Question

hey osanseviero! :)
here are some stupid questions:
explain what void and int means.
and put it dumb terms

Answer 1

Lolz... Well, i suppose you refer to c++ or C...because void has lots of meanings.

Void: It means "nothing" or "no type". In a more "complicated" way, it means that the function doesnt return a value.

Int: I will tell you in an easy way. Int represents integer numbers.

If you are not sure with void, read this ;)

Answer 2

yes oops c++ lol

Answer 3

ok int is easy to understand

Answer 4

i know what an integer it lol

Answer 5

now void i don't know what the point is to do voids

Answer 6

oops i forgot to paste the link, wait a sec

Answer 7

lol

Answer 8

it is harder to explain, but it is when the function doesnt gives you a value

Answer 9

you know after it said read this i reread the paragraph because i didn't know what else to read lol

Answer 10

lol sorry

Answer 11

void bresLine( blah blah)

doesn't return anything

is this just defining the parts that will be used later
i think i get it
thanks so much
you are truly awesome

Answer 12

lol thanks :)

Answer 13

err void means more like there is nothing returns from that func(i mean a func defined as void) ,, or you can use
functype funcname(void) as u want to say no parameteres in this func ;)
for example void cls(coid) ;)

Answer 14

sorry korcan i don't think i can help you with yours :(

Answer 15

just think it like that void funcs does not get a return value, for excamplue we have a func named Summation(x,y), it does return x+y, but for a func like CLS (clear screen) it likes that CLS(void) and it only clears screen it does not return a value, so you can say its a void func ^.^ but summation is not

Answer 16

u mean my X86 Assembly question?

Answer 17

yes

Answer 18

np man, but u shuld start to work on X86 assembly too, i been working on programming 2 years, (since i was 12) learned Java, QBASIC, VB.NET, C++, C#,C , developed over 4 games in C#, XNA (like tetr 2D games) and solved over algorithm questions, but once I started to work on X86 ASSEMBLY i see i know nothing :P and got shocked -.-'

Answer 19

*** solved over 6.000 ....***

Answer 20

wow i'm a beginner

Answer 21

lol

Answer 22

if i had a chance, i would make myself begin programming with X86 Assembly :P

Answer 23

how old are you?

NULL and void may have different meanings in Law, in Math, and in C and it's derivatives. Void is generally used in 3 places in C (in the other languages they might not have such a use or are optional):

They are placed in place of function arguments:-
int foo(void) /*foo will not accept any arguments. In C++ (not sure about java)
you can just have int foo() since void in that case would be optional */

They are also used when specifying a function's return value:
void foo(int bar) /* foo will never return a value */

Also, they are used to declare generic pointers that point to objects of unknown data types:
void *foo = NULL; /* Note that in the standard it's illegal to dereference a *void
pointer without casting it to a proper type */

Sometimes you don't require a return value from a function (like printf for example, even though it actually returns an int IIRC.) Casting it as void is a polite way of saying that you don't want to use the functions return value, forcing it to return nothing.

If the operating system you are programming for can't return a value, declaring main to have a void return type would be the polite way to do things (people will want to hurt you if you declare main with a void return type if the system can deal with main's return value though so unless you know what you're doing declare main with an int return type (C) ).

Answer 25

I guess you know what int means :-D general type for an integral value.

Answer 26

integer*

Answer 27

integral values are integers anyway :-D

but you have so many kinds. char, short int, long int, long long int...

Answer 28

and then there's unsigned/signed.

Answer 29

yeap ^.^ err well we can2t say all the integral values as integer, they can be sometimes float :D

Answer 30

thank you guys for all your input
