[C++] Pointers and Vectors.

[Samael88]

Okay, so I am trying to use pointers and vectors together and I am a bit confused.

My question is, if I have the code provided below, how do I clean it up afterwards?

vector <int*> myVector;
int* a = new int;
*a = 8;
myVector.push_back(a);

delete myVector[0];

Edit:
It seams you can merge those two lines
int* a = new int;
*a = 8;

int* a = new int(8);

Does that delete the entire vector or just the first variable?
Edit:
If I have more than one variable in my vector should I loop through it then and delete them all separately?

Well "myVector[0]" is an array/vector look up/dereferencing so it can't be freeing the whole vector.

>If I have more than one variable in my vector should I loop through it then and delete them all separately?

Well I guess so but maybe there could be some better way(foreach) or something idk... =)

Edit:
Probably the vector has a destructor that will delete it when it gets out of scope.

Always a good reference:

As pointers are fugly.

Anywho, not sure if there is no definite way to clean up the code as you cannot delete integer a otherwise its value is inaccessible in myVector, and myVector is the vector to be used elsewhere in the code (I assume). Simply delete all pointers when you are done using them (delete a).
