C语言++表达式的求解探讨

C语言中的++运算符是一种特殊的运算符,其特殊性在于一个运算符包含两个操作,不同的编译器对这两个操作在复合表达式中的处理机制不同,而同一个编译器对其在程序中的不同位置也有不同的处理。教材中仅仅对++运算符作了最简单的介绍,并没有对++运算的左连接和右连接同时参与运算时的处理规则作介绍,本文对++运算在不同情况下的求解进行了深入研究,得出对++运算符的运算要根据一定的程序环境和编译器环境而定。

The Discussion on Finding the Solution of ++ Expression in the C Programming Language

The ++ operation is a kind of special operation in the C Programming Language, because one operator includes two operations, the different compiler has not the same principle to deal with the two operations of the ++ expression, and the same kind of compiler has different principle to resovle that when it is in the different place in the C Programming Language. The base step of sovling one ++ expression is only introduced simply in the book, but none of books and interrelated references is introduced about sovling the form of i++ and ++i when they appear in one expression in the same time. The paper deeply studies the principle of sovling the ++ expression in the different environment, and I find out that the ++ expression can be resoved correctly denpending on different place in the C programme and different C compiler.
