Answer 6

w < 100 / cin&raquo_space; w

Question 7

how many times will the loop iterate if the input is 105 107 99 103

Answer 7

2

Question 8

a loop should sum all inputs, stopping when the input is 0. if the input is 2 4 6 0, sum shoiuld end with 12. what should xxx, yyy, and zzz be? choices are in the form XXX/ YYY/ ZZZ
