CS-4205 Programming and Problem Solving Using C

Implementation of C programming problems

SESSION 2009/2011

M.Sc. (CS), M.Sc. (IT) , MCA SEMESTER I

SCHOOL OF COMPUTER SCIENCE & IT,
DAVV, INDORE
Aim:

Main aim of this course is to understand and solve logical & mathematical problems through
C language and Flowchart. Strengthen knowledge of a procedural programming language. Design
and develop solutions to intermediate level problems using the C language. Further develop
your skills in software development using a procedural language.

Objectives:
The C language is a simple computer language designed to enable sophisticated object-
oriented programming. C is defined as a small but powerful set of extensions to the standard
ANSI C language. Its additions to C are mostly based on Smalltalk, one of the first object-
oriented programming languages. C is designed to give C full object-oriented programming
capabilities, and to do so in a simple and straightforward way.
Most object-oriented development environments consist of several parts:
    An object-oriented programming language
    A library of objects
    A suite of development tools
    A runtime environment
