we understand nothing by custom types in c++

Answer 2

Custom types in C++ can also be called as user-defined data types. The term is generally used to refer to objects, unions and structures.

Structures are the user-defined data members in a program which are declared and defined by the user and can have multiple data elements inside them which can be of same or different primitive data types.

However, the data members of a structure can also be a data element of another structure type/user-defined data type.
