2. Serializability depends on the underlying collection type. For example, if a typed pointer array is based onCObArray, it is serializable; if based onCPtrArray, it is not serializable. In general, the “Ptr” classes cannot be serialized. 3. If marked Yes in this column, a nontemplate c...

A variable is an identifier that refers to the data item stored at a particular memory location. This data item can be accessed in the program simply by using the variable name. The value of a variable can be changed by assigning different values to it a
