The table below lists the C language operators in order of precedence and shows the direction of associativity for each operator. The primary operators have the highest precedence. The comma operator has the lowest precedence. Operators in the same group have the same precedence. ...

2.表达式array[i+j]和i+j[array]是不是相等? answer: No,the second one is the same as array[j] + i,jue to the precedence of the operators. (不相等,因为第二个相当于array[j]+i,由于操作符的优先性) 3.下面的声明试图按照从1开始的下标访问数组data,它能行吗? intactual_data[20];int*dat...
C Precedence And Associativity Of Operators Precedence of operators The precedence of operators determines which operator is executed first if there is more than one operator in an expression. Let us consider an example: int x = 5 - 17* 6; In C, the precedence of * is higher than - and...
