Hello professor. I have a few questions here: 1. Regarding error messages, for the error messages provided in Sample Queries, if other error conditions are encountered, is there a template for the output error message? Or can I write my own error message such as "Please enter the correct Country Code". 2. Regarding case sensitivity, please tell me if there is case sensitivity. I think that by entering the information MALE, mALe, and mALE, you should get the correct information about male. Also for country code, Jpn should have the same effect as JPN. Is my understanding correct? Or does it mean that in the country code, only the all-capital JPN is correct, and in the gender, only Male is correct, and other information should output an error message such as "Please enter the correct gender"? Thank you.

Hi, I'll answer each part after the question ANONYMOUS wrote: I hope it's clear that I'm expecting the program to deal with other error states. Given that I've not told you what they are, I can hardly be pedantic about the error message. True? While your program will be tested automatically, it will be marked by a human (one of the lab demonstrators). If the error is caught and error message makes sense in the context, that'll get full marks for that test. The point of any program is to be helpful, though the first priority is not to print rubbish. So, if there is a real error, catching and commenting is the priority. However, if the user's request has an obvious interpretation, e.g. male == Male (or malE, if you wish), then, while not incorrect, it's not super helpful to call out an error. Cheers MichaelW 👨‍🎨

Hi Professor, Regarding Point 2, I am not getting any clarity.can you explain clearly what the program is expecting.does the real test cases test only with the format (Ex: Male) or (male /mAle/maLe) to treat them as same whicdh gives output or should they be treated as errors?

ANONYMOUS wrote: Hi What I was trying to indicate is that treating malE as an error is not wrong, but does make use of perfectly usable information, so would be worth less as an answer, therefore half marks for that question. Cheers MichaelW 👨‍🎨

Thank you for your reply Professor, But sorry still i could not get clarity regarding it.What i was asking is that the gender column will contain values only as Male/Female to check or it might also contains male/mAle/maLe something like that so that should we consider them as equal to Male.Same with country column as well.
