"in program arrays12.java a swap method is called. does the swap method exchange parameter values x and y?"

1 answer:

6 0

<h2>Yes the swap method exchange parameter values if passed by reference or the value gets changed inside the function.</h2>

Explanation:

Since the program is not given, I will try to guide you about the mode of parameters.

The meaning of swap is interchanging the values. It can be done by using temporary variable or without using it (if the values are integers).

While passing the parameters, there are two ways, call by value/pass by value and call by reference/ pass by reference.

If call by value, then the value gets swapped only inside the function and will not reflected in the calling portion. Call by reference is other way round.

What is likely to happen to the economy when there’s too much money or credit circulating?

Svetlanka [38]

It depends on HOW much money is circulating. If governments just print money with nothing to back it, hyperinflation occurs. If there's a bit too much money and credit, inflation happens. Generally, 3% inflation is considered normal and a healthy amount by economists.

For this lab you will do 2 things:

zepelin [54]

Answer:

Here is the Python program:

COOKIES_PER_BAG = 40 #sets constant value for bag of cookies

SERVINGS_PER_BAG = 10 #sets constant value for serving in bag

CALORIES_PER_SERVING = 300 #sets constant value servings per bag

cookies = int(input("How many cookies did you eat? ")) #prompts user to input how many cookies he or she ate

totalCalories = cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG)); #computes total calories consumed by user

print("Total calories consumed:",totalCalories) #displays the computed value of totalCalories consumed

Explanation:

The algorithm is:

Start
Declare constants COOKIES_PER_BAG, SERVINGS_PER_BAG and CALORIES_PER_SERVING
Set COOKIES_PER_BAG to 40
Set SERVINGS_PER_BAG to 10
Set CALORIES_PER_SERVING to 300
Input cookies
Calculate totalCalories: totalCalories ← cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG))
Display totalCalories

I will explain the program with an example:

Lets say user enters 5 as cookies he or she ate so

cookies = 5

Now total calories are computed as:

totalCalories = cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG));

This becomes:

totalCalories = 5 * (300/40/10)

totalCalories = 5 * (300/4)

totalCalories = 5 * 75

totalCalories = 375

The screenshot of program along with its output is attached.
