I'm begginer c++ programmer . Array of pointers?!
I'm beginner C + + programmer. I have to implement a code that asks you to simulate the election of the president (in a simplified way). The text says to predict 3 classes: 1) Candidate 2) Elector 3) Seat. Seat In Electors can vote up to 10 the list of which is unknown. Each elector expresses the preference of a candidate by inserting a string and stores the data entered anonymously. I do not understand how I should handle this part. I created a class where Elector header declare the default constructor without parameters, I get the output through the overload of operator Flow "<<", full name of each elector, while using the set and get methods to store the id of each elector (I assumed that each voter will have a different id) and use set and get well to store the string that indicates the preference of a candidate. How do I store the value of each string you insert in the class Elector in order to increase the array of objects Candidate? . I think we need to create an array of pointers to an object Candidate .. ? But how do you .. Help!

You create an array of pointers the same way as you create an array of any other type.
For example, an array of 10 integers would be:
and an array of 10 pointers to integers would be:
Although I'd advise you to learn about STL vectors, instead of C-style arrays. They're much safer and easier to use, once you've learnt them.

int myIntArray[10];and an array of 10 pointers to integers would be:
int* myIntPtrArray[10];Although I'd advise you to learn about STL vectors, instead of C-style arrays. They're much safer and easier to use, once you've learnt them.
