What is a logical operator in c plus plus?

Answer 1

The boolean and operator in C and C++ is &&

a < 3 && b > 4 // relational

The bitwise and operator in C and C++ is &

maskresult = maskinput & maskvalue // bitwise

Answer 2

if you mean and in the condition statements the and operator is "&&"

but if you mean that AND in logic design like "0101+0001=0001" the operator is "&"

you can use the link: http://msdn.microsoft.com/en-us/library/z0zec0b2%28VS.71%29.aspx

// expre_Bitwise_AND_Operator.cpp

// compile with: /EHsc

// Demonstrate bitwise AND

#include <iostream>

using namespace std;

int main() {

unsigned short a = 0xFFFF; // pattern 1111 ...

unsigned short b = 0xAAAA; // pattern 1010 ...

cout << hex << ( a & b ) << endl; // prints "aaaa", pattern 1010 ...

}

Answer 3

All the logical operators in C++ are:

== (equals to)

!= (not equals to)

< (smaller than)

> (bigger than)

<= (smaller than or equals to)

>= (bigger than or equals to)

&& (and)

(or)

The logical operators is used to test if something is true. Example:

if(1 > 3)

{

cout << "Hello";

}

That will only happen if 1 is less that 3. Wich will always be true so it will execute no matter what.

Answer 4

There is no operator ' in C++. It is merely a token or symbol used to delimit literal characters:

char c = 'a';

The ' token is also known as a single quote, as opposed to " which is the double quote token which is used to delimit strings of characters:

char str[] = "Hello world";

To store a literal single quote in a character type, you must use the escape sequence \':

char c = '\''; quote, slash, quote, quote

However, single quotes can be used in strings without an escape sequence:

char str[] = "An ampersand ('&') literally means 'and'";
