Acces an element in a vector of pointers

Question

This is probably very simple but I can't find it:

I want to acces an element in a vector of pointers

 class Tile { public: Tile(int xPosition, int yPosition, float tileWeight); float getValue() const {return value;}; void setValue(float newValue) {value = newValue;}; int getXPos() const {return xPos;}; int getYPos() const {return yPos;}; void setXPos(int newPos) {xPos = newPos;}; void setYPos(int newPos) {yPos = newPos;} private: int xPos; int yPos; float value; }; class Enemy : public Tile { public: Enemy(int xPosition, int yPosition, float strength); };

In another class

std::vector<Enemy*> enemies; enemies = myWorld->getEnemies(5);

How can I acces the value of just the first member in another class I can't seem to acces it in another class

MySquare::movePlayer(std::vector <int> directions, std::vector<Enemy*> enemies,std::vector<int*> healthPks){ }

For example to call getValue function on the first item in the vector, use

enemies[0]->getValue();
