I get the message c set but no used in function foo I tried reverseing the test as below thinking c would have to appear on the right side of at least one test but, I get the same error. foo() { char c; if('\n' != (c = getchar())) { /* more code here */ } } Is it simply the use of the compound statement structure that causes this?? Thanks in advance for the solution. - Zarth Arn
