4> Multiple Inheritance : Java does provide multiple inheritance in form of Interfaces, In Java a class can not inherit from more than one class but it definitely can implement any number of interfaces 5> Templates: in c++ give such a lot of flexibility and avoids redundant coding which again...

One of the best things you can do to reduce the size of your program is to avoid using large standard library routines. Many of the largest are expensive only because they try to handle all possible cases. It might be possible to implement a subset of the functionality yourself with signifi...

The first-level macros,DECLARE_DYNAMICandIMPLEMENT_DYNAMIC, permit run-time access to the class name and its position in the hierarchy. This, in turn, allows meaningful diagnostic dumping. The second-level macros,DECLARE_SERIALandIMPLEMENT_SERIAL, include all the functionality of the first-level ma...
This fails to work on some systems where the assembler is unable to read from a pipe; but the GNU assembler has no trouble. -specs=file Process file after the compiler reads in the standard specs file, in order to override the defaults which the gcc driver program uses when determining ...
They implement the behavior that is unique to each of their respective types. A second aspect of inheritance, spoken of as polymorphism , is the ability of a parent type to refer to any of the subtypes that are inherited from it. An Employee, for example, can address its own type or ...
But I often prefer to just add//comments after the macro body describing the tricky bits. I think this makes the macro body easier to read, but still provides the (much-needed) documentation. Program in American English Developing in the same language, using the same spelling and vocabulary,...
