"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.

When an IPv6 device with no pre-configured IPv6 address powers up, it can calculate a global 128-bit IPv6 address for itself usi
RSB [31]

Answer:

True

Explanation:

IPv6 Is a later version of IP addresses, used to solve the problem of the limited number of IPv4 addresses in the network.

Just like IPv4, IPv6 can also is configured to a device statically and dynamically. Dynamic IPv6 configuration could be a stateless autoconfiguration SLAAC, a stateless DHCPV6 or a stateful DHCPV6.

The IPv6 address is configured with a prefix and a prefix length and a EUI generated 64 bit interface or a random interface id by the device.

Authorized agent Confidentiality Integrity Encryption 6:53 PM ______ means that only people with the right permission can access
mojhsa [17]

Answer:

The answer is "Confidentiality"

Explanation:

Confidentiality alludes to shielding data from being gotten to by unapproved parties. All in all, solitary the individuals who are approved to do so can access delicate information. Imagine your bank records, You ought to have the option to get to them obviously, and representatives at the bank who are assisting you with an exchange ought to have the option to get to them, yet nobody else ought to. An inability to keep up Confidentiality implies that somebody who shouldn't have access has figured out how to get it, through deliberate act or coincidentally. Such a disappointment of Confidentiality, normally known as a breach  can't be helped. When the secret has been uncovered, it is highly unlikely to un-uncover it.

Assuming your bank records are posted on a public site, everybody can realize your bank account number, balance, and so forth, and that data can't be eradicated from their brains, papers, PCs, and different spots. Virtually all the significant security occurrences reported in the media today include loss of Confidentiality.

Thus, in summary, a breach of Confidentiality implies that somebody accesses data who shouldn't be permitted to.
