1. you need to write a loop that will repeat exactly 125 times. which is the preferred loop construct to use? a. while loop b. do while loop c. for loop 2. you need to write a loop that will keep reading and adding integers to a sum, until the sum reaches or exceeds 21. the numbers are all less than 20 and the sum is initially 0. which is the preferred loop construct to use? a. while loop b. do while loop c. for loop

1c

2b

Explanation:

a) A for loop is suitable to create counters.

b) You know you can read an integer at least once, so it's OK to evaluate your continuation expression at the end of the loop.

However, while(...) { } and do {} while(...) constructs are very similar.

answer; i believe the answer is (on both rear

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
