The rules for constructing real constants are as mentioned below : 1. A real constant must have atleast one digit. 2. A real constant can only have one decimal point. 3. Positive and negative sign can be assigned to a constant and if there is no sign, by default it is being treated as positive...

The rules for constructing variable's names are as mentioned below : 1. Variable name can only have one to thirty one characters. 2. Variables name are case sensitive. 3. Only alphabets, digits, underscore characters can be used. 4. You can use any set of allowed characters with the first...

Web design is a rewarding career beyond doubt and you can do well by utilizing your creativity and using the right tool. Selecting the right design tool for website creation is very important. There is a plethora of web design tools a professional can pick from and each has its areas of...

It is no longer mandatory that you will have to use manual coding or a fully fledged web design tool to make compelling websites or apps. You can also make use of well developed frameworks for such needs and Bootstrap is one notable example of this. It is a mobile centric, responsive and...

Insertion of node means addition of new node to an existing linked list or creating a new linked list if node is does not exist. These are the different way Insertion can be performed. Insertion is possible at the beginning of the list. Insertion is possible in the middle of the list. Insertion...

A linked list is chain of objects in which each object consist of data and pointer that stores the address of the next logical object in the list. Linked list dynamically change their size that is the memory is allocated at run time depending on user’s requirement. These are the various types of...

C++ input and output system manages two integer values associated with a file. That is the get pointer and the put pointers The get pointer: the get pointer specifies the location in the file where the next read operation will occur. The put pointer: The put pointer specifies the location in the...

Binary input and output operation means that the -64357.789 is written in floating point numbers or float representation consuming four bytes of space. When text file are reading by using the operator “>>”, certain character translation appear. This is the example, white space characters are...

The istream class is used to receive data from the input device and the input stream operators are defined in the istream class. The operator “>>” called extractor, accepts any built in datatype passed as argument. The object cin is attached to the standard input device, which is keyboard. There...

Stream classes have their own member data, function and definitions. The ostream class contains functions defined for the output operations. These operations are called stream insertions. The header file iostream contains the definitions of operator “<<” that is called inserter and the object...

The file is the stream of characters or the flow of related data. There are two types of stream we use in the C++ that is Input stream: which allow to the user to read the characters. Output streams: which allow to the user for write the characters. Each stream is associated with a particular...

When we use the multiple inheritance, then the constructor invoke in some order which is describe below. Virtual base class constructor invoke in order of inheritance. Non-virtual base class constructor invoke in order of inheritance. Member objects constructor invoke in order of declaration...

The concept of virtual base class is to have only one copy of the base class member in memory. Inheriting a class more than once through multiple paths create multiple copies of base class members in the memory. Thus, by declaring the base class inheritance is virtual, only one copy of the base...

The selection of program to code an application depends on nature of application as is being used for what purpose. If in case there are number of languages known to code the same application, than the best known for all programmers and common should be preferred. There should be term familiar...

Documentation of programming an software is essential due to below mentioned factors : It solves the issue of indispensability of any individual for any organization. It helps in making software easier to modify and to maintain properly for future use. It also helps in restarting or functioning...

If compared to logical errors, syntax errors are much easier to locate and corrected due to fact that all programmers are designed in a fact that they automatically detect syntax errors. If a program instruction contains an error that belongs to a particular field, all other instructions that...

There are number of factora which are believed to be important for making good programming language. These are as mentioned below: 1. Simplicity Make program as simple as you can and easy to learn. 2.Abstraction They should have the ability to define and then using the complicated structures...

C++ supports the multiple inheritance. Multiple inheritance is the implementation of the Subclass inheriting the properties from the multiple base class. If we take the example of multiple inheritance in real life then the children is inheriting the properties of their parents. If the Derived...

These are the various common differences between static and the dynamic polymorphism. Static polymorphism is the more efficient whereas the Dynamic polymorphism is more flexible. Statically bound methods are methods that are bound to their calls at the compile time. Whereas Dynamic function...

A function with no body is called the pure virtual function. The virtual function of base class is not used. If we take the example of employee class the calc_net_salary () is never invoked. Because employee belongs to two category (confirmed /trainee), and the net salary is depends on it then...
