Name  & (bitwise AND) 


Examples  unsigned int a = 60; // 60 = 0011 1100 unsigned int b = 13; // 13 = 0000 1101 unsigned int c = 0; c = a & b; // 12 = 0000 1100 

Description  Compares two expressions bit by bit and returns 1 for a position bit if both compared postitions are 1. Returns 0 for that position bit if one or both compared positions are 0. The following list shows all possible combinations: 1 & 0 // Evaluates 0 because the second is 0 0 & 1 // Evaluates 0 because the first is 0 1 & 1 // Evaluates 1 because both are 1 0 & 0 // Evaluates 0 because both are 0 

Syntax  expression1 & expression2
