<0> lol
<1> so can some1 tell me why it doesnt help
<1> i mean work
<1> why doesnt it work
<0> yea just a sec
<1> ty
<2> g-gao: I just did. but you didn't have the basis to grasp it. you need to learn more about data-types before you start doing things like that.
<2> g-gao: first, read this: http://www.catb.org/esr/faqs/smart-questions.html
<1> ....
<1> codecaine
<1> can u help me
<2> you need to help yourself
<0> take and & sign off the x in the prinf statement
<0> printf doesn't read address like scanf
<1> yep but when i type a huge number it doesnt work
<2> that's because there's no room for it
<1> then how much can it fit
<3> In an int? sizeof(int)*CHAR_BIT bits, probably 32 bits
<2> 4294967295 is the biggest number you can fit into an unsigned int
<1> whats with the 32bits thing
<2> divide that by two and you have the biggest number you can fit into a signed one
<3> printf("%d",&x); is very wrong
<1> isnt 32 bits 4 bytes = 4 characters
<2> aha, and, you're printing the address of the variable, not the content.
<3> Numbers are stored in binary, not decimal digits
<2> g-gao: yes, that would be correct but you must put some meaning into it other than that
<1> what do you mean?
<2> I mean, what do you do with this info other that state it?
<2> s/that/than/
<2> stating
<1> nothing i just wanna point out that something is wrong with scanf()
<4> (: hi
<2> no, that is incorrect, you need to learn how things are affiliated
<3> Nothing is wrong with scanf(), you don't understand some fundamental concepts
<0> yea
<1> what fundamental concepts?
<3> Data storage apparently
<2> g-gao: the concepts of not being a moron.
<2> oops
<2> that just popped out
<2> g-gao: google c data types.
<1> ok
<1> so which one do i go to
<2> LOL
<3> Just read a C book, please
<5> t for troll anyone?;/
<2> I think you should go to your mommy; seriously.
<2> yeah, this is beginning to look like a troll :)
<1> yeh a troll what a loser
<1> no im not a troll i just want to know why scanf() and printf() wont let me use a huge number.......
<3> Because the number does not fit into an int
<1> then what can it fit into?
<6> it might not fit into anything.
<1> what if i want to work with a really big number...
<3> Would 64 bits be enough for you? If not, it won't fit into a single "variable"
<6> then you are fooked.
<1> 64bits?
<3> Then you use gmp
<6> at least as far as using standard c.
<1> 64 bits is how many numbers
<6> you'd need a "bignum" library.
<1> i mean digits
<6> lots.
<1> i thought 64 bit = 8 byte = 8 characters
<6> uh.
<3> Numbers are not stored in decimal digits in memory
<7> 64 bits = 18446744073709551615
<3> They are stored in binary, so it goes up to 2^64-1 which is a lot
<6> at least not so far as c is concerned.
<7> 18,446,744,073,709,551,615
<1> so numbers are different?
<7> 18 bizillion
<3> Different from what?
<1> characters
<1> like "a"
<1> coz i know a is 1 byte
<1> i read it somewhere .. each character is made up of 8 bits
<3> Characters are numbers too, and these numbers represent a character
<3> '0' is 48
<0> 256 for ascii
<6> "a" is a string literal.
<3> Just read a C book please, it's all going to make sense
<1> i dont have a c book
<6> 'a' is a character constant, with type int.
<0> theres ton online
<1> yeh but ive read like 3 tutorials and this hasn't come up
<7> quintillion
<4> bad tutorials
<1> can someone lead me to a good one please?
<1> that explains all this?
<1> and how data is stored in bits and how many u can store
<4> google can
<6> i too suggest a book.
<6> calc k&r2

<1> i dont have the money to buy a book o
<6> borrow it from a library.
<1> i can do that?
<2> I know a good online book
<3> Surely there are libraries around?
<4> borrow it from a online library
<1> can you tell me it plz mrMister
<2> but I dont remember the link :)
<1> ....
<4> try to google
<7> calc tutes
<8> how would I know ?

<0> lol
<1> plz i need a good guide
<1> ints and floats are often 32-bit, chars 8-bit, and doubles are usually 64-bit. bools are often implemented as 8-bit data types.
<1> what does 32 bit mean
<1> i dont get it..
<1> how much can u store in 32 bit
<3> It means it takes 32 bits when in memory
<1> yeah 32 bits
<1> in the memory
<9> you can store 2^32 different values in a 32-bit variable (roughly 4 billion)
<9> 32-bits -> 4 bytes (on most computers)
<1> yes
<3> You can store 32 bits of data, 32 times 0 or 1. You can either use that for a single 32 bits number ( 0 to 4 billion ), 4 ASCII characters, a float with a mantissa and exponent, and so on
<1> oh i see
<3> Don't mix up integer variables stored in binary, and ASCII characters...
<1> yeh :p
<1> wow thats a lot more
<1> so 0 takes up how many bits in binary
<9> g-gao: depends upon what type you're storing 0 in
<9> are you storing 0 in a char? in a short? an int? long? float? double?
<3> Any number of bits can handle zero. Well, at least one bit that is
<1> an int
<9> an int is typically 32-bits.
<3> An int is sizeof(int)*CHAR_BIT bits no matter what you put in it
<1> if you can store roughly 4 billion in an int then howcome it can only print back a few digits
<9> int myint = 2000000000; printf("%d", myint); // should display 2 billion
<0> how I have to try c with gcc
<0> you can use like grep and crap too
<0> :p
<9> on a typical compiler, an int can represent -2 billion to 2 billion, since that 4 billion different values needs to be split between negatives and positives
