Hi allo,

I am stuck on understanding the difference between what is the

std::initializer_list<std::pair<std::string,int>> 

and

std::map<std::string,int>

May you have an explanation?

n squared vs nLog(n)

edit:
do you know what an initializer list is? Like on a constructor implementation

Foo::Foo( ) : m_lNumber( 0 ), m_strName( NULL ), m_nID(0 )
{

}

ever seen anything like that?

I DID NOT get it

From Wikipedia:

The class std::initializer_list<> is a first-class C++11 standard library type. However, they can only be initially constructed statically by the C++11 compiler through the use of the {} syntax. The list can be copied once constructed, though this is only a copy-by-reference. An initializer list is constant; its members cannot be changed once the initializer list is created, nor can the data in those members be changed.
