What do these operator do exactly

int m=5;

int n=4;

k= m&n;

or

K = m|n;

thx

Those are bitwise binary operators.

The operator | is the logical or. Definition: x or y is 1 iff one of them or both are 1.

The operator & is the logical and. Definition: x and y is 1 iff both are 1.

In binary:

m = 0101

n = 0100

Apply &- and |-operation using the definition:

Code:m n m|n 0 0 0 1 1 1 0 0 0 1 0 1 m n m&n 0 0 0 1 1 1 0 0 0 1 0 0

m | n = 5

m & n = 4

There are some more bitwise operators, read this thread for more info:

The operators || and && are relational operators and no binary operators.

(A || B) is 1 if (A > 0) or (B > 0), else 0.

(A && B) is 1 if (A > 0) and (B > 0), else 0.

Note that A and B are not necessarily bits, they can also be of type int, char etc.
