Hi Good afternoon, how to make the Asia as valid input

Question

in strcmp Char*a="asia"; User inputs examples: Asia,asiA,ASia etc.

Answer 1

Convert input to lower case before comparing.
More complex and costly alternative: use regex match with case insensitive flag.
(BTW, pls forget the "sir" part. That excludes all women.)

Answer 2

My bad i only copied it, from my messages i forgotten to edit it.
