CSE Object Oriented Programing Lecture #0 Let’s explore and move to “Better C” Ritika Sharma

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. 2/23/2019

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? 2/23/2019

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…. 2/23/2019
