Practice Assignment : File Handling in C++

Dear Students

I am posting assignment on file handling for practice. Do attempt the questions given and you can test your understanding by attempting the same.


Assignment-1

Assignment-2

File Handling in C++

Dear students, Now that we have discussed about binary and text file in c++, I feel confident that you can develop the functions for various file operations mentioned below:

• Creating a text file
• Displaying contents of text file
• Creating Binary File
• Showing Contents of binary files
• Adding more records at the end of file (app mode)
• Updating binary files
• deletion of a record from file (2 file method)
• Modification of a record (using two files)
• insertion of a record in sequential file ( using 2 file)

Getting Started with C++

Dear students (Class XI),
This mind map is to help students who are starting with C++ Programming Language.

Introduction to C++

C++ originated with Bjarne Stroustrop. In the simplest sense, if not the most accurate, we can consider it to be a better C. Although it is not an entirely new language, C++ represents a significant extension of C abilities. We might then consider C to be a subset of C++. C++ supports essentially every desirable behavior and most of the undesirable ones of its predecessor, but provides general language improvements as well as adding OOP capability. Note that using C++ does not imply that your are doing OOP. C++ does not force you to use its OOP features. You can simply create structured code that uses only C++'s non-OOP features.

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.

HOLIDAYS HOMEWORK(2008-09)

Q1. Complete and submit a CD with programs and assignment register on following subtopics from the given list of programs:

• Series
• Structures
• Enumerated data types
• Macro
• Classes
• Constructors

The printout to be taken in school lab after the school reopens. Submit the practical file with above-mentioned programs by 10^th July ’2006.

Q2. Declare appropriate classes and design the menu for the project topics alloted to your group.

The Subprogram must be submitted on the CD.

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++

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
