why is returning an int from a pointer crashing my app

[Milan Krejci]

pocet_prac=new int;
*pocet_prac=0;
std::vector <SD >::iterator i;
for (i=vec_prace->begin();i!=vec_prace->end();i++) {
from=(*i).vrat_from(); to=(*i).vrat_to();
doba_prac=this->spojDoby(doba_prac,from,to);
*pocet_prac+=((to+1)-from)/2;
}

int doba::vrat_pocty_hodin_prace() {
return *pocet_prac; //crashes but dont know why?
}

pocet_prac=new int;
*pocet_prac=0;
std::vector <SD >::iterator i;
for (i=vec_prace->begin();i!=vec_prace->end();i++) {
from=(*i).vrat_from(); to=(*i).vrat_to();
doba_prac=this->spojDoby(doba_prac,from,to);
*pocet_prac+=((to+1)-from)/2;
}

int doba::vrat_pocty_hodin_prace() {
return *pocet_prac; //crashes but dont know why?
}

I could not even compile it:

sss.cpp:1: error: expected constructor, destructor, or type conversion
before '=' token
sss.cpp:2: error: expected constructor, destructor, or type conversion
before '=' token
sss.cpp:3: error: expected constructor, destructor, or type conversion

sss.cpp:4: error: expected unqualified-id before 'for'
sss.cpp:4: error: expected constructor, destructor, or type conversion

Show us something that acutally compiles. We have no indication where the
code snippet above the function declaration takes place. In mane? In a
constructor? In an initializer? Never?

Since you're getting an error when dereferencing the pointer, I'm guessing
never.

Come on, quit horsing around.

Lol. Yeah, I'm bad at typos.
