Answer:
I am writing a C++ program. Let me know if you want the program in some other programming language. Here is the portion of the code:
if((userItem == GR_APPLES) || (userItem == GR_BANANAS)){
cout << "Fruit"; }
else if((userItem == GR_JUICE) || (userItem == GR_WATER)){
cout << "Drink"; }
else{
cout << "Unknown"; }
cout << endl;
Explanation:
The IF statement is used to check the defined options with the value in the userItem.
If the value of the userItem is GR_APPLES OR GR_BANANAS then Fruit is printed as the output. || represents a logical operator OR so this means that userItem can be either the GR_APPLES or GR_BANANAS for the If condition to evaluate to true.
If the above condition evaluates to false then the else-if part will be checked next. So the else if checks if the value in the userItem is GR_JUICE or GR_WATER. If userItem contains either of these two then Drink is displayed on the screen as output.
If the else-if statement also evaluates to false then the else part is executed which displays Unknown.
The cout<< endl; statement in the last is used to print the new line. For example if the output is Unknown then it is followed by a new line.
In the given program userItem is set to GR_APPLES
GroceryItem userItem = GR_APPLES
So the output of the whole program is Fruit followed by a new line.
The screenshot of the code along with the output is attached.

Answer:
C) someThing.someMethod( )
Explanation:
The methods in a class can be accessed outside the class (assuming they are public methods and not private to the class) by using the dot(.) symbol and calling the method on the instance or object of the class.
In this case, the object of the class someThing, calls the method, someMethod( ) by using a dot and the name of the method with a parentheses at the end. This enables the code in the method act on the class instance or object.
Answer:
Compression is hard since we usually find it difficult to determine the best compression rate .
When using the text compression widget we make a key that represent every work we have repeated in order to decrease the stored data.
When you have extends you compression beyond what it should be it is easy to notice since there will be no algorithm and that makes it hard hence we end up making assumptions on what ratio we will use for compression by using a thorough key.
