I was wondering if

*pntr.age = 19;

is valid considering that pntr is a pointer to an object that has age as a varible. If it is valid, can it be used with an array of pointers to objects? if yes can i get an example please? thank you.

No its not valid. And thats because of the operator precedence.

Here is an example that shows how to make it valid :

class Int{
public :
 int var;
 Int() { var = 0; }
 Int(const int& i) { var = i; }
};

int main(){
 Int * num  = new Int(0);
 //how to access num data
 (*num).var = 1; //option 1
  num->var = 1; //option 2
 delete  num;
}

The operator -> is a special operator and is made for the sole reason
to make the syntax better. Rather than doing (*num).var = 0, doing
num->var = 0 is the same thing.
