What is C++?

It is an object-oriented programming (OOP) language that is viewed by many as the best language for creating large-scale applications. C++ is a superset of the C language.


What is C++?

A high-level programming language developed by Bjarne Stroustrup at Bell Labs. C++ adds object-oriented features to its predecessor, C.


History of C++


History of C++


C++ was written by Bjarne Stroustrup at Bell Labs during 1983-1985. C++ is an extension of C. Prior to 1983, Bjarne Stroustrup added features to C and formed what he called "C with Classes". He had combined the Simula's use of classes and object-oriented features with the power and efficiency of C. The term C++ was first used in 1983.

History of C++


C++ was designed for the UNIX (operating system that originated at Bell Labs in 1969)system environment.

History of C++


Prior to C++, C was a programming language developed at Bell Labs circa 1969-1973. The UNIX operating system was also being developed at Bell Labs at the same time. C was originally developed for and implemented on the UNIX operating system.

History of C++


Dennis Ritchie restructured the language and rewrote the compiler and gave his new language the name "C" in 1972.

History of C++


C++ programming language was initially created by Bjarne Stroustrup, as a "better C". C++ was an attempt to extend and (to some extent) change the C programming language to overcome some of the common and big problems with the language. C++ was first standardized in 1998, and as such, is a much younger language than C.

Structure of a Program in C++




The programmer can use them to include short explanations or observations within the source code itself. In this case, the line is a brief description of what our program is.

//



Lines beginning with a hash sign (#) are directives for the pre-processor. They are not regular code lines with expressions but indications for the compiler's pre-processor. This specific file (iostream) includes the declarations of the basic standard input-output C++,

#include <iostream>



Corresponds to the beginning of the definition of the main function. The main function is the point by where all C++ programs start their execution, independently of its location within the source code.

int main ()



() is a function declaration: In C++, what differentiates a function declaration from other types of expressions are these parentheses that follow its name. Optionally, these parentheses may enclose a list of parameters within them.

int main ()



Is the name of the standard output stream in C++, and the meaning of the entire statement is to insert a sequence of characters into the standard output stream

cout <<



This character is used to mark the end of the statement and in fact it must be included at the end of all expression statements in all C++ programs

;



The return statement causes the main function to finish. This is the most usual way to end a C++ console program.

return 0;

Example Program in C++


Welcome to the wonderful world of C++!!!

#include <iostream>

int main(){

cout << "Welcome to the wonderful world of C++!!!";

return 0;}
