C# Answers

a) Write a method PopulationTotal that accepts 2 positive values, namely the current

population and the growth rate . The method determines and returns the total population based on the current

population and growth rate.

b) Write a method Over180Million that accepts a positive value representing the population. The method determines whether the population is over 180 million people, and returns

a value of true if this is so, otherwise returns a value of false.

c) Write a program that requests the user for a year (you can assume the year will always be at

least 2000), the population of Brazil in that year and the annual

population growth rate (always as a real number in the range 0 – 1), and then uses the two

methods written above to determine and display the year in which Brazil’s population first

exceeded/exceeds 180 million people. The program must also display Brazil’s total population

in this year.

a) Write a method GetOneStudent that asks a student for both of his/her WRAV101 and

WRSC111 marks (each as a real number). The method must return both of these marks. The

method must ensure that each of the marks is in the range 0 to 100.

b) Write a method CanContinue that takes as input two marks, one for WRAV101 and one for

WRSC111. Each of these marks is in the range 0 to 100. The method must return the value

true if both of these marks are at least 50, otherwise the method must return the value false.

c) Write a method DisplayDecision that takes as input two marks, one for WRAV101 and one

for WRSC111. Each of these marks is in the range 0 to 100. If the student can continue with

the second semester modules (use CanContinue above), an appropriate message and the

average mark for the two modules is displayed, otherwise the student is informed that he may

not continue.

WRSC111. Each of these marks is in the range 0 to 100. The method must return the value

true if both of these marks are at least 50, otherwise the method must return the value false.

create a console application to test usage of switch case construct. Accept some integer from user as command line argument and using a switch case construct

Make a program that will accept an integer and loop for the same number of times as that of the inputted integer and input random integers and add it to the array/list one by one, per line. Afterwards, make your program accept another random integer.

Using that final integer, compare from your array/list if the final integer's value is also present in your current array/list. If so, print "Present"; otherwise, print "None".

If the monthly home loan repayment is more than a third of the user’s gross monthly

income, the software shall alert the user that approval of the home loan is unlikely.

7. The software shall calculate the available monthly money after all the specified deductions

have been made.

8. The software shall not persist the user data between runs. The data shall only be stored in

memory while the software is running.

Non-functional requirements:

1. You are required to use internationally acceptable coding standards. Include

comprehensive comments explaining variable names, methods, and the logic of

programming code.

2. You are required to use classes and inheritance. Create an abstract class Expense, from

which HomeLoan, etc., can be derived.

3. Store the expenses in an array

The first line will contain a message prompt to width of the skyscraper.

The second line will contain a message prompt to height of the skyscraper.

The succeeding lines will contain the skyscraper pattern.
