Answer to Question #253434 in C# for Dani

Question

An Islamic bank wants you to develop a Zakat Calculator for them. The calculator shall
take the input of the 1) name of zakat donor, 2) Bank_Balance, 3) zakat_amount. Create constructor
to initialize variables with default values which will be called on the time of object instantiation.
There should be a method named à ƒ ƒ ¢ € œCal_zakat()à ƒ ƒ ¢ €  which calculates the zakat of each donor and set in
zakat_amount. The program adds up the zakat of each donor hence calculating the total_zakat of the
bank. Use a à ƒ ƒ ¢ € œdisplay()à ƒ ƒ ¢ €  which displays not only the data of the donor but also the total amount of
zakat of the bank. It should keep in mind that the zakat will be calculated only if Bank_Balance is
greater than or equal to 20,000. (You should implement the concept of overloading, copy constructor
or overriding wherever it is applicable)
Note: Zakat will be calculated by the formula (Bank_Balance *2.5)/100
