    • Constructors in Derived Classes

      A constructor plays a vital role in initializing an object. An important note, while using constructors during inheritance, is that, as long as a base class constructor does not take any arguments, the derived class need not have a constructor function.

      Integer Overflow

      An integer overflow, or integer wrapping, is a potential problem in a program based upon the fact that the value that can be held in a numeric datatype is limited by the data type’s size in bytes. ANSI C uses the following minimum sizes: data type size (bytes) char 1 short 2 int 2 long

    • How to Declare a Constant in Java

      How to Declare a Constant in Java

      Java does not directly support constants. However, a static final variable is effectively a constant. The static modifier causes the variable to be available without loading an instance of the class where it is defined. The final modifier causes the variable to be unchangeable. Ex: public static final int FOUNDING_YEAR = 2001; Naming Standards for

    • Circular Queue

      Circular Queue

      The difficulty of managing front and rear in an array-based non-circular queue can be overcome if we treat the queue position with index 0 as if it comes after the last position (in our case, index 9), i.e., we treat the queue as circular. Note that we use the same array declaration of the queue.
