What is C++ Language?

First of all…

What is the definition of C++?

There currently is a massive migration occurring from C-based systems to C++ based system. There is a huge amount of so-called “legacy C code” in place.C has been in wide use for about a quarter of a century. Once people learn C++, they find it more powerful than C and often choose to move to C++. They begin converting their legacy systems to C++. They begin using the various C++ features generally called “C++ enhancement to C” to improve their style of writing C-like programs. Finally, they begin employing the object-oriented programming capabilities of C++ to realize the full benefits of the language. C++ is a general-purpose programming language with a bias towards systems programming that

  • Is a better C
  • Supports data abstraction
  • Supports object-oriented programming
  • Supports generic programming
  • It makes abstraction techniques affordable and manageable for mainstream projects

Who can Understand C++ Programming(Structured Programming)

It is appropriate for technically oriented people with little or no programming experience
It is appropriate for experienced programmers who want a deeper treatment of the language

The C++ standard library

Naturally, a C++ library facility that depends on classes and templates is not available in C.This includes

  • vectors
  • map
  • set
  • string
  • The STL algorithm i.e sort(),find()
  • iostreams
  • regex

For these, there are often C libraries based on arrays, pointers, and functions to help compensate. The main parts of the C standard library are

  • <stdlib.h> : which includes malloc() and free()
  • <stdio.h> : standard I/O
  • <string.h> : C-style string(manipulation and memory manipulation)
  • <math.h> : standard floating-point mathematical functions
  • <errno.h> : error codes for <math.h>
  • <limits.h> : sizes of integer types
  • <time.h> : for date and time
  • <assert.h> : debug assertions
  • <ctype.h> : character classification
  • <stdbool.h> : Boolean macros
