// Purpose - to illustrate a potential error with the use of string variables.

#include <iostream.h>
#include "M:\C++ Programming\AP classes\apstring.h"

int main()
{
	apstring firstName = "Jane";		// user's first name

	cout << "The fourth letter of your name is: " << firstName[3] << endl;

	firstName[5] = 't';

	cout << "Your name is " << firstName << endl;
	// The assignment of the character 't' to the 6th position of firstName
	// 	 could cause a Windows error message like the window below.

	return 0;
}// end of main

The program causes a "friendly", index-out-of-range runtime error that is produced by the apstring class. However, if built-in C++ character arrays were used the error would result in a scary runtime error message like the one below.
