If I compile program in normal way, will maximum heap size be limited by RAM?

It depends on OS, compiler and compiler options, I think
Mostly on OS and how it manages the RAM

Why are you asking? Just curiosity or you faced a problem?

Just decided to write own malloc/realloc/free

Just decided to write own malloc/realloc/free
I think googling jemalloc can help you. It's open-sourced memory allocator by Google

I hope you decided to do it just for learning

C programming for even numbers upto 100 which r multiples of 7
for (int num = 14; num < 100; num += 14) { /* output */ }

Depends. 2-3gb for x32 i think

Can be another reasons?
Some people don't like using libraries and write their own, because they think that they can do it better
In most cases they can't

they can in fact (perhaps there’s one exception called me) :)

hello one question , if i have a pointer to an array given in input to a function ... lets say: void (int *) ; is it possibile to determine the size of the array insiede the function , or i need the pass the value to the function as input?
Al
sorry i miss the name of the funciont : lets say: void myFunc ( int *)

no that point to the starting point of an array

With bare pointer you can't determine the size of an array
Al
ill pass to the function the starting point of the array
MᏫᎻᎯᎷᎷᎬᎠ
Al
yes i suspected that
Al
thanks a lot guys
Al
ill work with array then
Anonymous

It is still is not a pointer to an array. A pointer to array looks kinda like this:
int (*)[10]
Al
or i will pass the size in a separate value
MᏫᎻᎯᎷᎷᎬᎠ
No, you can't
The bare pointer passed to the function Don't have any related meta-data that determine the size

Type of pointer to array of 10 ints
Al

MᏫᎻᎯᎷᎷᎬᎠ
Unless you use std::array
Al
then i can p++ to scan the array
MᏫᎻᎯᎷᎷᎬᎠ
Or using templates
Al
is C no C++
MᏫᎻᎯᎷᎷᎬᎠ
There's no such way
But you can pass size argument to the function
Anonymous
Or you can define a struct
MᏫᎻᎯᎷᎷᎬᎠ
I think that how functions in C deal with collection of data
Al
Or you can define a struct
yes thata snoter solution but in this specific case im kinda obliged to use an array
Al
sorry for typos...
MᏫᎻᎯᎷᎷᎬᎠ
yes thata snoter solution but in this specific case im kinda obliged to use an array
Then there is no way, except to pass the array with size variable
Al
That keeps track of the array size, nah I think not
no i think he was suggesting to NOT use the array but to change it into a struct
Al
thank for helping !

sorry, we aren't in c++
That's literally what I'm talking about
It's annoying to do this
Array ar;
ar.elems[0] = 1;
ar.size = 1

You can use that struct as an array_view

That's what I was talking about

ar.elems[1] = 7;
ar.size = 2;
Looool

But again I was talking about other usage
C.
??
You can't write methods in C
You kinda can. There are some crazy people that make C Obj oriented with structs and such

Yes I've heard about it
But it is so weird and ugly

Yes I've heard about it

It uses undefined structs. It's strange,

i asked someone before if there was an way to find the length of a string in C

i was given a for loop , lol

makes sense , if its not the null character( the end of the string) keep on counting up lol
