History of C++
During the 60s, while computers were still in an early stage of development, many new programming languages appeared. Among them, ALGOL 60, was developed as an alternative to FORTRAN but taking from it some concepts of structured programming which would later inspire most procedural languages, such as CPL and its succesors (like C++). ALGOL 68 also directly influenced the development of data types in C. Nevertheless ALGOL was an non-specific language and its abstraction made it impractical to solve most commercial tasks.
In 1963 the CPL (Combined Programming language) appeared with the idea of being more specific for concrete programming tasks of that time than ALGOL or FORTRAN. Nevertheless this same specificity made it a big language and, therefore, difficult to learn and implement.
In 1967, Martin Richards developed the BCPL (Basic Combined Programming Language), that signified a simplification of CPL but kept most important features the language offered. Although it too was an abstract and somewhat large language.

C++ Language FAQ
Frequently Asked Questions
What is C++?
C++ is a programming language. It literally means "increased C", reflecting its nature as an evolution of the C language.
Is it necessary to already know another programming language before learning C++?
Not necessarily. C++ is a simple and clear language in its expressions. It is true that a piece of code written with C++ may be seen by a stranger of programming a bit more cryptic than some other languages due to the intensive use of special characters ({}[]*&!...), but once one knows the meaning of such characters it can be even more schematic and clear than other languages that rely more on English words.Also, the simplification of the input/output interface of C++ in comparison to C and the incorporation of the standard template library in the language, makes the communication and manipulation of data in a program written in C++ as simple as in other languages, without losing the power it offers.[dl]

A brief description
ProgramsNowadays computers are able to perform many different tasks, from simple mathematical operations to sophisticated animated simulations. But the computer does not create these these tasks by itself, these are performed following a series of predefined instructions that conform what we call a program.
A computer does not have enough creativity to make tasks which it has not been programmed for, so it can only follow the instructions of programs which it has been programmed to run. Those in charge of generating programs so that the computers may perform new tasks are known as programmers or coders, who for that purpose use a programming language.

C++ Library Reference
The standard C++ library is a collection of functions, constants, classes, objects and templates that extends the C++ language providing basic functionality to perform several tasks, like classes to interact with the operating system, data containers, manipulators to operate with them and algorithms commonly needed.
The declarations of the different elements provided by the library are split in several files that shall be included in the code in order to have access to its components:
Input/Output Stream LibraryProvides functionality to use an abstraction called streams specially designed to perform input and output operations on sequences of character, like files or strings.This functionality is provided through several related classes, as shown in the following relationship map, with the corresponding header file names on top:
