Question
Objective:
This assignment is designed to learn programming in VB.NET.
Questions:
(2 marks) In Visual Studio, create a VB.NET Console Application that does the following:
Create three variables of String data type, called firstName, lastName, and fullName respectively;
Assign your first name to the variable firstName;
Assign your last name to the variable lastName;
Concatenate the variable firstName, a string containing a space (i.e., “ ”), the variable lastName together, and then assign the result to the variable fullName;
Display your name in the console window using the statement Console.WriteLine(fullName)
(3 marks) In Visual Studio, create a VB.NET Console Application that does the following:
Create a variable of Integer data type, called marks;
Create a variable of String data type, called grade;
Assign 88 to marks;
Convert marks into grade as follows using the Select-Case statement:
marks
grade
90-100
A+
85-89
A
80-84
A-
77-79
B+
73-76
B
70-72
B-
67-69
C+
63-66
C
60-62
C-
50-59
D
0-49
F
(5) Display the values of marks and grade in the console window using the statements
Console.WriteLine(marks)
Console.WriteLine(grade)
(2 marks) Repeat Question 2 using the If-Then-ElseIf statement (instead of the Select-Case statement). Your output should be exactly the same as that of Question 2.
(3 marks) In Visual Studio, create a VB.NET Console Application that uses the While loop to display all leap years between 2017 and 2050. A leap year between 2017 and 2050 is a year that is an integer multiple of 4 (i.e., year Mod 4 = 0). For example, 2020 and 2040 are leap years. (Hint: you need both the While and If-Then statements.)
For each question, print the program and handwrite the output at the end of the printout of the program.
