ZADANIA Z predmetu PROGRAMOVANIE

[profesionale]

Mam problem pri kompilovani na omege.

Ked dam skompilovat tak mi vypise zopar warningov.

Napr:

./main.c:27: warning: implicit declaration of function âfacingEastâ

a tomto riadku mam

Code: [Select]

if(facingEast())
{
int turnBack();
}
else if(facingSouth())
{
int turnRight();
}
else if(facingNorth())
{
int turnLeft();
}
if(!frontIsClear())
{
turnLeft();
while(frontIsClear())
movek();
turnLeft();
}
else
{
while(frontIsClear())
movek();
turnLeft();
movek();
while(frontIsClear())
movek();
turnLeft();
movek();

}
}
definovanie funkcie je tu

Code: [Select]

int facingSouth()
{
  if (karel_direction == 270) return 1;
    else return 0;
}
Neviete nahodu co ta chyba znamena lebo nikde to neviem najst. Dakujem

[psicho]

ma include na library.h ?

[profesionale]

tak teraz mi zase vypisalo toto

a moj library.h vyzera takto

#define MAX_WIDTH 20
#define WALL -1
#define EMPTY 0


int karel_beepers = 20;

int beepS = 1;

char * smer();


// aktualna poloha robota

enum Direction {
     EAST = 0,
     WEST = 180,
     NORTH = 90,
     SOUTH = 270

struct World {
  int width, height;
  int data[MAX_HEIGHT][MAX_WIDTH];
};



[psicho]

boze boze to mas zleeeee

[swam]

pocujte ludia...mam taky mensi problem z tou vymrdanou omegou...skompilujem svoj program,secko v poho spravi..a dam spustit karlika a mi to nerobi pekne po kroku ale vykresluje kazdy jeden jeho pohyb jakeby screenshot...takze mam za sebou obrazky kazdeho jedneho kroku co spravi...heh,pricom vo funkcii draw() mam ten system("clear") na premazanie obrazovky...neviete niekto kde este moze byt chyba???

[profesionale]

prosim ta a co tam mam zle....mohol by si mi s tym pomost. Prosim ta.

[psicho]

ta vsak rob podla cviceni ni ?  tam to mas presne

no v podstate musis dat do .h deklaracie vsetkych funkcii ktore xes vydiet mimo .c suboru ...teda v inom zdrojaku

a do .c davas  definiciu potom tych funkcii a ked mas len vramci jeden kompilacnej jednotky funkcie tak ich deklaracia musi byt uvedena vzdy pred ich pouzitim , lebo C compilator je lenivy a nexesamu X krat prechadzat ten isty zdrojak

[profesionale]

cize z main je include iba na library.h z library.c volanie na library.h nieje a teraz mi ta posahana omega hadze toto:

Pokial som to pochopil tak netaha define.vsetko ostatne natiahne. Teraz nechapem. Ako programujem weby a vzdy som si myslel ze najhorise je spravit kompatibilitu pre IE, Firefox, Safari a podobne....ale vidim ze som sa zmylil.....omega prekonala....

tazko povedat, ze co to znamena, ze co to znamena, ze jednoducho vobec nejde na tej omege. ak som dobre rozumel - pouzivas ncurses funkcie? vo windowsoch prikladas do projektu pdcurses? kompilacia pod linuxom ti zbehne? nezabudol si tam pre prekladac nechat poznamku, ze ma pouzit aj ncurses kniznicu (-lcurses)?
.. poviem to takto... mam obycajneho karla (bez curses) ten mi ide vo wine aj na omege(bez system("pause/cls") ).. potom mam karla s curses vo wine ide vsetko v pohode... ked ho ale prerobim do linuxu (takym istym sposobom ako toho "obycajneho" karla).. tak kompilacia prebehne vporiadku ale vysledny program nefunguje --> tj vykresli svet a pod neho jeho polku a dalej nerobi nic... a sposobi to este to ze cele putty sa mi bugne .. cize stale to vypinam zapinam ... spravil som taky "pokus" ... ked som toho "linuxoveho" curses karla spustil vo windowse tak isiel tak ako mal (hoci tam preblikavalo, ze nepozna prikaz clear).. tak uz fakt neviem co to chce

[tommy-sv]

nejaký fajnový debuger na C .. (windows.. devcpp pripadne iný)kde by som mohol vidieť obsah premennej ,hodnoty nadobudnuté na aktuálnych pozíciách v programe ..atd ..{skusal som gdb +dev ak by ste vedeli o niečom ++ ;w}

Zrejme nepoviem novinku ale ked Windows tak zeby Visual Studio? Ja by som pre C/C++ nevymenil za nic ine.

ludia pls, co tu mam zle v tejto funkcii? v maine mozem napisat ako prvy ktorykolvek prikaz okrem movek() a vsetko ide ok ale ked dam movek() tak mi to nechce nacitat vobec subor vypise mi chybu pri otvarani a uz som z toho na nervy...pls help

No ja sa bojim ze to asi nedas dokopy....lebo usleep je to iste ako sleep ale s tym rozdielom ze uslep je na unix. Pri windows sa do sleep udavaju ms tak pri unixe su to sekundy.

no ked som to prepísal na sleep, teraz už kompiler nič nevyhadzuje, problem ,je že to beží strašne rychlo a pritom vypisuje nejake error

usleep() pracuje s mikrosekundami ak ma pamat neklame (neklame: http://www.opengroup.org/onlinepubs/007908799/xsh/usleep.html), a este napr. Microsoft C run time nema sleep(int neviemakecesonds) ale Sleep(int miliseconds)

[Palike]

ako spravim tuto funkciu?..

void setStepDelay(int) - Sets delay of one Karel's step in miliseconds.

skusal som nieco take..

void setStepDelay(int e)
{
sleep(e);
}

ale nejak to neslo

ok.. ked uz ma vsetci ignoruju  mozno cez video vam to bude pohodlnejsie http://www.screentoaster.com/watch/stUEtdQkVLRFtYQ1hVXVJRV1dc

[ursus]

omg ved, vsade kde mas sleepy v tych funkciach kde ho treba, das miesto coajvem sleep(500), sleep(e) a toto e budes fciou setstepdelay menit

[mirek]

ok.. ked uz ma vsetci ignoruju  mozno cez video vam to bude pohodlnejsie

vazne uz mam lepsiu predstavu o tom, co si sa snazil opisat akym sposobom mazes obrazovku? lebo pri pohlade na to blikanie by som povedal, ze volas dakde system("cls/clear"). alebo pouzivas ncursovsku funkciu?

[Joey_XD]

Kto mi vysvetli jednu vec.... Na ubuntu mi ide Karol perfektne, riesi problem ako ma... Ale ked skopirujem tie iste zdrojaky na omegu, prelozim cez make (preklad prebehne bez chyb), lenze pri spusteni programu Karol v jednom okamihu zastane a vypise ze narazil do steny, aj ked uz cez to niesto presiel predtym.... Uz fakt neviem co s tym je... v algorytme by nemala byt chyba ked na ubuntu to ide bez chybycky.


a to som este zabudol, ze pri tom kroku co zastane je podmienka if(frontIsClear){movek()} ... cize nechapem

Zavolame na omegu Foxa Muldera a Scullyovú

Robi to este niekomu?

[revelc]

asi ti to nepomoze (mozno si to len zle prepisal) , ale nema tam byt?

if(frontIsClear()){movek()}

[potototamto]

ako mam zadefinovat ten postup beeprov, aby mi vypisal zaradom 123456?...mne to hodi na kazdy druhy krok...zadanie 11.

[Vikinger]

zadanie 11 uz tu bolo hodene takze len pohladaj a nespamuj :-) je cele spravenee tak len sooosujj:D
