Case 1: QTest is an advertising company that is approached by big organisations such as ABCL and softCom to conduct quizes for advertising their products. For conducting quizes, QTest first asks different individuals to register by specifying details such as their name and surname.

After individuals get registered, QTest selects some individuals from a group of individuals and invites them to participate in the quiz. The task of obtaining details from different individuals is so far performed manually by a group of QTest staff. However, manually performing the task of obtaining details from different individuals is time consuming.

QTest has to employ additional staff for performing the task of getting details from individuals.

As a result, QTest is facing financial loss in the advertisement business. How can QTest automate the task of receiving details such as the name and surname from individuals for registration?

Solution:

QTest needs to use an application created in a programming language such as C# to automate the task of obtaining details from individuals for registration.

After having decided that it needs an application for automating the task, QTest contacts ADev Software Solutions Private Limited, which is a small software development company, to create the application for automating the task Of obtaining details from individuals. After an analysis of the requirement, ADev creates a C# application using the string methods such as Insert and Append available in C#.

These string methods allow us to perform different manipulation tasks such as appending a string to another string and inserting a string. The following C# application is ultimately created by ADev Software Solutions for QTest.

Case 2: Mr. Harish owns a two storied house in B.N. Colony, Ahmedabad. He has to pay the property tax for the house every year to the Municipal Corporation of the city. Currently, Mr.Harish has been manually calculating the property tax each year using a calculator. As a result, errors occur during calculation and Mr. Harrish is not able to pay the tax on time. Mr. Harrish also needs to spend a large amount of time while manually calculating the property tax for his house.

This too delays the payment of property tax to the Municipal Corporation of the city. If the property tax is not paid on time, the Municipal Corporation levies a late fee of R0. 2000. What must Mr. Harrish do to avoid delay in the payment of property tax?

Solution

After a lot of research, Mr. Harrish comes to the conclusion that he should have a software application installed on his Home PC that helps in automating the task of calculating property tax. He, therefore requests his neighbour, Mr Gautam who is a software professional, to spare some hours for him, to create an application for him so that the task of calculating property tax is automated.

After analyzing the requirements of Mr Harrish, Gautam decides to use the method overloading feature of C# in the application for automating the task of calculating property tax. Method overloading is an important feature of C# that allows you to use the same name for multiple methods. Gautam then creates the following c# application for Mr Harrish
