C++ logical operators

C++ logical operators

This is a small tutorial/clarification on C++ logical operators & , | , && and ||.

Consider this C++ source file:
#include using namespace std;

int main(int argc, const char* argv [] ){ //Proving conclusion: cout<<"Proving conclusion: "; cout<< (0x7 & 0x2)<

= Conclusion: =

| and &: Are bitwise operators.
Operate on all the bits and return the comparison.

ex:
111 & 010 = 010
110 | 001 = 111

|| and &&: Are boolean logical operators.
Will evaluate if each value is true or false, then return the boolean operation's result.
ex:
111 && 000 = (1 AND 0) = 0
111 || 000 = (1 OR 0) = 1
beware:
10 && 01 = (1 AND 1) = 1
10 || 01 = (1 OR 1) = 1
