Name   (bitwise OR) 


Examples  unsigned int a = 60; // 60 = 0011 1100 unsigned int b = 13; // 13 = 0000 1101 unsigned int c = 0; c = a  b; // 61 = 0011 1101 

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

Syntax  expression1  expression2
