The bitwise Or operation is similar, except that a 1 is assigned to the result bit if either or both of the compared bits is 1. Xor assigns a 1 to the result bit if exactly one of the compared bits (not both) is
实际的数据没有没修改,如下面程序中的vectorv Bitwise constness 类的成员变量没有被修改,包括int accessCounter 我们的编程模型是logical constness,而编译器是bitwise constness,两者之间可能存在冲突。 解决办法 mutable / const_cast 移除成员函数的const classBigArray{ vector<int> v;// 保存实际数据的vector muta...

Version Used: VS 2015 Description: Section III.1.1.2 of the Common Language Infrastructure (CLI) defines the System.Boolean type to be of size 1 byte where a bit pattern of all zeroes denotes False and any other bit pattern denotes True...
The basic and most common logical operations are the operations of negation, conjunction, disjunction, and equivalence. These operations may be performed relatively simply by the physical elements of the digital computer; more complex operations may be reduced by a program to, for example, three log...
Logical Shift and Arithmetic Shift are bit manipulation operations (bitwise operations). Logical Shift A Left Logical Shift of one position moves each bit to the left by one. The vacant least significant bit (LSB) is filled with zero and the most sign
The second operand is evaluated only if the first operand evaluates to true (nonzero). This evaluation eliminates needless evaluation of the second operand when the logical AND expression is false. You can use this short-circuit evaluation to prevent null-pointer dereferencing, as shown in the fo...
