Question

4. Perform a hand trace by producing a table of values for each of the variables in the following program. Similar to what you did in one of your labs. Note: Any computer generated output will be awarded a grade of zero. {4 points) #include <iostream> using namespace std; int main() { int low high; low = 1; high = 20; while (low < high) | cout << low << " " << high << endl; low = low + 1; high = high - 1; } // end while }// end main

Answer 1

Iteration #	low	high	low < high	output
1	1	20	true	1 20
2	2	19	true	2 19
3	3	18	true	3 8
4	4	17	true	4 17
5	5	16	true	5 16
6	6	15	true	6 15
7	7	14	true	7 14
8	8	13	true	8 13
9	9	12	true	9 12
