How does Unary Operator '&' work

How does the unary operator '&' work ?

In a test project i ran this code:

int num = 50, num2 = 100;

int x = num & num2;


result: x = 32

int num = 100, num2 = 90;

int x = num & num2;


result :x = 64

How is this calculated ?

Answer

From MSDN:

Binary & operators are predefined for the integral types and bool. For integral types, & computes the logical bitwise AND of its operands. For bool operands, & computes the logical AND of its operands; that is, the result is true if and only if both its operands are true.

In your case it is integeral type version.

So:

 50 in binary is 00110010     
100 in binary is 01100100     
AND result is    00100000 (32 dec)
