而c++必须是当前语句执行晚后才把c+1，之前都是按照原来的c的值算得 至于这个当前语句执行完，也就是碰到 ' ; ' , ' } ' , ') '时
denote postfix-decrement operator and –x; denote prefix decrement operator. Having seen the difference with respect to notation now let us see the difference between both prefix and postfix with respect to functionality. The prefix increment operator adds one to its operand. This incremented value...

If the target language uses prefix and postfix operators, the problem is nontrivial. This paper shows how to unparse expressions using a simple, bottom-up tree walk, which keeps track of the least tightly binding operator not enclosed by parentheses. During the tree walk, this operator is ...
C++ provides prefix and postfix increment and decrement operators; this section describes only the postfix increment and decrement operators. (For more information, seePrefix Increment and Decrement Operators.) The difference between the two is that in the postfix notation, the operator appears afterpos...
SAZZAD-AMT / Infix-to-Prefix-to-Postfix-Conversion-Assembly-code-by-c-program Star 2 Code Issues Pull requests While we use infix expressions in our day to day lives. Computers have trouble understanding this format because they need to keep in mind rules of operator precedence and also ...
The difference between the two is that in the postfix notation, the operator appears after postfix-expression, whereas in the prefix notation, the operator appears before expression, for example x–; denote postfix-decrement operator and –x; ...
In many cases, C++ programmers can choose between prefix and postfix operators. For maximum efficiency, visibility and consistency, prefix operators are the best choice. There may come a time when the powers that be see the error of their ways and rename the language to “++C”. But until ...
