讲解Turbo C程序中++和--运算符的若干方法

Instructing the Increment and Decrement Operators in Turbo C Programs

C程序设计语言中提供了两个特有的运算符 ,即自增运算符 ( ++ )和自减运算符 ( - - ) ,用于对变量加 1、减 1正确理解并使用这两个运算符对于编写C程序是很重要的 .本文介绍了讲解分析TurboC程序中的自增运算符 ++和自减运算符 - -的 3种方法 ,即语句分解法。

C programming language provides two special operators,the increment and decrement operators,for incrementing and decrementing variables.It is important to understand these two operators correctly to write good C programs.This paper introduces three ways to instruct and analyze increment operator + +and decrement operator - - in Turbo C programs:decomposing statement,independent evaluting expressions and illustrating the storage of variables.
