关于指针和向量的问题 [英] Question about pointers and vectors

问题描述

vector< Sprite *>框;

++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++ tank，rcBounds，BA_BOUNCE）;

休息;


box.push_back（ms）;


++ +++++++++++++++++++++++++++++++++++++++++++++++ （vector< Sprite *> :: iterator itr = box.begin（）;

itr！= box.end（）; itr ++）{

itr->更新（）;

}


这不行，我怎么能做得更好？

vector<Sprite*>box;
++++++++++++++++++++++++++++++++++
tank = new Bitmap(hdc, IDB_IMAGE2, g_hin);
Sprite * ms = new Sprite(tank, rcBounds, BA_BOUNCE);
break;

box.push_back(ms);

+++++++++++++++++++++++++++++++++++++++

for(vector<Sprite*>::iterator itr = box.begin();
itr != box.end(); itr++){
itr->Update();
}

This isn''t working how can I do it better?
