I am new to clips software, when i loaded my .clp file and run my program at last it is showing false

Question

This is the expert system solving the car starting problem. Did i make any mistake in creating the rules. I want the output in 5 different.

Maybe ask your instructor? The CLIPS docs tell you how to debug your systems. — , Feb 22 '19 at 21:41

Since the last rule in your file, r32, loads without error there is probably something after that rule causing the issue. It might be an invisible character so you might try deleting any extra lines at the bottom of your file. See also CLIPS "Expected the beginning of a construct", CLIPS Expected beginning of construct, and expected the beginning of a construct error.

Thanks, It helped there is an extra character '-' after the last rule . When I load the program I get TRUE and when I Run then I do not see anything happening. Can you please help me how to fix it. This is my assignment have to submit by sunday night. – Archana Gurimitkala Feb 23 '19 at 12:19
Why do you expect something to happen? Can you identify one rule that you've written and explain why you think it should execute when you issue a run command? – Gary Riley Feb 23 '19 at 19:20
I just want to printout the question for the user to select yes or no for further process. My assignment question (Include samples of execution – a description of the problem you are interested in solving as well as the source code. Demonstrate its execution through screen dumps. You need to document at least five separate runs of your program) – Archana Gurimitkala Feb 23 '19 at 19:42
What should i do ? to print the questions to user . – Archana Gurimitkala Feb 23 '19 at 19:45
You have rules which ask questions but they all have conditions that need to be satisfied before they can execute. If you issue a (assert (engine light yes)) command before you issue a (run) command, you'll be asked questions. You need to look at each rule condition and see if there is another rule that asks a question and asserts a fact that can satisfy that condition. When you find a rule that has a condition that is not asserted by another rule, you need to add a rule that has no conditions that asks the questions and asserts a fact with the answer. – Gary Riley Feb 23 '19 at 23:22
Thanks a lot, I got my questions for the user by following your suggestions. I really appreciate your help. – Archana Gurimitkala Feb 24 '19 at 15:01
