How do I declare an array with a custom class?

I'm trying to declare an array with a custom class. When I added a constructor to the class, my compiler complains that there's "No matching constructor for initialization of name[3]".

Here's my program:

#include <iostream>

using namespace std;

class name {
  public:
    string first;
    string last;

  name(string a, string b){
    first = a;
    last = b;
  }
};

int main (int argc, const char * argv[])
{

  const int howManyNames = 3;

  name someName[howManyNames];

  return 0;
}

What can I do to make this run, and what am I doing wrong?
