#include <iostream>
#include <string>
#include "Trump.hpp"
#include <vector>

using namespace std;

int main(int argc, const char * argv[]) {
  
    vector<Trump*> vec;
    vec.push_back(new Trump(60));
    vec.push_back(new Trump(70));
    vec.push_back(new Trump(80));
    for(vector<Trump*>:: iterator it = vec.begin(); it != vec.end(); it++){
        cout<<(*it)->getAge()<<endl;
    }
    
}


If "it" is a pointer to first position of vec.. why *it->getAge(); doesn't work?.. im forced to (*it)->getAge();

Why?.. there's something in my reasoning that does not work..

That's because * has lower precedence than ->. *it->getAge() is handled like *(it->getAge())
