QUESTION 13
Assume j, i, n, and max have been declared. Use the following code to answer the questions that follow:
j
3;
k = 1;
n = 2;
max = 21;
while (n < max)
{
'#');
System.out.printf("%c",
n = n + j - k;
}
1) What is the loop control variable?
2) What is the value of n in the test expression before the first iteration of the loop?
3) In the first iteration, what is the value of n after the assignment statement ( n = n + j
k; )?
4) How many '#' symbols will be displayed by this code?
5) What value stored in n causes the loop to stop?
