string operator[] giving error

[FoodDude]

In MSVC++ 6.0,
I have lines similar to :

std::string reallylongstr;
reallylongstr = passed_parm;

//set counters

	while (!isalpha(reallylongstr[counter]) && (counter <= maxlen))
				{
				tempword = tempword + (*p).substr(counter, 1);
				counter++;
				std::cout<<tempword;
				}

I get "Error: overloaded operator not found" related to "reallylongstr[counter]." I try reallylongstr[2] in my watch window and get the same error.

Ideas?

What type is counter?

Does this work?

#include <string>
#include <iostream>

int main()
{
    std::string mystr("Hello World");
    std::string::size_type indx = 2;

    std::cout << mystr[indx] << std::endl;

    return 0;
}

Should output 'l'.

i think i have counter defined as either long or int. I'll try size_type and see if that makes a difference for my compiler.

Is that a compile error or just a watch window error?

The watch window doesn't evaluate overloaded operators very well. Try expanding the string and its data members a few times to see the internal data which should have the actual string value.
