We can have a lesson on std::vector and std::array, but C-style arrays are no where near being outdated, less elegant, or less important. In terms of learning, you will want to start from the latter before you proceed to the former two. 12th Nov 2017, 4:24 PM Hatsy Rei + 13 ...
The introduction of array class from C++11 has offered a better alternative for C-style arrays. The advantages of array class over C-style array are :- Array classes knows its own size, whereas C-style arrays lack this property. So when passing to functions, we don’t need to pass size...

it is being more consistent to always use arrays as arrays - this will be reflected in the function formal parameter. The actual parameter can also be made explicit by passing the address of the first element of the array, rather than just its name: ...

std::arrayis a container that encapsulates fixed size arrays. This container is an aggregate type with the same semantics as a struct holding aC-style arrayT[N]as its only non-static data member. Unlike a C-style array, it doesn't decay toT*automatically. As an aggregate type, it can ...
Previous versions of the compiler did not support type deduction of arrays from an initializer list. The compiler now supports this form of type deduction and, as a result, calls to function templates using initializer lists might now be ambiguous or a different overload might be chosen than in...
