Part A – Mini -Project Proposal
" Contact management system"
1. Brief Introduction:
The "Contact Management System" has been developed to override the
problems prevailing in the practicing manual system. This software is
supported to eliminate and in some cases reduce the hardships faced by this
existing system. Moreover this system is designed for the particular need of
the company to carry out operations in a smooth and effective manner. The
application is reduced as much as possible to avoid errors while entering the
data. It also provides error message while entering invalid data. No formal
knowledge is needed for the user to use this system. Thus by this all it proves
it is user-friendly. Contact Management System , as described above, can
lead to error free, secure, reliable and fast management system. It can assist
the user to concentrate on their other activities rather to concentrate on the
record keeping. Thus it will help organization in better utilization of
resources. Every organization, whether big or small, has challenges to
overcome and managing the information of Credential, Contact, Profile,
Mobile, Emails. Every Contact Management System has different Contact
needs, therefore we design exclusive employee management systems that are
adapted to your managerial requirements. This is designed to assist in
strategic planning, and will help you ensure that your organization is
equipped with the right level of information and details for your future goals.
Also, for those busy executive who are always on the go, our systems come
with remote access features, which will allow you to manage your workforce
anytime, at all times. These systems will ultimately allow you to better
manage resources.

Part B – Mini -Project Report
1. Rationale:
The mini project 'Contact Management' is the sample project for
managing contact details. The project aims at developing contact
management system using the C language that enables an organization to
maintain its library. The project demonstrates the creation of a user
interface of a system, without the use of C Graphics library. The
application uses basic C function to generate menus, show message boxes
and print text on the screen. To display customized text with colors and
fonts according to application requirements, functions have been created
in the application, which fetch the exact video memory addresses of a
target location, to write text at a particular location. The application also
implements the concept of structures to define the contact items. It also
effectively applies the various C concepts such as file operations, looping
and branching constructs and string manipulation functions.
Control statement
C language possesses such decision making capabilities by supporting the
follow statements:
•If statement
•Switch statement •Conditional operator statement
These statements are popularly known as decision-making statements. Since
these statements 'control the flow execution, they are known as control
statements.
6
1. control statement
The if-statement is a powerful decision making statement and is used to
control the floexecution of statements. It is basically a two-way decision
statement and is used in conjunction with an expression. It takes the following
form:
If (test expression)
It allows the computer to evaluate the expression first and then, depending on
whether the value expression (relation or condition) is 'true' (or non-zero) of
false' (zero),it transfers the controlto a particular statement. This point of
program has two paths to folow, one for the true condition and the other for the
false condition as shown below:
The if statement may be implemented in different forms depending on the
complexity of conditions to be tested.the different forms are:
•Simple if statement
•If...else statement
• Nested if.....else statement Else if ladder.
2. Switch statement:C has a built-in multiway decision statement known as a switch. The
switch statement tests the value of a given variable (or expression) against a list
of case values and when a match is found, a block of statements associated with
that case is executed. The general form of the switch statement is as shown
below:
7
switch (expression)
{
case value-1:
block-1
break;
case value-2:
block-2
break;
....................
....................
default:
default-block
break;
}
statement-x:
The expression is an integer expression or characters.
value-1,value-2..are constants or constant expressions (evaluable to an integral
constant) und are known as case labels. Each of these values should be unique
within a switch statement. block-1.block-2.are Statement lists and may contain
zero or more statements. There is no need to put braces around these blocks.
Note that case labels end with a colon:).
3. Conditional operator statement:- The e language has an unusual operator,
useful for making two-way decisions. This operator is a combination of? And
takes three operands. This operator is popularly known as the conditional
operators. The general form of use of the conditional operator is as follows:
Conditional expression? expression1:expression2
The conditional expression is evaluated first. if the result is nonzero.expressionl
is evaluated and is retumed as the value of the conditional
expression.Otherwise.expression2 is evaluated and its value is retumed.

2. Course Outcomes Addressed:
1. To get an idea about making a simple project using C.
2. To be able to solve problems by compiling and Debugging.
3. To concise the memory of program as far as possible.
4. To be able to work in groups as a team sharing different
responsibilities.
5. To learn about the use of user defined function, structure, array and
data file in C.

4. Proposed Methodology:
9
The first and the most prominent step of establishing a contact
management system is to engage directly with the customer who is
seeking a solution to his/her problem through the product or service the
company is providing. Contact management can be initiated by
implementing one of the following ways.
 You can directly engage with the customer by asking him about the
products or services being promoted or advertised by the company.
 You can make cold calling, which includes calling up a particular
person and asking him whether he or she might be interested in the
new product or scheme inaugurated by the company.
 You can contact prospects by internal or external references, i.e.,
known acquaintances, relatives, or friends of a pre-existing customer.
 You can make prospects take online surveys and past track record of
the web surfing of the customers.
You can participate in online events and exhibition events where
potential customers can give their details and express their perspectives
about the product or service of a company.
When the lead has been created by acting upon the strategies
mentioned above, it is then time to build on the lead. It is strongly
recommended to know as much as possible information about the
preferences of a customer and try to acquire extensive knowledge about
how much money potential customer is willing to spend. It will convert a
customer into ever paying client.
Consistent engaging with the customers ensures the customer that an
organization pays special heed on providing value-added incentives.
Through direct interaction with the customer, company personnel can
guide their respected customers towards the official website of a
company, and utilize telephonic conversation to gain firsthand knowledge
about the needs of the customers.

6. Conclusion:
So far, we’ve discussed all the critical aspects of the contact management
automated system. So far, whatever has been said, it should be taken into
consideration that the success of any business, whether it is a large organization
or a small startup solely relies on the level of satisfaction of the customer.
Just because of these reasons, large organizations emphasize significantly on the
automated contact management system to reduce the company overhead and
enhance their revenue as an outcome.

8. Skill Developed/learning out of this Microproject:
 We learn about contact management system.
 We become able to develop a “Phonebook contact” application using c
programming.
9. Application of this Miniproject:
It may help collecting perfect management in details. In a very short time,
the collection will be obvious, simple and sensible. It will help a person
know the management of passed year perfectly and vividly. It also helps
in current all works relative to Contact Management System. It will be
also reduced the cost of collecting the management & collection
procedure will go on smoothly.
Our project aims at Business process automation, i.e. we have tried
to computerize various processes of Contact Management System.
• In computer system the person has to fill the various forms & number
of copies of the forms can be easily generated at a time.
•In computer system, it is not necessary to create the manifest but we can
directly print it, which saves our time.
•To assist the staff in capturing the effort spent on their respective
working areas.
•To utilize resources in an efficient manner by increasing their
productivity through automation.
22
• The system generates types of information that can be used for various
purposes.
• It satisfy the user requirement.
•Be easy to understand by the user and operator.
•Be easy to operate Have a good user interface.
•Be expandable Delivered on schedule within the budget.
10. Area of Future Improvement:

It becomes even difficult to store contacts with two or more contact
numbers.

It becomes easy for the user to store complete information (e-mail id,
address,e.t.c) about his contact.
