Which of the following is an object-oriented language?
A. C
B. C++
C. BASIC
D. COBOL
Answer:
C++
Explanation:
Significant object-oriented languages include: (list order based on TIOBE index) Java, C++, C#, Python, R, PHP, Visual Basic.NET, JavaScript, Ruby, Perl, Object Pascal, Objective-C, Dart, Swift, Scala, Kotlin, Common Lisp, MATLAB, and Smalltalk.
The programs' structure is made obvious via OOP. OOP makes the C++ code easier to maintain, alter, and debug by encouraging “Don't Repeat Yourself” (DRY) programming practices. OOP allows for quicker development times and less code needed to create fully reusable apps. Thus, option B is correct.
What role of C++ as an object-oriented language?The following are several justifications for calling C++ a partial or semi-object oriented language. The primary action is not a class action.
Object-oriented programming is supported by C++, but it is not a feature of the language itself. You don't even need to use an object once to construct a legitimate, well-coded, and brilliantly styled C++ program.
Therefore, Object-oriented programming can be implemented using C++'s core features. It contains classes and objects as well as the OOP principles of inheritance, encapsulation, abstraction, and polymorphism. It also has access to specifiers.

conditions.
Answer:
Explanation:To get the best plant growing conditions, the temperature and humidity (moisture in the air) have to be controlled.
The greenhouse therefore has temperature and humidity sensors linked to a computer, and the computer has a control program storing details of the correct temperature and humidity settings. The greenhouse is fitted with a heater, sprinkler and window motor which are also linked to the computer.
If the humidity falls below the values stored in the program, the computer activates the sprinklers and closes the windows. If the temperature falls outside the values stored in the program, the heater is activated by the computer.

public static void main(String[] args) {
int numTwenties,numTens,numFives,numOnes,dollarAmount;
Scanner sc= new Scanner(System.in);
System.out.println("Please enter a dollar amount: ");
dollarAmount = sc.nextInt();
numTwenties = dollarAmount/20;
numTens = (dollarAmount - 20*numTwenties)/10;
numFives = (dollarAmount - (10*numTens + 20*numTwenties))/5;
numOnes = (dollarAmount - (10*numTens + 20*numTwenties + 5*numFives));
System.out.println(+ dollarAmount + " converted is" + numTwenties + " $20s, " + numTens + " $10s, " + numFives + " $5s, and " + numOnes + " $1s.");
}
}
This is what it is giving me -

Write pseudocode for washing a car using at least five steps.
Answer:
Step 1: Prepare the Cleaner
Pour a capful of car wash cleaner into a bucket and fill it a little over halfway with tap water. Car wash soap is specially designed to clean a car's exterior surfaces without stripping off wax, and it is typically sold alongside wax and car-detailing products in stores. Toss the first sponge in the bucket to let it soak up water and cleaner.
Step 2: Use the Garden Hose First
Spray water all over the car, starting at the top and working down the body of the car.
Step 3: Wash the Roof
Wash the top of the car first by squishing most of the excess water out of the sponge, then begin washing. Rinse the top as soon as you finish to ensure that the cleaning product does not dry on your car's paint. Blot the excess water off with your chamois or a terry cloth towel.
Step 4: Wash the Car's Body
Wash the car's body in sections, one panel at a time. Spray each panel with the garden hose again before washing with the sponge and cleaner. Rinse immediately after washing.If the water is not drying too fast, complete one whole side of the car before drying. If the water is drying quickly, dry each panel as soon as you finish washing.
Step 5: Wash the Wheel and Tires
Spray the wheel and tire cleaner on the wheels and tires.Using the second sponge, a brush or a rag, rub the cleaner into the tires to remove any remaining road dirt.
Step 6: Drying Your Car
Check your product's label to see if it needs to be washed off with water or buffed with a clean rag to complete the project.
