IloExprArray is the array class of the expressions class.
For each basic type, Concert Technology defines a corresponding array
class. IloExprArray is the array class of the expressions
class (IloExpr) for a model.
Instances of IloExprArray are extensible. That is, you can
add more elements to such an array. References to an array change whenever
an element is added to or removed from the array.
Most member functions in this class contain assert
statements. For an explanation of the macro NDEBUG (a way to
turn on or turn off these assert statements), see the concept
Assert and NDEBUG.

| Constructor Detail |
|---|
This constructor creates an empty array of expressions for use in a
model. You cannot create instances of the undocumented class
IloDefaultArrayI. As an argument in this default constructor,
it allows you to pass 0 (zero) as a value to an optional argument in
functions and member functions that accept an array as an argument.
This constructor creates an array of n elements. Initially,
the n elements are empty handles.

This subscripting operator returns an expression argument for use in a
constraint or expression. For clarity, let's call A the
invoking array. When anIntegerExpr is bound to the value
i, the domain of the expression is the domain of
A[i]. More generally, the domain of the expression is the union
of the domains of the expressions A[i] where the i
are in the domain of anIntegerExpr.
This operator is also known as an element constraint.
