What is Language?

Language is a system that consists of the development, acquisition, maintenance and use of complex systems of communication, Particularly the human ability to do so; a language is any specific example of such a system. The scientific study of language is called linguistics.

 What is Programming language?
A programming language is a vocabulary and set of grammatical rules for instructing a computer or computing device to perform specific tasks. The term programming language usually refers to high-level languages, such as BASIC, C, C++, COBOL, Java, FORTRAN, Ada, and Pascal.

Development of Programming language:

The First language that was developed is ALGOL-60 in the year 1960. In place of ALGOL-60, CPL language was introduced in the year 1963 in Cambridge university. In place of CPL, BCPL language introduced by Martin Richard in Cambridge University in the year 1967. Then B language was created by Ken Thompson at  "AT & T" bells' Laboratory in 1970. It was more powerful than BCPL and harder also. In the year 1972 Dennis Ritche at "AT & T" bells' Lab develop the C language. The C language is the combination of BCPL and B language and own concepts of the developer.

The C++ Programming language was developed at  "AT & T" bells' Laboratory in 1980 by Bjarne Stroustrup. He found C language lacking for simulation and decided to extend the language by adding feature from his favorite language Simula-67.

Application of C++

C++ programs are easily maintained and it can be expand very easily when a new feature needs to be implemented., It is very easy to add the existing structure of an object. Since C++ allows us to create related object, We can build special object oriented library which can be used later by many programmers. It is a versatile language for handling very large program. And it is suitable for virtually any programming task including development of editors, compilers, database, communication system and any complex real life application system. It is expected that C++ will replace C language as a general purpose language in the near future.

A simple C++ Program to show the summation of two number:

#include<iostream.h>                                                                            //header file
#include<conio.h>
int main()                                                                                              //Main function
{
clrscr();                                                                                                //clear screen
int a,b,c;
cout<<"Enter First number:\t";
cin>>a;
cout<<"Enter second number:\t";
cin>>b;
c=a+b;                                                                                             //Logical part
cout<<"The Summation result of two number that you have entered is:\t"<<c;
getch();                                                                                             //To pause the screen
return 0;                                                                                           //returning value
}   

Output of the program will be 

Enter First number:     5
Enter second number:     7
The Summation result of two number that you have entered is:     12
