Develop a substring operator using operator() in C++. The arguments should be the starting position for the substring and the length of the substring. The result should be a copy of the substring starting at the given position within our own data and ending at most the given length from the start. For example: Object's Value Operator Call Resulting Object's Value "bob wuz here" obj(0,4) "bob " "bob wuz here" obj(8,14) "here" (ran out of characters) "bob wuz here" obj(14,4) "" (nothing there) "bob wuz here" obj(4,1) "w" If the start position doesn't exist, send back an empty string (as we've defined). If there aren't 'length' characters left in our string after the given start position, return what we do have. Don't forget to write a test application to show that your operator works. (Perhaps you could modify the existing String test app?)
