This document provides an overview of unit-III programming using C/C++. It discusses the objectives of learning fundamental problem solving techniques, program design, and the C++ programming language. It then defines C++ as a programming language that allows a computer program to perform specific tasks and interact with users and hardware. It also lists some of the most popular programming languages and the most common versions of C++. The document notes that while C++ is not easy to learn, it provides good job opportunities and experience that can help with learning other languages like Java. It outlines some of the industries that use C++ and emphasizes C++'s strong support for structured and object-oriented programming across different operating systems. Finally, it describes some

1. Unit-III Programming
using C/C++
 -Dr. Piyush Charan
 Assistant Professor, Dept of ECE, Integral
University, Lucknow

2. Objectives
✘ To learn fundamental problem solving techniques
✘ To learn how to design a program
✘ To learn to use the C++ programming language

3. What is C++?
✘ C++ is a programming language.
✘ A computer program performs a specific task, and may interact with the user
and the computer hardware.
✗ Human work model:
✗ Computer work model:

4. What is C/C++?
✘ The most popular programming languages:
✗ Basic (Beginner All-purpose Symbolic Instructional
Code)
✗ C++ (an object-oriented language, based on C)
✗ Cobol (Common Business Oriented Language)
✗ Fortran (FORmula TRANslation)
✗ Java
✗ Pascal (named for Blaise Pascal)
✗ Visual Basic (Basic-like visual language developed by
Microsoft)
✗ C (developed by the designer of the B language)
✘ The most common versions of C++:
✗ Microsoft VC++2008
✗ Eclipse
✗ g++ (for Unix machines)

5. Why C/C++?
✘ Bad News:
✗ C++ is not easy to learn
✘ Good News:
✗ Lots of good-paying jobs for programmers because C/C++ is
not easy to learn!
✗ Java uses C++ syntax, it is easy to learn Java if you know C++.
✗ Though C++ is not the easiest language (Basic and Pascal are
easier), it is not the hardest either (Ada, Prolog and Assembly
languages are really difficult!)

6. Who Uses C/C++?
✘ Computer makers such as TCS, Microsoft, IBM, Infosys and HP
✘ Airport
✘ Computer chip manufacturers
like Motorola & Intel
✘ Software companies
✘ Banks
✘ Government
✘ Hospital Authority
✘ Telecommunications
✘ Universities

7. Most Important Feature of C/C++
✘ Most important feature of C++: its strong and efficient
support of both Structured Programming and Object-
Oriented Programming.
✘ C/C++ runs on:
✗ PC
✗ Macintosh
✗ Unix workstations (also, Unix versions of C++ are
free!)
✗ supercomputers

8. What Can We Do
By the End of the Course?
 Program the computer in applications such as the following:
 Program a simple calculator
 Program simple computer games
 Program a simple text editor
 Program a small inventory system for a small company
 You will be ready to take on part-time programming jobs by the end of
the semester!
