If a router is attached to a network with a base ip address of 198.10.0.0/20 and receives a packet addressed to 198.10.10.144, answer the following questions: a. what is the network mask used by the router? (in dotted decimal or binary) b. what is the network portion of the incoming packets ip address? c. what is the hardware address portion of the ip address? d. will the packet be forwarded into its base network?

Which of the following “invisible” marks represents an inserted tab?

Write a program that begins by reading in a series of positive integers on a single line of input and then computes and prints the product of those integers. integers are accepted and multiplied until the user enters an integer less than 1. this final number is not part of the product. then, the program prints the product. if the first entered number is negative or 0, the program must print “bad input.” and terminate immediately. next, the program determines and prints the prime factorization of the product, listing the factors in increasing order. if a prime number is not a factor of the product, then it

Given int variables k and total that have already been declared, use a while loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. thus your code should put 11 + 22 + 33 + + 4949 + 50*50 into total. use no variables other than k and total.
