  Introduction and Historyof C++  C++ is a programming language  It was developed by Dennis Riche at Bell’s Lab in 1971.  In C++, we can make new software or programs.  Program is a set of instructions, which performs any particular task.
• 11.
  Introduction and Historyof C++  Before C++, there were so many languages which were being used by the programmers like GW Basic, Pascal, and Fortran etc. But after the birth of C++, it becomes more famous than all other languages. So many of the programmers divorced the other languages and happily married with C++.
• 12.
  Features of CLanguage  C++ is middle level language.  C++ is case sensitive language.  C++ has compiler as a language translator.  C++ is hybrid language (Combination of structured as well as Object orientation paradigm)

  First Program ofC++ #include <iostream> using namespace std ; int main () { cout <<"Hello World... n " ; system ("PAUSE") ; return 0 ; }
• 14.
  Explanation of FirstProgram #: It is a preprocessor directive include: It is a name of directory iostream: Built-in file using : Keyword Namespace: For directory Std: library file int: data type main (): Entry point for every C++ / C program { // Open curly bracket of the main function cout: output stream <<: Operator system (“PAUSE”): Built-in Function }// Closing curley brackets

  Compile and Execute •For compilation press F9 • For compilation as well as execution press F10 • Compilation and Execution F11 • For saving the program go to file and click on save. • By default file is saved with the extension of .CPP.
• 16.
  Escape Sequences • Certainspecial characters are represented as escape sequences. • An escape sequence begins with a (backslash) followed by an alphanumeric character. • List of Escape Sequence characters • n New Line • t Horizontal tab • r Carriage return • ” Double quotes • ’ Single quote • a Alert • b Back space • f Form feed • v Vertical tab • Back Slash • ? Question Mark • 000 Octal Number • xhh HEXA decimal number
