C++ is used to create computer programs.

Difference Between C and C++.

C is middle-level programming language which was developed at Bell Lab in 1972 by Dennis Ritchie. C language combines the features of Low level as well as High-level Language. Hence its considered a middle-level Language.C is a high-level classical type programming language that allows you to develop firmware and portable applications. The C language was developed with an objective of writing system software. It is an ideal language for developing firmware systems.

C++ is a computer programming language that contains the feature of C programming language as well as Simula67( a first object Oriented language). C++ introduced the concept of Class and Objects.It encapsulates high and low-level language features. So, it is seen as an intermediate level language. Earlier it was called "C with classes" as it had all the properties of the C language.


C Programming language

C was initially used for system development work, particularly the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language. Some examples of the use of C might be.

  • Operating Systems
  • Language Compilers
  • Network Drivers
  • Databases
  • Assemblers
  • Text Editors
  • Print Spoolers
  • Language Interpreters

A C program can vary from 3 lines to millions of lines and it should be written into one or more text files with extension ".c".

professional language for various reasons
  1. Easy to learn
  2. Structured language
  3. It produces efficient programs
  4. It can handle low-level activities

C++ Programming language

C++ is a cross-platform language that can be used to create high-performance applications.C++ was developed by Bjarne Stroustrup, as an extension to the C language.C++ gives programmers a high level of control over system resources and memory. The language was updated 3 major times in 2011, 2014, and 2017 to C++11, C++14, and C++17.

Use C++

C++ is one of the world's most popular programming languages.C++ can be found in today's operating systems, Graphical User Interfaces, and embedded systems.C++ is an object-oriented programming language which gives a clear structure to programs and allows code to be reused, lowering development costs.

C++ classes

C++ is an object-oriented programming language. Everything in C++ is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. Attributes and methods are basically variables and functions that belongs to the class. These are often referred to as "class members". A class is a user-defined data type that we can use in our program, and it works as an object constructor, or a "blueprint" for creating objects.

C++ Functions

A function is a block of code which only runs when it is called. You can pass data, known as parameters, into a function. Functions are used to perform certain actions, and they are important for reusing code: Define the code once, and use it many times.

C++ Syntax

#include
#include is a header file library that lets us work with input and output objects, such as cout . Header files add functionality to C++ programs.

The best way is to develop and follow a plan. Start with your goals in mind and then work backward to develop the plan. What steps are required to get you to the goals? Make the plan as detailed as possible. Try to visualize and then plan for, every possible setback.
