vector class.

It means that the Variable object is outside the vector object and you must create the objects using "new" operator.

$6.$ Simple error check for variable names: cannot start with a digit.

$7.$ There must be at least $5$ functions including main$()$

$8.$ Please do not use arrays. You must use the $C++$ vector class to manage the list of object pointers.

$9.$ The vector must be a private data member in the "VariableListManager" class. No vector class and object can be referenced or used outside the VariableListManager class.

$10.$ Please minimize redundant code. Please write functions if you need to perform the same tasks multiple times.

$11.$ There should be at most one return statement in each function.

$12.$ Please do not iterate through the list in the vector more than once for each task and please do not iterate to the end of the list unnecessarily.

and not to keep track of its actual number of variables separately because the vector object has its size.

$14.$ You can assume that the user enters the variable assignment correctly $($e$.$g$.$ correct $\text{'}=\text{'}$ operator and integer value separated by blanks$)$

$15.$ All data members must be declared private in the class.

$16.$ The "Variable" class must not provide the default constructor.
