deleting an array that stores pointers to some objects
- by memC
hi,
I am storing pointers to elements of a vec_A in an array A* a_ptrs[3] . Assume that vec_A will not be resized. So, a_ptrs[i] will point to the correct element.
My question is:
Suppose A* a_ptrs[3] is declared in a class B. Since it is not created using 'new' I am guessing I don't need to delete it in the destructor. Am I right??
class A {
public:
int getNumber();
A(int val);
~A(){};
private:
int num;
};
A::A(int val){
num = val;
};
int A::getNumber(){
return num;
};
int main(){
int i =0;
int num;
std::vector<A> vec_A;
for ( i = 0; i < 10; i++){
vec_A.push_back(A(i));
}
A* a_ptrs[3];
a_ptrs[0] = &vec_A[0];
a_ptrs[1] = &vec_A[3];
a_ptrs[2] = &vec_A[5];
for (i = 0; i<3; i++){
std::cout<<"\n: a_ptrs[i].getNumber() = "<<a_ptrs[i]->getNumber();
}
std::cout << "\nPress RETURN to continue...";
std::cin.get();
return 0;
}
