The following code is intended to test whether the int variable num is less than 10, and if so print a warning and set it to 10.
The code then prints the value of num.
if (num < 10)
System.out.println( "This is smaller than 10" );
num = 10;
System.out.println("Value of num is " + num);
What correction should be made so the code functions as intended?
An else statement should be added between the 3rd and 4th lines
The final line should be printed every time, not just when num hasn’t been changed.
A semicolon should be added at the end of the first line
The operator ‘<’ should be changed to ‘<=’ in the if statement
No correction should be made
Curly braces ‘{ }‘ should be added to enclose the second and third lines

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.
