C++ programming

STRUCTURE OF A C PROGRAMMING

-Creating -MECHANICS, Compiling and Running a C Program

C++ CHARACTERISTICS

-General-purpose language that is as efficient and portable as C -Compatible with C, therefore providing a smooth transition from C

Bjarne Stroustrup

-developed C++ at Bell Labs in 1983 -C++ is an extension of C.

int main ()

-initiates the declaration of a function -the function called when the program is run

<<

-insertion operator -indicates that what follows is inserted into std::cout.

Statement

-is an expression that can actually produce some effect. It is the meat of a program, specifying its actual behavior -are executed in the same order that they appear within a function's body.

C Programming Language

Programming Language for UNIX OS

/*...*/

block comment

Dennis Ritchie

created the C Programming Language in the early 1970's

block comment

discards everything between the /* characters and the first appearance of the */ characters, with the possibility of including multiple lines.

line comment

discards everything from where the pair of slash signs (//) are found up to the end of that same line.

Comments

do not affect the operation of the program; however, they provide an important tool to document directly within the source code what the program does and how it operates.

std::cout

identifies the standard character output device (usually, this is the computer screen)

{}

indicates the beginning of main's function definition and end

#include <iostream>

instructs the preprocessor to include a section of standard C++ code, known as header iostream, that allows to perform standard input and output operations

//

line comment

Using namespace std

make it easier to reference operations included in that namespace.

;

marks the end of a stetement

std::cout << "...";

statement output function
