The material contained in this chapter falls, roughly, into two categories: generating code for expressions and handling control-flow constructs.Expression evaluationis well explored in the literature. Discussions of how to handle control flow are rarer; much of the material on control flow in this...

Both effects, the side effect and the calculation of the return value, happen at the same time, namely when the pre- or postfix expression is evaluated. Sometimes people mistakenly believe that with a postfix increment the increment happens "afterwards", like in the following example: f(i++...

This package hosts an array of frequently used regex validations and regex expression evaluation functionalities. In general, String check encompasses last word check, middle word check, first word check, sentence validation, phone number validation, nam
