My program needs to recognize character expressions such as: a> 11&&a <100&&b == 15 || c> 21&&d == 20, and the program finally returns a true or false value, such as the function bool bret = fun (String s); s is a> 1&&a <100&&b == 5 || c> 1&&d == 2 and other strings, there may be +-* / (), etc., this How to deal with it?
Thank you |
