If I was taking this test, this would be my response:
There is only one solution. Fix the bug in the code by switching to
increment. Then move on to the next problem. Don't waste time with
trivial issues. Or, if you just have to print 20 '-'s, use a single
printf() and no for-loop. Intel: Go buy Safe C++ Design Principles and
learn how to write software.
Answers:
int i, n = 20;
for (i = 0; i < n; n--)
printf("-");
int i, n = 20;
for (i = 0; -i < n; i--)
printf("-");
int i, n = 20;
for (i = 0; i + n; i--)
printf("-");
All three answers are terrible. Don't do this in production code. Ever.
