: In this tutorial, we are going to learn about the various arithmetic operators with their usages, syntaxes and examples. IncludeHelp, on June 02, 2020 What are Arithmetic Operators in C/C++? Arithmetic operatorsare the special symbols that are used for the Arithmetic / Mathematical operations...
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(){...
Bitwise right shift a >> b T T::operator>>(const T2& b) const; T operator>>(const T& a, const T2& b); Notes All operators in this table are overloadable. All built-in operators return values, and most user-defined overloads also return values so that the user-defined opera...

[operator] to avoid overflowThis warning indicates incorrect behavior that results from integral promotion rules and types larger than those in which arithmetic is typically performed. We detect when a narrow type integral value was shifted left, multiplied, added, or subtracted and the result of ...
OperatorDescription + The unary plus operator preceding an expression in parentheses forces the grouping of the enclosed operations. It is used with expressions involving more than one associative or commutative binary operator. The operand must have arithmetic type. The result is the value of the op...
