Hey guys. Can some one explain how this code works? I don't know what does this single & operator do.

int x=15; int y=7; if((++x<=15) & (y++==7)){ Console.Write(x); } else{ Console.Write(y); }

Single & operator is known as bitwise AND. It performs AND logic bit by bit. For example: 6 & 3 = 110 & 011 (binary equivalence of 6 and 3) = (1&0)(1&1)(0&1) = 010 = 2 For the given program, the operands have only one bit each. (++x <= 15) & (y++ == 7) = (16 <= 15) & (7 == 7) // y is 8 but y++ is 7 = 0 & 1 = 0 So, if condition is FALSE, and thus the else body is executed which prints 8 (current value of y)

&& is logical operator and & is binary operator(and gate) at your code (16<=15)&(7==7) false & true false then print y value out understand?
