is there a method in c++ to find the length of string*?
A string* is a pointer to an object of type string.
A pointer is typically the size of an int or two, but it's dependent on your system. You can find the size of any object with sizeof.
int size = sizeof(someStringPointer);
I suspect you actually want to know the length of a string object, rather than the size of a pointer. If the string object is a std::string, it comes with the member function length() and also size().
string someString("A nice string to use as an exmaple");
int size = someString.size();
If you meant a C-style array of characters, you can use the strlen function, as follows.
/* strlen example */
int main ()
printf ("Enter a sentence: ");
printf ("The sentence entered is %u characters long.\n",strlen(szInput));

Your question is kind of vague, but possible any one of these :
string->size(); //if you are using std::string *
strlen(string); //if you are using c-style string
