Allisa [31]

Answer:

The solution code is written in Python 3

  1. SPY = float(input("Enter SPY Amount: "))
  2. QQQ = float(input("Enter QQQ Amount: "))
  3. EEM = float(input("Enter EEM Amount: "))
  4. VXX = float(input("Enter VXX Amount: "))
  5. totalAmount = SPY + QQQ + EEM + VXX
  6. print("Total amount invested: $" + str(totalAmount))
  7. print("Percentage invested for SPY: " + str(SPY / totalAmount * 100) + "%")
  8. print("Percentage invested for QQQ: " + str(QQQ / totalAmount * 100) + "%")
  9. print("Percentage invested for EEM: " + str(EEM / totalAmount * 100) + "%")
  10. print("Percentage invested for VXX: " + str(VXX / totalAmount * 100) + "%")

Explanation:

Firstly, let's declare four variables, SPY, QQQ, EEM and VXX and use input() function to prompt user to input the amount invested in each fund (Line 1 - 4).

Next, sum up all the funds' amount and assign the total to totalAmount variable (Line 6).

Next display the total amount invested and the percentage invested for each fund using print function (Line 7 - 11). Please note the formula to calculate the percentage of investment is

(fund / totalAmount ) * 100

What is the printout of the call nPrint("a", 4)?
satela [25.4K]

Answer:

aaaa

Explanation:

We have a function nPrint which return type is void, it means it returns nothing.

we declare the two parameters, one parameter is string type and the second parameter is an integer type.

Then, it has a while loop that executes the statement again and again until the condition not FALSE.

Let dry run the code:

First, call the function nPrint("a", 4) bypassing the value in the argument.

then, the value receives by the parameters, the message contains "a" and n contain 4. After that, while loop checks the condition 4 > 0, which is TRUE and the program starts executing the statement.

The program prints the message on the screen "a" and then decreases the value of n by 1. So, the value of n becomes 3.

The above process repeats for the value of n = 3, 2, 1

and print the message "aaaa".

then, the condition becomes false and the program terminates the loop.

Therefore, the answer is aaaa
