Example of String Concatenation

   // The append function can be used to extend a C++ string ...

   strB.append(strA);
   // The next statement is not allowed in Visual C++ 6.0
   strC.append(strA,3);
   // but this is a work around ...
   strC.append(strA,3,string::npos);
   strD.append(strA,3,4);
   char cstring[] = "An array of char";
   strE.append(cstring,8);               // value is "An array"
   strF.append("This is a string");

   // string& append( size_type n, char c );
   strG.append(10,'*');                  // value is "**********"

   // The += operator can be used with C++ strings, 
   // C strings and characters ...
   strH += strA;
   strI += cstring;
   strJ += "Hello";
   strK += 'X';

   // The + operator can be used with any combination of
   // C++ strings, C strings and characters ...
   strL = strA + strB;
   strM = "Boo" + strB;
   strN = strB + "Boo";
   strO = '*' + strB;
   strP = strB + '*';
