Is Class a Variable?

[Penna Elabi]

Is class a variable? Can a variable consist of variables?

For example, a vector is a class, so is this vector a variable when it
includes two int variables:

vector < int > exampleVector( 2, 2 );

Is class a variable? Can a variable consist of variables?

For example, a vector is a class, so is this vector a variable when it
includes two int variables:

vector < int > exampleVector( 2, 2 );

"vector<int>" is not a variable, any more than "int" is; it is the name of
a specific *type* of variable. "exampleVector" is a variable which
contains two variables that don't have names of their own.

Some programmers say "class" when they really mean "object (or variable)
of that class (type)", which can be confusing.
