                                             Programming in C                                                    Practicum
Unit I BASICS OF ‘C’ LANGUAGE AND OPERATORS
Character set in ‘C’ – Key words and Identifiers – Data types –
Variables: Declaration, Assigning values to variables – Input and
Output functions [printf() and scanf()]– C Operators: Arithmetic,
Logical, Assignment, Relational, Increment/Decrement, Conditional
(ternary), Bitwise and Special operators

Unit II BRANCHING AND LOOPING STATEMENTS
Conditional Branching Statements: Simple if statement, if-else and
if-else-if ladder statement – Switch Case statement
Unconditional Branching Statements: goto, break & continue
statement-Entry Controlled Loops (while loop and for loop) – Exit
Controlled Loops (do-while loop)

Unit III ARRAYS AND STRINGS
Arrays: Definition and Need of array – syntax, declaration and
initialization of One Dimensional (1D), Two Dimensional (2D) arrays
Strings: Definition of string – syntax, declaration and initialization of
string variables, String handling functions: strlen(),
strcpy(),strrev(),strcat(), strcmp() – accessing strings using gets() and
puts() functions

Unit IV POINTER AND STRUCTURE
Pointer: Definition of a pointer – Pointer variable declaration and
initialization – applications of pointers
Structure: Basic template of a structure (syntax) – Structure Variable
declaration: within Structure template, after Structure template –Array
within structure and Array of structure (basic concepts only) –
Difference between array and structure

Unit V FUNCTIONS AND FILE MANAGEMENT USING ‘C’
Functions: Inbuilt functions – User Defined functions: Function
Prototype, Function Definition and Function Call – Call by Value method
– Call by Reference method
File management: Opening, Reading, Writing, and closing a file using
C programs
