Answer 1

The answer to the first program is

d. loop control variable never resolves to true

int i = 100; //loop control variable is initialized and declared here

while(i < 10) //loop control variable never resolves to true

i++; //loop control variable is updated here

The answer to the second program is

a. nothing is wrong with this code.

int i = 1; //loop control variable is initialized and declared here

while(i < 10) //loop control variable resolves to true here

i++; //loop control variable is updated here
