  3. string function
#include <iostream>
using std::cout;
using std::endl;

#include <cstring>
using std::strlen;                        

int main()
{
   char *string1 = "asdfasdfasdfasdf";
   char *string2 = "     f    ";
   char *string3 = "       ";

   cout << "The length of \"" << string1 << "\" is " << strlen( string1 )
      << "\nThe length of \"" << string2 << "\" is " << strlen( string2 )
      << "\nThe length of \"" << string3 << "\" is " << strlen( string3 ) 
      << endl;
   return 0;
}

The length of "asdfasdfasdfasdf" is 16
The length of "     f    " is 10
The length of "       " is 7
