Aggregation and composition are two sides of the same coin. Both an aggregate and a composite object encapsulate one or more sub-objects. But while a composite object owns its sub-objects, an aggregate object does not. That is, when a composite object is destroyed, its sub-objects are also destroyed. But with an aggregate object, the sub-objects are not destroyed.
Aggregate objects typically use references or pointers to refer to their sub-objects, whereas composite objects typically use member variables or pointers to refer to their objects. In essence, a composite object instantiates its own sub-objects, whereas an aggregate object's sub-objects must be passed to it, typically via the constructor.
In complex models you will often find a combination of composition, aggregation and inheritance, even within the same object.
C: there are no methods in C. C++: no.
c is procedure oriented and c++ is object oriented & much newer.
If a + b + c + d + 80 + 90 = 100, then a + b + c + d = -70.
C++ is related to C, the language from which it is derived.
println is not a C++ keyword.

b+b+b+c+c+c+c =3b+4c
c + c + 2c + c + c = 6c
b + b + b + c + c + c + c = 3b + 4c
4c
c + c + c + c + c = 5 * c.
There are no "primary and secondary keys" in c and c plus plus.
3c
There is no such thing as 'unix C++'.
They do exist in C and C++.
