Suppose you want to write an if statement with multiple alternatives to print out someone's tax bracket based on their income. A

ssume the integer variable income holds the annual income. What is wrong with the following if statement?if (income < 10000)
{
System.out.println("Lowest tax bracket");
}
if (income < 20000)
{
System.out.println("Low-Middle tax bracket");
}
if (income < 30000)
{
System.out.println("Middle tax bracket");
}
System.out.println("High tax bracket");

a) The conditions are in the wrong order; the check for the highest bracket should be first
b) The conditions should use an if else/if else sequence, not just independent if statements
c) The conditions should be a switch statement instead
d) Nothing is wrong - the if statement will correctly print out the tax brackets

"Write an iterative function iterPower(base, exp) that calculates the exponential baseexp by simply using successive multiplicat
sp2606 [1]

Answer:

I am writing the function using Python. Let me know if you want the program in some other programming language.            

def iterPower(base, exp):    

    baseexp = 1

    while exp > 0:

        baseexp = baseexp*base

        exp= exp - 1

    return baseexp

base = 3

exp = 2

print(iterPower(base, exp))

Explanation:

  • The function name is iterPower which takes two parameters base and exp. base variable here is the number which is being multiplied and this number is multiplied exponential times which is specified in exp variable.
  • baseexp is a variable that stores the result and then returns the result of successive multiplication.
  • while loop body keeps executing until the value of exp is greater than 0. So it will keep doing successive multiplication of the base, exp times until value of exp becomes 0.
  • The baseexp keeps storing the multiplication of the base and exp keeps decrements by 1 at each iteration until it becomes 0 which will break the loop and the result of successive multiplication stored in baseexp will be displayed in the output.
  • Here we gave the value of 3 to base and 2 to exp and then print(iterPower(base, exp)) statement calls the iterPower function which calculates the exponential of these given values.
  • Lets see how each iteration works:
  • 1st iteration

baseexp = 1

exp>0 True because exp=2 which is greater than 0

baseexp = baseexp*base

               = 1*3 = 3

So baseexp = 3

exp = exp - 1

      = 2 - 1 = 1    

exp = 1

  • 2nd iteration

baseexp = 3

exp>0 True because exp=1 which is greater than 0

baseexp = baseexp*base

               = 3*3 = 9

So baseexp = 9

exp = exp - 1

      = 1-1 = 0    

exp = 0

  • Here the loop will break now when it reaches third iteration because value of exp is 0 and the loop condition evaluates to false now.
  • return baseexp statement will return the value stored in baseexp which is 9
  • So the output of the above program is 9.

3.What are the pros and cons of using a linked implementation of a sparse matrix, as opposed to an array-based implementation
weqwewe [10]

Answer:

speed and storage

Explanation:

The pros and cons of both are mainly in regards to speed and storage. Due to linked lists elements being connected to one another it requires that each previous element be accessed in order to arrive at a specific element. This makes it much slower than an array-based implementation where any element can be quickly accessed easily due to it having a specific location. This brings us to the other aspect which is memory. Since Arrays are saved as a single block, where each element has a specific location this takes much more space in the RAM as opposed to a linked implementation which is stored randomly and as indexes of the array itself.

Array Implementation:

  • Pros: Much Faster and Easier to target a specific element
  • Cons: Much More Space needed

Linked Implementation

  • Pros: Less overall space needed
  • Cons: Much slower speed.

Write the pseudocode for a function named timesTen that accepts an Integer argument. When the function is called, it should retu
iren [92.7K]

Answer:

function timesTen (number):

   return number * 10

n = int(input("Enter an integer: "))

print(str(n) +"x10 is equal to: " + str(timesTen(n)))

Explanation:

Pseudocode is the representation of an algorithm. It shows the steps of the algorithm combination of the English and programming language.

In the pseudocode, we said we will be defining a function called timesTen that takes one parameter and returns the value of its parameter multiplied times 10.

In the main, we asked the user to enter a number. Then, we called the function with that number, and print the result.
