Chlapci, prosím vás kuknite sa mi na to...

je to pre mňa nepochopiteľné...pauzujem to a ono si to robí čo chce...len to prebleskne a keď to debugujem dajak mi to píše bludy...pri kompilovaní mi chybu nenájde..

je smutne, ze uz poradne neznam C++, ale porad se mi tam nejake veci nezdaji

sice neni chyba, ale to continue tam je uplne zbytecne, ma tam byt jen strednik
while (cin.get() != '\n') continue; => while (cin.get() != '\n');

(*ps).fullname je to same jako ps->fullname

main je v tele tridy?
nebo nemas u funkci student:: ? Tedy nemas udelane ze metody patri do tridy?
neco jako konstruktor, destructor?

Kdyz programujes, tak si delej ladici vystupy. Vypsat treba vsechny promene, ale samozrejme jen u tech kde vys co tam ma byt. Kdyz tam je neco co neocekavas, tak vys ze chyba je nekde kolem.

sem se prehledl, nemas tam u metod/funkci student::, tedy funkce nemaji prislusnost k tride

a jeste, nemusis mit display1, display2, display3, staci jen u vsech stejny nazev display, je tam vlastnost C++, myslim ... eh nemuzu si vzpomenout:P

Sahal jsi na paměť, kterou jsi neměl alokovanou. Viz. smyčka while v getinfo().

#include <iostream>

using namespace std;

const int SLEN=30;

       char fullname[SLEN];

};





int getinfo(student pa[],int n);

void display2(const student * ps);

void display3(const student pa[], int n);



int main()

{

    cout << "Zadaj velkost triedy: ";

    int class_size;

    if (!(cin >> class_size)) cin.clear();

    while (cin.get() != '\n');

    student * ptr_stu= new student[class_size];

    int entered = getinfo(ptr_stu,class_size);

    for (int i = 0; i<entered;i++)

    {

        display1(ptr_stu[i]);

        display2(&ptr_stu[i]);

        cout <<"::::::::::::::::::::\n";

        }

Diks chlapi, kruci to není môj kód to je zadanie a ja som to mal dotvoriť... obvykle hľadám chybu sám ale teraz nemám čas musím toho stihnúť veľa lebo idem pondelok preč..:p
