Molim vas da mi objasnite sto i kako rade,sto uzimaju,sto vracaju i u kojim su datotekama definirane ove funkcije:
rand i srand
strtol,strtod
toascii
frexp
clearerr
setbuf
void qsort (void *base,size_t nitems,size_t size,int (*compar) (const void *,const void *));
void *bsearch (const void *key,const void *base,size_t nitems,size_t size,int(*compar)(const void*,const void*));
Unaprijed veliko veliko HVALA!

[tt]rand()[/tt] vraca "slucajni" integer izmedju 0 i [tt]RAND_MAX[/tt]. :)
[tt]srand(unsigned int seed)[/tt] sluzi za inicijalizaciju generatora "slucajnih" brojeva, u ovisnosti o parametru [tt]seed[/tt]. :)
[tt]long int strtol(const char *nptr, char **endptr, int base)[/tt] i
[tt]double strtod(const char *nptr, char **endptr)[/tt]
pretvaraju string [tt]nptr[/tt] u [tt]long int[/tt] odnosno [tt]double[/tt]; preko pointera na pointer na znak [tt]endptr[/tt] vraca adresu prvog znaka u stringu [b]iza[/b] broja. 8)
Ostale potrazi s naredbom [tt]man[/tt] na nekom Linuxu. 8) Mozes i na HP-UX-u (cit. na studentu). ;)

TOASCII(3) Linux Programmer’s Manual TOASCII(3)
NAME
toascii - convert character to ASCII
SYNOPSIS
#include <ctype.h>
int toascii(int c);
DESCRIPTION
toascii() converts c to a 7-bit unsigned char value that fits into the ASCII character set, by clearing the high-order bits.
RETURN VALUE
The value returned is that of the converted character.
CONFORMING TO
SVID, BSD
BUGS
Many people will be unhappy if you use this function. This function will convert accented letters into random characters.
SEE ALSO
isascii(3), toupper(3), tolower(3)
GNU 1995-09-16 TOASCII(3)[/code:1]
Sretno! :D

Takodjer, OBJASNITE sto vas muci! "Sto mi je krivo?", bez opisa u cemu je problem, rijetko ce zadobiti moju paznju.  |
