Note : Exploring inside computer system in the computer lab class.
UNIT 2: INTRODUCTION TO C++
Getting Started :
C++ characterset, C++ Tokens (Identifiers, Keywords, Constants, Operators), Structureof a C++ Program (include files, main function), Header files - iostream.h, iomanip.h, cout, cin; Use of I/O operators(<< and >>), Use of endl and setw (), Cascading of I/O operators, Error Messages; Use of editor, basic commands of editor, compilation, linking and execution.
Data Types, Variablesand Constants:
Conceptof Data types; Built-in Data types: char, int, float and double;Constants: Integer Constants, Character constants - \n, \t, \b), FloatingPoint Constants, StringConstants; Access modifier: const; Variables of built-indata types, Declaration/Initialisation of variables, Assignment statement; Type modifier: signed, unsigned, long
Operator and Expressions :
Operators: Arithmetic operators (-,+,*,/,%), Unary operator (-), Increment (++) and Decrement (--) Operators, Relation operator (>,>=,<,<=,= =,!=), Logical operators (!, &&,||), Conditional operator:
<condition>? <if true>:<if false>; Precedence of Operators; Automatic type conversion in expressions, Type casting;C++ shorthands (+=, -=, *=, /=, %=)
UNIT 3: PROGRAMMING METHODOLOGY
GeneralConcepts; Modular approach; Clarity and Simplicity of Expressions, Use of proper Names for identifiers, Comments, Indentation; Documentation and Program Maintenance; Running and Debuggingprograms, Syntax Errors, Run-Time Errors, Logical Errors
Problem Solving Methodologies: Understanding of the problem, Identifying minimum number of inputsrequired for output, Writingcode to optimizing execution time and memory storage, step by step solution for the problem, breaking down solution into simple steps, Identification of arithmetic and logicaloperations required for solution, Control Structure: Conditional control and looping (finite and infinite)
UNIT 4: PROGRAMMING IN C++
Flow of control:
Conditional statements: if-else,Nested if, switch..case..default, use of conditional operator, Nested switch..case, break statement (to be used in switch..case only); Loops:while, do - while , for and Nested loops
Inbuilt Functions
Header file Categorization Header Function
| Standard input/output functions | File stdio.h | gets ( ), puts ( ) |

| User Defined Functions: | | itoa ( ), atoi ( ) |
Introduction to user-defined function and its requirements.
Defininga function; functionprototype, Invoking/calling a function,passing arguments to function, specifying argument data types, default argument, constant argument, call by value, call by reference, returning valuesfrom a function,calling functions with arrays, scope rules of functions and variables local and global variables.
Relating the Parameters and return type concepts in built-in functions.
Structured Data Type:
Arrays: Introductory to Array and its advantages.
One Dimensional Array : Declaration/initialisation of One-dimensional array, Inputtingarray elements, Accessingarray elements, Manipulation of Array elements (sum of elements, product of elements, average of elements, linear search, finding maximum/minimum value)
Declaration/Initialization of a String,string manipulations (counting vowels/ consonants/digits/special characters, case conversion, reversing a string,reversing each word of a string)
Two-dimensional Array
Declaration/initialisation of a two-dimensional array, inputtingarray elementsAccessing array elements, Manipulation of Array elements (sum of row element, column elements, diagonal elements, finding maximum/minimum values)
User-definedData Types: Introduction to user defined data types. Structure
Defininga Structure (Keyword Structure), Declaring structure variables, Accessing structure elements, Passing structureto Functions as value and reference argument/parameter, Functionreturning structure, Array of structures, passing an array of structure as an argument/ a parameterto a function
Defining a symbolname using typedef keyword and defining a macrousing #define directive.
