silly array element counter..

[ct]

Ok.. first of all I am a bit new to STL, however I am having this problem in C++.

I have got a function defined as

int MyClass::MyString(string str[])
{
//code

}

Is there any way to find out how many elements of array are being passed to the function.
I have no way to know how many functions are being passed but only know that the constratints would be say 1 to 100 as I don't have the code that calls the function and am only supposed to write this single class.

doing (sizeof(str)/sizeof(str[0])) returns "1" and is of no use..

is there some way to find count the elements of this string array..
