example of two classes that could be used to demonstrate

Hello,

I have troubles with me homework. Could you help me with it plea

IT 1050 – Programming Logic
Final Exam – Take Home Portion

32 Points

1.       (3 points) Explain inheritance in your own words.  Give an example of two classes that could be used to demonstrate inheritance (you do not need to write the code).  Why do we use inheritance?

 

2.       (3 points) Explain polymorphism in your own words.  Explain an example (you do not need to write code).

 

3.       (2 points) Write a loop that outputs i * 3 for i =10 to i = 4000.

 

4.       (3 points) Write a loop that outputs i / 2 for i =12345 to i> 1234.  Decrement by 300 each time through the loop.

 

5.       (3 points) Write an if…else-if….else statement that outputs the following for each given input:

Input                         Output
1                                  Math
2                                  Composition
3                                  History
4                                  Information Technology

6.       (3 points) Re-write problem 5 using a switch statement.

 

7.       (4 points) Write an if…else-if statement that outputs the following for each given input.  Use boolean operators to create compound conditions.

Input                                 Output
C# or VB                           Oracle
Android SDK                   Google
iOS or XCode                  Apple
Java and RedHat           Oracle
Java                                   Sun Microsystems

8.       (3 points) Create an array that stores the following string values: spicy, salty, bland, greasy, delicious.  Use a foreach loop to output all of the values.

 

9.       (8 points) Create a class for a Television

Add the following encapsulated properties (use Get and Set):
boolisOn
intcurrentChannel
string currentInput

 

Add the following methods:
public void turnOn() – set isOn to true and display “TV is on”
public void turnOff() – set isOn to false and display “TV is off”
public void setChannel (int channel) – if the TV is on, set currentChannel to channel.  Display “Current channel is set to “ +currentChannel
public void getInput() – return the value of currentInput
public void setInput(intnewInput) – set the value of currentInput to newInput

 

Create an instance of the TV class and demonstrate all of the methods.

 

se. It is Programming Logic (C#) homework. I would appreciate for any help.
