因为所有的算术操作符(Arithmetic operators),其实就是所有的操作符,只接受32位或者64位的操作数。a作为一个16位无符号数,先要转换成32位无符号数,然后才能执行取反操作。 结果自然是前16位全部为1。 这个可能看上去很容易避免,比如我可以这样: #include<iostream>usingnamespacestd;#include<stdio.h>intmain(){...

Arithmetic Operators: + - * / %: modulus operator, gives the remainder 向下取整Floor, ⌊⌋表示;向上取整Ceiling, ⌈⌉表示。C整数除法无论操作数是正是负总是把小数部分截掉,在数轴上向零的方向取整Truncate toward Zero。 Increment and Decrement Operators: ++ --作为前缀 Assignment Operators: =...
Example: Arithmetic Operators in CThe following example demonstrates how to use these arithmetic operators in a C program −Open Compiler #include <stdio.h> int main(){ int op1 = 10; int op2 = 3; printf("Operand1: %d Operand2: %d \n\n", op1, op2); printf("Addition of op1 and ...
Arithmetic operators 算术运算符将标准的数学运算应用于其操作数。 Operator Operator name Example Result + unary plus +a the value of a after promotions - unary minus -a the negative of a + addition a + b the addition of a and b - subtraction a - b the subtraction of b from a ...
