  Course objectives: • Tounderstand basic programming constructs and use the newly acquired skills to solve extensive programming problems. • To understand the principles of the object-oriented model and its implementation in the ‘C++' language. • To build on the concepts learned in C language and use the power of object oriented programming to develop software applications. • To enable the students to write and execute well structured 'C++' programs. • To use problem solving and program design techniques effectively to generate applications.

  Lab work Submission: •Lab work due must be submitted online before midnight next class – No explicit submission allowed. • No extension in deadline is Allowed. • Late assignments incur 10% per day penalty up to 3 days. After 3 days, no credit. • Under special circumstances, you may be excused from an assignment or quiz. Must inform ahead of time. • Only Original Work will be considered, copying is strictly disallowed.

  History of C++:
• 9.
  Features of C++: •C++ is a general-purpose Object-Oriented Programming (OOP) language • C++ is a middle-level programming language • It is an extension of the C language and has Improved many of C's features • C++ runs on different operating platforms such as Windows, Macintosh OS, and different versions of UNIX. • Increases software quality and reusability • It was Developed by Bjarne Stroustrup at Bell Labs Called "C with classes“ an enhanced version of C.

  Problems with StructuredProgramming: • Procedural Languages: • Division into Functions • Unrestricted Access • Real-World Modeling • Attributes • Behavior Global and local variables: The procedural paradigm
• 11.
  The Object-Oriented Approach: •The fundamental idea behind object-oriented languages is to combine into a single unit both data and the functions that operate on that data. Such a unit is called an object. • An object’s functions, called member functions in C++, typically provide the only way to access its data. If you want to read a data item in an object, you call a member function in the object. It will access the data and return the value to you.You can’t access the data directly. • The data is hidden, so it is safe from accidental alteration. Data and its functions are said to be encapsulated into a single entity. Data encapsulation and data hiding are key terms in the description of object-oriented language

  OOP: An Approachto Organization:
• 13.
  Characteristics of Object-OrientedLanguages: • Objects: Objects are referred to as the basic run-time entities. • Classes: Class is a collection of objects of the similar type. • Inheritance: When the objects of one class acquire the properties of the objects of another class, it is referred to as inheritance. • Base Class: The class in which the members are inherited (by objects of another class) is called the Base class. • Derived Class: The class that inherits the members is called the Derived class. • Encapsulation: Encapsulation means to “wrap up” the functions and data into a single class.
• 14.
  … • Abstraction: Data abstractionmeans to show only required information and hide the remaining information • Reusability: A class once written, created and debugged, it can be distributed to other programmers for use in their own programs • Creating New DataTypes: It is possible to construct new data types • Polymorphism and Overloading: Using operators or functions in different ways, is called polymorphism. When an existing operator is given the capability to operate on a new data type, it is said to be overloaded. Overloading is a kind of polymorphism; it is also an important feature of OOP.
