Advantages and Disadvantages of C++

C++ is based on the C language, and it was developed in the early 1980s by Bjarne Stroustrup at AT&T Bell Laboratories, Here "++" use for the extension because "++" is a syntactic construct used in C to increment a variable. Most of the C++ content is the super-set of "C", Due to this extension most C programs can be compiled using a C++ compiler.

A C++ program is a collection of commands, which tell the computer to do "something." This collection of commands is usually called C++ source code C++ is the Mid-Level programming language because it acquires the feature of Low level as well as a high-level programming language. Using C++ Programming Language we can create a different kind of Software, These are:

  • System software
  • application software
  • device drivers
  • embedded software
  • high-performance server and client applications and
  • entertainment software such as video games

What is C++

C++ is an object-oriented programming language

What is language?

  • A language is a software computer is an electronic device that cannot perform operating by own.
  • Language provides a set of instructions to perform operations by computer.
  • Language is nothing but a programming tool
  • C++ is the name of the language
  • ‘c’ language is derived from ‘B’ language
  • 'B’ language is derived from BCPL
  • ‘C’ language develops in the year 1972
  • C++ language is developed in the year 1980

What is a Program?

  • Set of instructions or collection of instructions and data.
  • Programming elements are
  • Data
  • instruction
  • To write a program to required Data and instructions.
  • programming is nothing but a process of organizing data and instructions according to given problem
  • object-oriented means rules and regularity 

What are Programming Principles

Programming principle defines a set of rules and regulations for the organization of data and instructions

  • Process Monolithic programming
  • Process-oriented programming
  • Modular oriented programming
  • Structure oriented programming
  • Object-oriented programming

Applications of C++

Using C++, you can develop system software like OS, Device Drivers, Network(N/W) protocols, PC – utilities

Application software you can develop application like

  • Database
  • Word processing
  • Spreadsheets
  • C++ is a general-purpose programming language better than ‘c’.
  • General-purpose means it is suitable for developing any software.
  • CUI means a character user interface

Programming Concepts

Unstructured programming / Monolithic programming

  • Organizing the data and instructions are organized in a sequential manner called Monolithic programming
  • In this approach instruction organization in sequential order
  • A sequence is a set of instructions used to solve a given problem. (Assembly level language, Basic)
  • Program execution is controlled by using a goto statement

Disadvantages

  • Code redundancy: the same operation has to be more than one time, the same sequence has to copy at some places.
  • The size of the program is incremental
  • The efficiency of the program is decreased

Procedural Programming

  • COBOL and Pascal are called procedural oriented programming languages.
  • In this approach instruction organized according to their operations by dividing into small programs or small pieces called the subroutine.
  • A subroutine is a small program within a program
  • This subroutine can be procedure or function

Advantages

Modularity: Dividing a program into small pieces 0 also called divide and conqueror According to their operations into small modular.

Re-usability: write code once and use it more than one time.

Readability:  Easy to read or understand.

Disadvantages

Data is global or local

Its emphasis on instructions, but not on data.

What is a Modular programming

In modular programming, a module is programming in this approach; the application contains one or more than one module

Each program is divided into a subroutine.

A program that contains a main is called an executable module which is compiled as .ex

A program which has doesn’t have a main is called a reusable module which is compiled as.LIB(Library)

Structured programming

‘C’ and pascal are called a structured programming language

Characters of structured programming

  • Modular programming
  • User-defined data types (Pascal)
  • scoped variables (local & Global)
  • One subroutine communicates with another by passing values
  • Top-down approach

Disadvantages

  • Data is global and global data does not have security
  • Unrelated operation access global data, if leads and logical errors.
  • Debugging application is complex
  • In a large program identifying which operation operates what data becomes complex.

Advantages of C++

  • Object-oriented
  • Portable language (writing a program irrespective of the operating system as well as Hardware)
  • Low-level language like Assembly language on Machine language called portable.
  • C++ use multi-paradigm programming. The Paradigm means the style of programming .paradigm concerned about logics, structure, and procedure of the program. C++ is multi-paradigm means it follows three paradigm Generic, Imperative, Object Oriented.
  • It is useful for the low-level programming language and very efficient for general purpose.
  • C++ provide performance and memory efficiency.
  • It provides a high-level abstraction.
  • In the language of the problem domain.
  • C++ is compatible with  C.
  • C++ used reusability of code.
  • C++ used inheritance, polymorphism.

Portability

  • Portability allows developing program irrespective of hardware
  • It allows moving the program development for one platform to another platform
  • C compatible (COMP): Programs developed in ‘C’ language can be moved without any modifications into C++
  • C++ is an object-oriented embedded language which is having the characteristics of low-level language & which is also developing the embedded software.
  • Which language having low-level features

Disadvantages

  • It has no security
  • Complex in a very large high-level program.
  • Used for platform-specific application commonly.
  • For a particular operating system or platform, the library set has usually chosen that locks.
  • When C++ used for web applications complex and difficult to debug.
  • C++ can't support garbage collection.
  • C++ is not secure because it has a pointer, friend function, and global variable.
  • No support for threads built-in.

What are the C and C++

C is a procedural (aka structural) programming language. In addition to beginning procedural, C++ is also an object-oriented programming language.
In C language, the solution is achieved through a sequence of procedures or steps. Therefore, C is a function-driven language.

How different is C# from C++?

C++ was designed to allow developers to use all of the existing features of C but provides some extensions to support object-oriented programming techniques in an intermediate-level programming language. C# is a complete outlive in this list. Despite its name, it has far more in common with Java than C or C++.

What is the difference between C & C++?

C C++
It is a structured programming language. It is an object-oriented programming language
It does not have an inline function It supports the inline function
It does not support functions with default arguments It supports() with default arguments
It does not have exception handling It supports exception handling
It having pointers It having a pointer and references
It  is a middle-level language It is a high-level language
It uses scanf() and printf() function for standard input and output It uses cin>>and cout<< for standard input and output
The C program file is saved with . C extensions C++ program file is saved with.CPP extension.
