how to typedef array of 4 char to be used in map template
-
Alternatively you could use a union?
const struct ESDID
{
union
{
char c[4];
uint32_t i;
} x;
bool operator< (const ESDID e) const { return x.i < e.x.i; }
}; -
thanks richard I dont see in the map documentation when using the insert method with key of type struct '<' operator must be overloaded by the user
Actually there is (see std::map - cppreference.com[^]):
template<
class Key,
class T,
class Compare = std::less,
class Allocator = std::allocator>class map;
As it should be, because the
std::mapis a sorted container."In testa che avete, Signor di Ceprano?" -- Rigoletto

I understand the compare wont work correctly however what I dont see where the cast operator () is being used> Is dynamic cast used with pair i.e <> the same as the () operator ()

That’s not the way the map template is defined by Microsoft map Class | Microsoft Learn[^]
template<
class Key,
class T,
class Compare = std::less,
class Allocator = std::allocator>class map;
Microsoft:
template ,
class Allocator=allocator>>
class map;Do you see significant differences?

I see the third parameter to the template in microsoft docs is class traits in the cpp reference its class compare thank you

That's, you know, just a matter of naming... BTW, you are welcome.

this is just a general comment I thought MainFrame Assembler was Hard but being a C\C++ proficient coder is a very difficult skill to master as an aside just looked at the retrieval for the map class "AT" method it looks like if not found it generates an exception would of been a lot simpler if they gave back a bad return code Thank

You might use
find, to the purpose (see std::map<Key,T,Compare,Allocator>::find - cppreference.com[^])."In testa che avete, Signor di Ceprano?" -- Rigoletto
Thank you again you know I’m an assembler mail framer by birth when I post any question on IBMMAIN no matter how much research I have done I get screamed at wish IBMMAIN could be more like the codeproject thank. Time for to implement my code or actually yours
