I don't think you can. You will need to keep track of how many strings you stick into that array. Better yet, use vectors:

vector<string> MyStrings;
MyStrings.push_back("Hello");
MyStrings.push_back("Another string");

cout << "Number of strings saved: " << MyStrings.size();

If you wanted to do something similar with arrays you'd do this:

int size = 0;
string MyStrings[100];
MyStrings[size++] = "Hello";
MyStrings[size++] = "Another string";

cout << "Number of strings saved: " << size;

You could make a class if you like that is somewhere in between:

class STRINGS
{
    int _size;
    string _string[100]; // If you dynamically allocate this it's essentially the same as vector
public:
    STRINGS() { _size = 0; }
    void push_back(string in) { _string[_size++] = in; }
    int size() { return _size; }
};

This would let you:

STRINGS MyStrings();
MyStrings.push_back("Hello");
MyStrings.push_back("Another string");

cout << "Number of strings saved: " << MyStrings.size();
