not the case when they are passed by value

Hi guys, can i ask you about something in algorithms and data structures ?
︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎
I don't get the concept of tail recursion and non-tail recursion, what is the difference between them ? Thanks guys
Francisco

It's not C/C++ related and it's also easy to look it up on Google. Tail recursion can be converted into a loop, non-tail recursion cannot

tail recurtoin is not using the context of self-call except via parameters and hence the previous stack frame of this function can be collapsed and replaced with the next call's frame of the stack, so, all recursion consumes only size of one frame on the stack.
if the recursion is not tail -- we must keep the prev. frame for the function to continue doing something after self-return, so, this will eat stack memory.
Tail recursion is NOT optimized in C or C++, so for C and C++ this doesnot matter

The last sentence is not true. GCC and clang are totally allowed to transform a recursive function into a loop
Ilya
Francisco
It really depends on the optimizer and the function itself, but compilers are allowed to do those kind of transformations to the code
Francisco
In fact, to see how crazy compilers can go optimizing, there's examples where clang can convert a O(n) function into a O(1) function
Francisco
Or a several lines function converted into a single instruction

sorry i try and format it

and get almost to the end and it gets a bus error 10

this function is apart of a larger program i am building

StringorInt StringorInt;? Same type and variable name

StringorInt is a enum, and the second one is the variable name

Lol that union
use is able to choose if they dynamically make an int array or string array,
Francisco

Isn't it a compile error to name a variable just like its type? if it isn't, then it surely is a bad thing to do
Dima
just use void* lmao

bad practice (not for me) but you can use void*

it compiles and gather all the data required , but then when its time to allocate the memory and take it the actual members of the array from the user, it get a bus error
Francisco

Well, it compiles with clang, but not with gcc

Well, it compiles with clang, but not with gcc
the full program compiles in gcc , i have the latest version also
Francisco
you probably need the full program
It doesn't matter. The snippet he showed compiles with clang but not with gcc
Francisco
Anyway, I'm pretty sure that code wouldn't pass any revision anywhere

what causes it
Francisco

I've researched a little bit and it turns out you can't do that and it's a bug in any compiler that accepts it
Anonymous

so i need to change the variable name ?
Francisco
Obviously? You should never name a variable the same as the type, even though a compiler can accept it
Francisco
I don't know if that's the bug, but I'm pretty sure it's the right thing to do
Anonymous

yea i changed it , but thats not the bug
Francisco
Run the code through a debugger or through valgrind. I can't tell you no more. Your code is messy and hard to understand, and I don't feel like doing it
