Course objectives To understand 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. © LPU :: CSE202 Object Oriented Programming

The hitch… The BURNING questions in mind… Oh no… Why another Programming Language ? What would we do with it, we already know C? Will it really help improve my programming skills? © LPU :: CSE202 Object Oriented Programming

A Better C C++ Improves on many of C's features Has object-oriented capabilities Increases software quality and reusability Developed by Bjarne Stroustrup at Bell Labs Called "C with classes“ an enhanced version of C Superset of C Can use a C++ compiler to compile C programs Gradually evolve the C programs to C++ Towards better programming…. © LPU :: CSE202 Object Oriented Programming
