returning reference to a vector from a method and using its public members
- by memC
dear experts,
I have a vector t_vec that stores references to instances of class Too. The code is shown below. In the main , I have a vector t_vec_2 which has the same memory address as B::t_vec.
But when I try to access t_vec_2[0].val1 it gives error val1 not declared.
Could you please point out what is wrong? Also, if you know of a better way to return a vector from a method, please let me know! Thanks in advance.
class Too {
public:
Too();
~Too(){};
int val1;
};
Too::Too(){
val1 = 10;
};
class B {
public:
vector<Too*> t_vec;
Too* t1;
vector<Too*>& get_tvec();
B(){t1 = new Too();};
~B(){delete t1;};
};
vector<Too*>& B::get_tvec(){
t_vec.push_back(t1);
return t_vec;
}
int main(){
B b;
b = B();
vector<Too*>& t_vec_2 = b.get_tvec();
// Getting error
std::cout << "\n val1 = " << t_vec_2[0].val1;
return 0;
}
