15# main.cpp:
16#
17# include <string>
18#
19# void PrintSize ( const std::string& String );
20# void PrintNewString ( const std::string& String );
21# void PrintNewString2 ( const char* String );
22#
23# int main ( void ) {
24#
25#   PrintSize("hello");
26#   PrintNewString("hello");
27#   PrintNewString2("hello");
28#   printf("\n");
29#
30#   return 0;
31# }

33# foo1.cpp:

36#
37# void PrintSize ( const std::string& String ) {
38#   printf("\n String size %lu", String.size() );
