now i got a new problem.
template <typename OutputIterator>
OutputIterator str_to_numlist(OutputIterator OutIt, const std::string&
s, typename OutputIterator::const_reference bound)
{
// some code.
}
template <typename ContainerType>
ContainerType encryptcpw::rsa_encrypt_list(const std::string& text,
typename ContainerType::const_reference e, typename
ContainerType::const_reference n)
{
typedef typename ContainerType::value_type T;
BOOST_STATIC_ASSERT(((std::numeric_limits<T>::is_i nteger) ||
(std::numeric_limits<T>::is_float)));
ContainerType encrypted_list;
encryptcpw::str_to_numlist(std::back_inserter(encr ypted_list),
text, n);
BOOST_FOREACH(T& val, encrypted_list)
{
val = encryptcpw::rsa_encrypt(val, e, n);
}
return encrypted_list;
}
my error is this
: error :
../cs512/c++/RsaEncrypt.cpp:64: instantiated from here
../cs512/c++/cppdef/rsa.cpp:205: error: no matching function for call
to 'str_to_
numlist(std::back_insert_iterator<std::list<BigInt eger,
std::allocator<BigIntege
r> > >, const std::basic_string<char, std::char_traits<char>,
std::allocator<cha
r> >&, const BigInteger&)'
Is it because the template parameter are different type that it gets
confuse? isn't const T& of std::back_inserter(std::list) same as const
T& of std::list
