C++ class

 

C++ Class Definitions

A class has a class name, a set of attributes (data members and characteristics) and a set of actions or services. Class is an explicit datatype. The class specified the type and scope of variables and functions declared inside the class. The variables declared inside the class are known inside the class are known as data member or menber variables and the functions are called member functions. The body of the class is enclosed within braces and terminated by the semicolon. The keyboards private, public and protected are known as visibility levels, which defines the visibility of member.  A C++ class is like a blueprint for an object.

  • A Class is a user defined data-type which has data members and member functions.
  • Data members are the data variables and member functions are the functions used to manipulate these variables and together these data members and member functions defines the properties and behavior of the objects in a Class.
  • In the above example of class Car, the data member will be speed limit, mileage etc and member functions can be apply brakes, increase speed etc.

Introduction of C Language

Image
Hello Friends, Here we will know some basics of C Language. So let's Start...... C Programming C is a powerful general-purpose programming language. It is fast, portable and available in all platforms. If you are new to programming, C is a good choice to start your programming journey. C  is a procedural programming language. It was initially developed by Dennis Ritchie in the year 1972. It was mainly developed as a system programming language to write an operating system. The main features of C language include low-level access to memory, a simple set of keywords, and clean style, these features make C language suitable for system programmings like an operating system or compiler development. Many later languages have borrowed syntax/features directly or indirectly from C language. Like syntax of Java, PHP, JavaScript, and many other languages are mainly based on C language. C++ is nearly a superset of C language (There are few programs that may compil

Constant in C

Image
                    Constant in C Constant The constant in  C are available to the values which do not change during the execution of the program. There are several types of constant in C: a.Integer Constant 5,10,15......., these are the sequence of the number from 0(zero) to nine without decimal point or fractional part or any other symbols. b.Real Constant Real Constant are often known as floating point constant. Integer constant are unfit to represent floating value,then it is represented by real constant. c. Character Constant Character Constant has two types as follows: 1. Single Character Constant A character Constant is a single character. They are also represented with a single digit or a single special symbol or white space (blank space) enclosed within a pair of single quote(") marks. 2.String Constant String Constant of character in closed within a double quote mark("....").The string may be combination of all kinds of symbol. exa

Computer generation

Image
                Computer Generation 1st generation The period of 1st generation was 1942-1954. The main features are- *Vaccum tube technology *Unreliable *Supported Machine Language Only *Very Costly *Generate lot of heat *Need A.C *Non Portable *Consumed lot of Electricity 2nd Generation The period of second generation was 1952-1964. The main features are- *Use of transistor *Reliable as compared to first generation computer *Smaller size as compared to first generation *Consumed less electricity *Faster than first generation *Still very Costly *Support machine and assembly language *A.C needed   3rd generation The period of third generation was1964-1972. *The main features are- *Use of integrated circuit *More reliable *Smaller size *Generate less heat *Faster *Still costly *A.C needed *Consumed lesser electricity 4th generation The period of fourth generation was 1972-1990. The main features are- *Very Large Scale Inte
