Map, IsAny methode exist

Hello,

Thanks, but it is not working.

I got this. left of '.identifier' must have class/struct/union

https://learn.microsoft.com/en-us/cpp/error-messages/compiler-errors-1/compiler-error-c2228?view=msvc-160

What is exactly auto?

class CPanelInfos
{

public:
	CPanelInfos() {};
	~CPanelInfos() {};
	
	map<CString, CPCBInfos> DicIndexInfos;

	bool IsGood();


	bool AllGood() const
	{
		//return std::all_of(DicIndexInfos.cbegin(), DicIndexInfos.cend(), [](map<CString, CPCBInfos> p1) { return p1.second.IsEqual; });

		return std::all_of(DicIndexInfos.cbegin(), DicIndexInfos.cend(), [](auto p) { return p.second.IsEqual; });
	}
};

I try this, the same

// ** Test
std::map<std::string, bool> mapT;
mapT["foo"] = false;
mapT["bar"] = true;
mapT["baz"] = false;

 bool any = std::any_of(mapT.begin(), mapT.end(), [](const auto& pair)
	{
		return !pair.second;
	});

 bool all = std::all_of(mapT.begin(), mapT.end(), [](const auto& pair)
	{
		return !pair.second;
	});

 bool none_of = std::none_of(mapT.begin(), mapT.end(), [](const auto& pair)
	{
		return !pair.second;
	});

What is different between any_of and all_of ?

Regards

Probably you are not using the modern Visual Studio. Try to specify the type:

bool AllGood( ) const
{
    return std::all_of( DicIndexInfos.cbegin( ), DicIndexInfos.cend( ), 
        []( map<CString, CPCBInfos >::value_type p ) { return p.second.IsEqual; } );
}

The all_of returns true is all of the values are true, or the collection is empty. The any_of returns true is there is at least one true value.
