Computer Science : Project ( C++ )

I am posting this information because students have not decided about the project topics so far. This is to help them in deciding the same. students should feel free to share any other idea that comes to their mind. So far only three students have send their project topics for approval and I am waiting for more response from students in coming week.........

Project content (Class XII)

Project for class XII should ensure the coverage of following areas of curriculum:

a. Problem Solving

b. Data Structure

c. Object Oriented Programming in C++

d. Data File Handling

Theme of the project can be

• Any subsystem of a System Software or Tool

• Any Scientific or a fairly complex algorithmic situation.

• Business oriented problems like

• Banking,

• Library information system,

• Hotel management system,

• Hospital management system,

• Transport query system

• School Management Systems

• Result Processing
  

• LAB Management System (Chem. , Phy. Computer Lab etc)

• Pay Roll

• Quizzes/Games

• Tutor/Computer Aided Learning Systems

The aim of the project is to highlight the abilities of algorithmic formulation, modular programming, optimized code preparation, systematic documentation and other associated aspects of Software Development.

The assessment would be through the project demonstration and the Project Report, which should portray Programming Style, Structured Design, High Cohesion, Good documentation of the code to ensure readability and ease of maintenance.

USER DEFINED DATA TYPES : typedef

We have already seen a data type that is defined by the user (programmer): The structures. But in addition to these there are other kinds of user defined data types:

Definition of own types (typedef)

C++ allows us to define our own types based on other existing data types. In order

to do that we shall use keyword typedef, whose form is:

typedef existing_type new_type_name ;

where existing_type is a C++ fundamental or any other defined type and new_type_name is the name that the new type we are going to define will receive. For example:

typedef char C;
typedef unsigned int WORD;
typedef char * string_t;

Assignment : Structure in C++

Posting the assignment on structure (User defined Data type). The questions are to be done in assignment register.

User Defined Data Type in C++ : Structure

Structures in C++

A structure is a group of data elements grouped together under one name. These data elements, known as members, can have different types and different lengths. Structures are declared in C++ using the following syntax:

struct structure_name
{
member_type1 member_name1;
member_type2 member_name2;
member_type3 member_name3;
:
:
} object_names;

example :

    struct product 
    {
     int weight;
   float price;
    } ;

product apple;
product banana, melon;

Subtopics Covered

• Defining a Structure

• Declaring structure variables

• Accessing structure elements

• Passing structure to 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

Data Structures (1 D & 2 D Arrays)

Array

It is a static data structure. It is a homogeneous collection of data. The elements in the array are stored on consecutive memory locations. Array is also known as a subscripted variable, e.g., A[i] is i^th element of the array A (i.e., i is the subscript with variable A). As we know that the elements of the array are stored on consecutive memory locations, it becomes convenient to find out the address of memory location of i^th element, for given base address (address of first element) and W (i.e. the number of memory locations required by one element).

Different Operations on 1 D ARRAYS

• Creation
  
• Traversal
• Insertion
  
• Deletion
• Searching
• Linear
• Binary Search
• Sorting
• Bubble Sorting
• Selection Sorting
• Insertion Sorting
• Merging

Different Operations on 2 D ARRAYS

• Creation
• Printing (Traversal)
• Addition of two Matrix
• Difference Matrix
• Multiplication of Matrix
• Row / Col Sum
• Diagonal Sum
• Transpose Matrix

Assignment : 1D Array & 2D Array

Posting the assignment covering 1D and 2D Arrays. The functions are to be written in assignment register. This assignment will help in attempting questions in theory paper also.

Date Of Submission : 15th April, 2008
(Class XII C)

Binary Search Function (Presorted Array)

Function to Search for an element from ARR[10] by Binary Search Method. Binary search method can be applied on array only if it is sorted. This function assumes that array is arranged in ascending (increasing) order.
