General Concepts; Modular approach; Clarity and Simplicity of Expressions, Use of proper

Names for identifiers, Comments, Indentation; Documentation and Program Maintenance;

Running and Debugging programs, Syntax Errors, Run-Time Errors, Logical Errors; Problem Solving Methodology and Techniques: Understanding of the problem, Identifying minimum number of inputs required for output, Step by step solution for the problem, breaking down solution into simple steps, Identification of Arithmetic and logical operations

required for solution, Using Control Structure: Conditional control and looping (finite and





Getting Started:


C++ character set, C++ Tokens (Identifiers, Keywords, Constants, Operators), Structure

of 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; standard input/output operations from C language: gets(), puts() of stdio.h header file


Data Types, Variables and Constants:


Concept of Data types; Built-in Data types: char, int, float and double; Constants:

Integer Constants, Character Constants (Backslash character constants - \n, \t ), Floating

Point Constants, String Constants; Access modifier: const; Variables of built-in data types,

Declaration/ Initialization of variables, Assignment statement; Type modifier: signed, unsigned, long


Operators and Expressions:


Operators: Arithmetic operators (-,+,*,/,%), Unary operator (-), Increment and Decrement

Operators (--,++), Relational operators (>,>=,<,<=,==,!=), Logical operators (!,&&,||), Conditional operator: <condition>?<if true>:<else>; Precedence of Operators;

Expressions; Automatic type conversion in expressions, Type casting; C++ shorthand’s

(+=, -=, *=, /=, %=)




Flow of control:


Conditional statements: if-else, Nested if, switch..case..default,Nested switch. Case,break statement (to be used in switch..case only); Loops: while, do - while , for and Nested loops


String Functions:


Header File: string.h


Function: isalnum(), isalpha(), isdigit(), islower(), isupper(), tolower(), toupper();


Character Functions:


Header File: ctype.h


Functions: isalnum(), isalpha(), isdigit(), islower(), isupper(), tolower(), toupper(),

strcpy(), strcat(), strlen(), strcmp(), strcmpi();


Mathematical Functions:


Header File.math.h, stdlib.h;


Functions: fabs(), log(), log10(), pow(), sqrt(), sin(), cos(), abs(),


Other Functions:


Header File- stdlib.h;


Functions: randomize(), random()


User Defined Functions:


Defining a function; function prototype, Invoking/calling a function, passing arguments to

function, specifying argument data types, default argument, constant argument, call by

value, call by reference, returning values from a function, calling functions with arrays,

scope rules of functions and variables; local and global variables;


Structured Data Type: Array



Declaration/initialization of One-dimensional array, Inputting array elements, Accessing

array 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



Two-dimensional Array :


Declaration/initialization of a two-dimensional array, inputting arrAy elements Accessing

array elements, Manipulation of Array elements (sum of row element, column elements,

diagonal elements, finding maximum/minimum values);


User-defined Data Types:


Need for User defined data type: Defining a symbol name using typed of keyword and defining a macro using #define directive




Defining a Structure, Declaring structure variables, Accessing structure elements, Passing

structure of Functions as value and reference argument/parameter, Function returning structure, Array of structures, passing an array of structure as an argument/ a parameter to a function.



Time: 3hours

Total Marks: 30


1. Programming in C++

One programming problem in C++ to be developed and tested in Computer during the

examination. Marks are allotted on the basis of following:


Logic :

Documentation/Indentation :

Output presentation


2. Project Work


Problems related to String, Number and Array manipulation;

General Guidelines : Initial Requirement, developing an interface for user (it is advised to

use text based interface screen), developing logic for playing the game and developing

logic for scoring points.


i). Memory Game : A number guessing game with application of 2 dimensional arrays

containing randomly generated numbers in pairs hidden inside boxes.


ii). Cross ‘N Knots Game : A regular tic-tac-toe game


iii). Hollywood/Hangman: A word Guessing game
