char* str1 = "this is a test";
char str2[80];
copystr(str2, str1);
cout << str2 << endl;
return 0;
}

while( *src )
*dest++ = *src++;
*dest = "\0";
}

const string hello("Hello, how are you?");
string s(hello.begin(),hello.end());
// iterate through all of the characters
string::iterator pos;
for (pos = s.begin(); pos != s.end(); ++pos) {
cout << *pos;
}
cout << endl;
