·除法:区别于我们小时候写的除号“÷”和写分式时的“—”,在 C 语言中我们使用/作为除号,例如a / b表示a被b除。 除了我们熟悉的加、减、乘、除,在我们的 C 语言中,我们还有一种运算—— 求余(complementation) 运算(也称 模运算(modulo operation) )。顾名思义,求余运算,就是求两个整数相除以后的余数。
L’operatore modulo non può essere applicato a numeri in virgola mobile come float o double. Nel seguente codice di esempio, mostriamo il caso più semplice possibile per utilizzare l’operatore %, stampando i risultati del modulo 9 di un array int data....
The modulo operator % computes the remainder. When a=9 is divided by b=4, the remainder is 1. The % operator can only be used with integers. Suppose a = 5.0, b = 2.0, c = 5 and d = 2. Then in C programming, // Either one of the operands is a floating-point number a/b ...

优先级从上到下依次递减,最上面具有最高的优先级,逗号操作符具有最低的优先级。 所有的优先级中,只有三个优先级是从右至左结合的,它们是单目运算符、条件运算符、赋值运算符。其它的都是从左至右结合。 具有最高优先级的其实并不算是真正的运算符,它们算是一类特殊的操作。()是与函数相关,[]与数组相关,而...
The operators that work with the address of memory location such as the address-of operator (&) and the dereference operator (*). The sizeof operator (sizeof) appears to be a keyword but really an operator. C also has the type cast operator (()) that forces the type of an operand ...
