Operator Precedence: When an expression has more than one operator, C has to determine the order in which to execute them. This is called the "precedence." Precedence of some basic operators: ++, --,!, (unary -), (unary +)// increment, decremement, not, unary ops *, /, %// mult...
2. Grammatical_Analysis类:该类中定义了识别数字以及标识符的文法,其方法booleanisVar(String x)与boolean isNum(string x)分别来判断字符串是否是合法的标识符或者数字。 3. Lexical_Analysis类:词法分析类,该类中定义了所有可能出现的符号以及它们的类别号,并对源程序进行扫描,生成初始符号表。 4. Operator_Pre...

這個警告一律表示在使用運算子或運算子優先順序 (Operator Precedence) 可能會發生混淆。 範例 下列程式碼將產生出這個警告: 複製 void f(int x, int y ) { if (!x | y) { //code } } 若要更正這個警告,請使用其中一種方法,如下列程式碼所示: 複製 void fC(int x, int y ) { /* When chec...
表达式Expression=参与运算的常量和变量称为操作数Operand + Operator 运算符有优先级Precedence, *和/是同一优先级,+和-是同一优先级,*和/的优先级高于+和-, 等号的优先级比+和*都低。 运算符的结合性Associativity:+ - * /左结合,等号右结合。一个表达式中出现多个等号,不是从左到右计算而是从右到左计算。
